These pumpsrepresent the ultimate device for recovering representative groundwater samples to depths of 250’(77 m) without compromising the chemical integrity of the samples. It is important that sampling devices faithfully transport representative samples for evaluation, sincegroundwater generally has temperature, pressure, gas content, and redox potential (oxidationreduction) conditions different than that of surface water. Devices that introduce air or gas into asample, or cause a sample to undergo significant pressure changes, are less desirable for preservingthe chemical integrity of the sample. Sampling systems that obstruct the water flow path by intricatevalving can change the pH of the water being sampled by degassing a portion of dissolved carbondioxide. Further, systems that allow the sample to be agitated with air can also affect the pH of thewater through iron hydrolysis reactions, which can have significant impact on both organic andinorganic chemical constituents.The chemical properties of the liquid in the well may determine which Monoflex pump is best suitedfor that particular application. Listed below are materials used in the construction of our pumps,in order of their chemical resistance (most inert to least inert). Note: During the manufacture of Monoflex Isomega® Bladder Pumps, extreme care is taken to avoidcontamination. Each pump is packaged to avoid contamination during shipping and handling. Itis important to avoid contamination of the pump during installation. Sun tan lotions, insectrepellents, and other incidental chemicals can contaminate a pump and affect initial sampling. It isbest to not move the pump to a contaminated site until the time of installation.RIGID MATERIALS PTFE (most inert)Stainless SteelPVC (Polyvinyl Chloride) FLEXIBLE MATERIALS PTFE (most inert) Viton® (a fluoroelastomer) Monoflex Division of Campbell Manufacturing, Inc.Prairie du Sac, WI • Bechtelsville, PA • Largo, FLPhone: 800-523-0224 • Fax: 610-367-5675website: www.campbellmfg.com08/03page 3MONOFLEX ISOMEGA® BLADDER PUMP SYSTEMISOMEGA® BLADDER PUMP OPERATIONMonoflex Isomega® Bladder Pumps obtain representative water samples frommonitoring wells. Isomega® Bladder Pumps employ a closed collection system thateliminates agitation or air contact with the sample. This, and the use of an inertPTFE bladder, ensures water sample integrity. The closed system provides the bestmethod available for recovering water samples having dissolved organic compounds(VOC’s). Isomega® Bladder Pumps may be used as portable or dedicated systems.Monoflex Isomega® Bladder Pumps should be used with the Monoflex I.V.P. PumpController. With the I.V.P. Pump Controller, Isomega® Bladder Pumps can operate withminimal head. A vacuum increases the pumping rates and makes pump operation lessdependent upon head.During operation, the Isomega® Bladder Pump chamber fills with liquid via the bottomscreen inlet, past the lower ball valve and into the pump chamber collapsing thebladder. Introduction of gas or air into the bladder causes the bladder to expand, closingthe lower ball check to force the contents of the pump past the upper ball check andinto the sample discharge line. Venting the bladder allows it to collapse, permittingthe pump to refill. A pressure of .45 PSI per foot of depth is required to lift a sampleto the surface. Monoflex Isomega® Bladder Pumps are designed to operate up to250’(75m) of head. The pumping rate will be dependent upon each of the following:* Controller type * Depth to the water surface* Pump submergence * Capacity of the pump body* Adjustment of the cycle time * Viscosity of the pumped liquid* Inside diameters of tubing lines * Flow rate of the compressed air or gasMonoflex Air/Gas Displacement Pumps are designed for initial well pumping, wellpurging prior to sampling or to pump contaminant from recovery wells. MonoflexAir/Gas Displacement Pumps have a larger pump chamber than Monoflex Isomega®Bladder Pumps. This makes them ideal for pumping large volumes of water orcontaminant. Monoflex Air/Gas Displacement Pumps may be used for sampling if airto water contact is permissible.Monoflex Isomega® Bladder Pumps can be converted to Air/Gas Displacement pumpswith minor modifications. Monoflex Air/Gas Displacement Pumps CANNOT beconverted to bladder pumps due to pump chamber requirements.For operating instructions, please see the Monoflex Air/Gas Displacement PumpOperation Instructions located in this manual.Isomega® PVC Bladder PumpMonoflex Division of Campbell Manufacturing, Inc.Prairie du Sac, WI • Bechtelsville, PA • Largo, FLPhone: 800-523-0224 • Fax: 610-367-5675website: www.campbellmfg.com08/03page 4MONOFLEX ISOMEGA® BLADDER PUMP SYSTEMISOMEGA® BLADDER PUMP OPERATION (continued)Monoflex Isomega® Bladder Pumps are designed for long term efficient use.

CONTROLLER OPERATION INSTRUCTIONSThe following are the operating instructions for the Monoflex I.V.P. Controller. This section willrefer to the drawing and parts listing shown above.Follow the directions one through eight of the “PUMP INSTALLATION” located on pages sixand seven of this manual. The following procedures will assist in timer and pressure settings forthe Monoflex I.V.P. Controller.Once all the tubing and air supply connections are secure and the air supply is functional, open theshutoff valve connected to the AIR INLET and note the reading on the SUPPLY PRESSUREGAUGE. A minimum of 60 PSI is required to operate the controller. Note: The maximum working pressure of the controller is 125 PSI.Set the PUMP PRESSURE REGULATOR by pulling up on the knob, turning the knob and thenpressing the knob down to lock once the proper pump pressure is set. Note the pressure readingon the PUMP PRESSURE GAUGE.To determine proper pump pressure, multiply the vertical distance to the pump by .45 PSI (.03 bar),then add 10 to 20 PSI (.7 - 1.4 bar), to that amount.Example:Sample to be evacuated at 100 feet (30.5m)100’ x .45 = 45 PSI (3 bar) of lift + 10 PSI (.7 bar) = 55 PSI total pressure needed.(1) Air Inlet - Supply from compressor, 125 PSImaximum.(2) Manual Drain - Used to drain internal water trap.Open periodically during and after each use.(3) Pump Pressure Timer - Adjusts how long thepump is pressurized during sample retrieval.(4) Supply Pressure Gauge - 60 PSI minimum requiredto operate controller.(5) Pump Pressure Gauge - Monitors pressure to thepump.(6) Pump Vent Timer - Adjust the length of time thepump body fills with liquid.(7) Vacuum Assist Switch - When turned on, thecontroller “deflates” the bladder during the vent cycleto maximize the amount of sample entering the pumpchamber.(8) Pump Pressure Regulator - For adjusting theamount of pressure sent to the pump.(9) Air Outlet - Air supply to the pump.(10) Vent Knob - Must be opened if the lid is closedduring controller operation, allows box to “breathe”.Monoflex Division of Campbell Manufacturing, Inc.Prairie du Sac, WI • Bechtelsville, PA • Largo, FLPhone: 800-523-0224 • Fax: 610-367-5675website: www.campbellmfg.com(Fill Pump)0 FEDCBA0,1-30s(Empty Pump)0 FEDCBA0,1-30s-1.0-30-20-10-0.50010203040 506070809010012 3 4 567 00204060 801001401201234 5 6 7118109I.V.P.Operation ManualCampbellQuality ground water monitoring products since 19731234657810908/03page 9MONOFLEX ISOMEGA® BLADDER PUMP SYSTEMI.V.P. CONTROLLER OPERATION INSTRUCTIONS (continued)Once the pump pressure is set, the controller will cycle the pump but the timers will need adjustmentto maximize the pumping rate. As the pump is cycling, the PUMP PRESSURE GAUGE will readeither the pump pressure you have set, zero, or a vacuum, provided the VACUUM ASSISTSWITCH is in the “ON” position.Keep in mind, when the PUMP PRESSURE GAUGE reads “pressure” the pump is pushing thesample to the surface. When the gauge reads a vacuum or zero, the pump chamber is filling withthe sample fluid. This action is also called “venting”.TIMER ADJUSTMENTSPUMP PRESSURE TIMER: This dial controls the amount of time the pump is allowed to pushthe sample to the surface. Note that too little time will not allow the pump to empty completely,and too much time is unnecessary because the pump has been emptied.PRESSURE ADJUSTMENTS: When the controller is operating, you will hear the valves inside“click” when switching operations from vacuum to pressure and then back to vacuum. During thepressure cycle, the fluid will empty through the discharge line of the pump. If the sample isflowing steadily out of the discharge tubing and suddenly stops when you hear the valves “click”,then the pressure cycle is too short. On the other hand, if the flow stops before you hear the “click”in the controller, then the cycle is too long.Note the increase and decrease directional lines on the timer dials. It is best to make only slightadjustments to the dials. Note the pump depth, static water level, and the letters on the dial for yourfuture reference.PUMP VENT TIMER: This dial controls the amount of time the pump is allowed to vent, or fillthe sample chamber. Note that too little time will not allow the pump to fill completely, and toomuch time is unnecessary because the pump is full. VENT ADJUSTMENTS: During the vent cycle, the sample is entering the pump body collapsingthe bladder inside. In order to know if the pump body is as full as possible, the amount dischargedduring the pressure cycle must be measured and compared to the stated pump body capacity.Considering the many variables such as pump depth and friction loss through the tubing, you shouldexpect some slight variance in sample amount. Monoflex Division of Campbell Manufacturing, Inc.Prairie du Sac, WI • Bechtelsville, PA • Largo, FLPhone: 800-523-0224 • Fax: 610-367-5675website: www.campbellmfg.com08/03page 10To increase the sample size per pump cycle, adjust the PUMP VENT TIMER slightly until younotice an increase in the sample size. If no noticeable increase is achieved, set the dial back to theprevious mark on the dial. The general idea of adjusting the dials is to achieve the maximum samplesize with a minimal cycle time.Note: For low-flow sampling, such as for VOC’s, decrease the pump pressure and increase theduration on the PUMP VENT TIMER to allow the pump adequate time to empty.Note: For well purging applications, the VACUUM ASSIST feature should be used while operatingthe Monoflex I.V.P. Controller. In situations where there is a minimal amount of head above thepump or partial pump submergence, use of the VACUUM ASSIST feature can substantiallyincrease the pumping results. See notations for Air/Gas pump use located in this manual.TROUBLESHOOTING* A short vent time will not allow the pump chamber to fill completely.* A short pressure time will not completely evacuate the pump chamber.* Sudden appearance of air in the sample fluid is a sign of slow well recovery.* Progressively reduced recovery volume is a sign of slow well recovery.MAINTENANCEAlthough we strongly recommend that any Monoflex I.V.P. Controller repairs be performed byMonoflex, please follow these maintenance tips to ensure top performance.* Remove and rinse the particle filters located in the shutoff valve and in the quick disconnect fittingon the AIR OUTLET with distilled water after each use.* When using an air compressor to operate the Monoflex I.V.P. Controller, use only an “oil-less”type compressor. This is very important if using an Air/Gas pump, as the drive air will come incontact with the water in the pump. This could cause oil to migrate from inside the pump to thewell.* Open the MANUAL DRAIN switch during and after each use, (while the controller is pressurized),to drain the internal water trap.*PLEASE READ* WARNINGS *PLEASE READ** When operating the controller with the lid closed, the vent knob must be open.* Maximum inlet pressure for the controller is 125 PSI (8.6 bar).* Controller operation without external in-line filters, or tampering with any of the mechanisms willvoid all warranties.MONOFLEX ISOMEGA® BLADDER PUMP SYSTEMI.V.P.

Avoid storing PTFE beneath or against other objects. Never store PTFE in hightemperature environments.CLEANING PROCEDURESThe Monoflex Isomega® Bladder Pump was designed to be easily disassembled, requiring few toolsand minimal time. Step 1: To clean the inside sample chamber, unscrew the top plug assembly (right hand threads),and lift the bladder assembly out of the sample chamber. Thoroughly clean the top assembly andexternal surface of the bladder by scrubbing with a soft brush. Exercise care during this procedureso as to not kink or puncture the bladder Step 2: Unscrew the bottom section and bottom ball check assembly. With a soft brush, scrub theinternal sample chamber and wash the ball check assembly thoroughly. Step 3: To clean the top recovery ball check, unscrew the fitting extension. Tip the top plug untilthe ball falls out. Scrub with a soft brush and re-install.PUMP DECONTAMINATION• Disassemble the pump carefully. All O-rings and ball checks must be cleaned and re-installedafter the pump is cleaned/decontaminated.• Do not use N Hydrochloric Acid on Stainless Steel; use extreme care when using on PVC. • Use extreme care when using Sodium Hypochlorite or Ethyl Alcohol on PVC. • Water based detergent (e.g. Liqui-Nox®), 20% Nitric Acid, 50% Hydrogen Peroxide, Sodium Hypochlorite, Isopropyl Alcohol, Ethyl Alcohol, and Hexane may be used to clean stainless steel. • Water based detergent (e.g. Liqui-Nox®), N Hydrochloric Acid, 20% Nitric Acid, 50% Hydrogen Peroxide, Sodium Hypochlorite, Isopropyl Alcohol, Ethyl Alcohol, and Hexane may be used to clean PTFE .MAINTENANCEController unit repairs are best performed at Monoflex.

Monoflex Air/Gas Displacement Pumps havea larger pump chamber than Monoflex Isomega® Bladder Pumps. This makes them ideal for pumpinglarge volumes of water or contaminant. Monoflex Air/Gas Displacement Pumps may be used forsampling if air to water contact is permissible.Advantages of Monoflex Air/Gas Displacement Pumps are their ability to safely pump turbid water andtheir dry run capability. With only two moving parts, a check ball beneath the pump chamber and in thesample discharge fitting, Monoflex Air/Gas Displacement Pumps can safely pump turbid water. In theevent of slow well recovery, Monoflex Air/Gas Displacement Pumps can run dry without damage to thepump.As with Monoflex Isomega® Bladder Pumps, Monoflex Air/Gas Displacement Pumps should be operatedwith the Monoflex I.V.P. Pump Controller. While the operating principles are the same with bladder andair/gas pumps, (venting, discharge, etc), please see the following notations to ensure maximumperformance of your Monoflex Air/Gas Displacement Pump System.* NOTE: Monoflex Air/Gas Displacement Pumps contain only two moving parts. A check ball islocated at the bottom of the pump chamber to prevent the captured water from re-entering the well whenthe pump is pressurized. Another check ball is located in the sample recovery discharge fitting to preventwater in the discharge line from re-entering the pump on the subsequent vent (fill) cycle. All pumps shouldbe disassembled and decontaminated after each use, (particularly if used in a monitoring well), and rinsedto remove any sand particles. Replacement PVC and Stainless Steel check balls and seats are availablein the event of wear from long term use.* NOTE: If the vertical distance from the I.V.P. Pump Controller to the static water level in the well isless than 35 feet, DO NOT use the vacuum assist feature while operating Monoflex Air/Gas DisplacementPumps. This will pull water into the I.V.P. Pump Controller that may cause damage to the controller andwill void the warranty.* NOTE: With as little as one foot submergence, Monoflex Air/Gas Displacement Pumps will fillwithout use of the vacuum assist feature under most conditions. Likewise, Monoflex Isomega® BladderPumps will fill to nearly 100% capacity if the top of the pump is submerged five feet below the staticwater line in the well before pumping. If the installation requires only partial submergence of theMonoflex Isomega® Bladder Pump, the vacuum assist feature should be used to maximize the samplevolume. * NOTE: For pump longevity and maximum efficiency, do not use Monoflex pumps when the intake(slot) size of the well is larger than .020 inches. Also, if sand or small particles are trapped underneatheither of the check balls during a cycle, the amount of water discharged may decrease from the previouscycle.08/03page 13MONOFLEX ISOMEGA® BLADDER PUMP SYSTEMPUMP SYSTEM ACCESSORIESI.V.P.
