The pumps are designed to be safe simple and easy to use and maintain. The construction is sealless and without rotating parts. The pumps are suitable for almost all different chemicals used by the industry today..With proper attention to maintenace, Tapflo Pumps will give efficient and trouble free operation. This instruction manual will familiarise operators with detailed information about installing, operating and maintaining the pump.0.2 The warning symbolsThe following warning symbols are present in this instruction manual. This is what they say.This symbol stands next to all safety instructions in this instruction manual where danger to life and limb may occur. Observe these instructions and proceed with utmost caution in these situations. Inform also other users of all safety instructions. In addition to the instructions in this instruction manual, the general safety and accident prevention regu-lations must be observed.This signal stands at points in this instruction manual of particular importance for com-pliance with regulations and directives, for correct work flow and for the prevention of damage to and destruction of the complete pump or its subassemblies.0. GENERALSTOP IOM manual Tapflo metal series pumps 5 1. INSTALLATION 1.1 Receiving inspectionAlthough precaution is taken by us when packing and shipping, we urge you to carefully check the shipment on receipt. Make sure that all parts and accesories listed on the packing list are accounted for. Immediately report any damage or shortage to the transport company and to us.1.2 StorageIf the equipment is to be stored prior to installation, place it in a clean location. Do not remove the protective covers from the suction, discharge and air connections which have been fastened to keep pump internals free of debris. Clean the pump thoroughly before installation.1.3 FoundationThe pump will operate properly without being fixed to a foundation. If fixation is needed for an installation, make sure the foundation is able to absorb vibrations. Use the fixing holes on the foot of the pump housings. It is essential for the operation of the pump to mount the pump with the feet in a downward direction (see sketch on next page).1.4 Suction and discharge pipingsSuction and discharge piping should be fully supported and anchored near to but independent of the pump. The piping to the pump should be a hose, to prevent undue stress and strain on the pump connections and the pipings.1.4.1 Turnable connectionsThe suction and discharge connections are turnable 180°. This simplifies the assembling and installation considerably. If you wish to turn the connections, slightly release the pump housing screws, then screw a threaded nipple into the connection and turn. 1.4.2 Connection of suction pipeRemember that the suction pipe/connection is the most critical point, especially if the pump is priming. Just a small leakage will dramatically reduce the suction capability of the pump. When connecting the suction pipe, following is recommended. 1) For satisfactory operation, use reinforced hose or corresponding (the suction power may other-wise shrink the hose). The internal diameter of the hose should be the same as on the suction connection (at the bottom of the pump) to have best suction capability.2) Make sure that the connection hose - pump is completely tight, otherwise the suction capability will be reduced.3) Always use as short suction pipe as possible. Avoid air pockets which can arise with long pi-pings.1.4.3 Connection of discharge pipeFor this connection it is only recommended a simple and positive flow connection. Use a hose or flexible piping (minimum one meter) between the discharge connection and any rigid fixed piping. Coil the hose at least one turn. All components (hose, pipe, valves etc) on the discharge piping must be designed for minimum PN 10.1.5 Air connectionScrew the air hose into the air intake on the center block of the pump with for example a bayonet coupling. For best efficiency, use the same hose diameter as the internal diameter of the con-nection on the air intake. STOPIOM manual Tapflo metal series pumps 6 1. INSTALLATION1.5.1 Air treatment systemThe air valve is constructed for oilfree air. Lubrication of the air is not allowed. However, if the air is very dry (laboratory air), the air may be lubricated with water. Maximum air pressure is 8 bar. As prevention purpose, a filtration of the air by means of a 5 micron filter or finer is recommended. Dirt in the air can under unfortunate circumstances be the cause of breakdown. Recomended air quality according to PN-ISO8573 is particles class 3, water class 4 and oil class 3 . To facilitate the operation of the pump we recommend an air treatment system connected to the air supply. These components should be included:1) Regulator to adjust the air pressure2) Manometer to read the actual pressure3) Needle valve to adjust the air flow4) FilterThese components are included in Tapflos Air treatment system which can be ordered from us.1.6 Example of installation1) Gate valve compressed air2) Filter and pressure regulator3) Flexible hose4) Needle valve5) Flexible piping6) Gate valve suction7) Gate valve discharge 8) Coiled flexible piping9) Flow gauge IOM manual Tapflo metal series pumps 7 1. INSTALLATION1.7 Recommended installationsThe Tapflo pump is flexible in the way you are able to install it. The in- and outlet ports are infinitely turnable more than 180° to fit various piping systems.1.7.2 SelfprimingThe Tapflo pump is designed to pull a high va-cuum. It is able to evacuate an empty suction pipe without any damage to the pump. The suction lift is up to 5 meter (16.4 ’) from an empty suction pipe and up to 8 meter (26.2’) from a wetted pipe. The suction capability de-pends on the pump size (see chapter 5.4)1.7.1 FloodedThe piping system is designed with a positive suction head. This is the best way of installtion where it is necessary to completely evacuate all liquid from the container, or where viscous (thick) products are transfered. ImportantDo not exceed 0,7 bar suction pressure. Hig-her pressure may cause premature diaphragm failure and irregular pump operation.1.7.3 SubmergedAll Tapflo pumps may be submerged into the liquid. It is important to make sure that all components which are in contact with the liquid are chemically compatible. The air exhaust must be led to the athmosphere by means of a hose.Air exhaust port dimension Pump size Air exhaust port T25 and T70 1/2" BSP T120 in alu and cast iron 1/2" BSP T120 in stainless steel 1" BSP T220, T420 and T820 1" BSPIOM manual Tapflo metal series pumps 8 2. OPERATION2.1 Health and safetyThe pump must be installed according to local and national safety rules.The pumps are constructed for particular applications. Do not use the pump on applications different from that for which it was sold without consulting us to ascertain its suitability. 2.1.1 ProtectionIn the interest of health and safety it is essential to wear protective clothing and safety goggles when operating, and/or working in the vicinity of Tapflo pumps. 2.1.2 Environments in danger of explosion - ATEXThe standard stainless steel pumps are not allowed to operate in environments in danger of explosion. Static electricity may occur in the pump under operation, which may cause explosion and injury. Special conductive pumps TX are available for such applications. All our aluminium and cast iron pumps are by standard ATEX approved, having model names TX... If you have purchased an ATEX approved pump (models TX...), follow below instructions and local/national rules for safe use.ATEX (directive 94/9/EC) classification of Tapflo TX pumps: IIB 2GD c T4STOPSTOPSTOPSTOPEarth connection of pump and other equipmentConnect a suitable earth wire to the stainless steel earth connection that is placed on the inside of one of the pump housings. Connect the other end of the earthwire to earth and also make sure that other equipment like hoses/pipes/containers etc are properly earthed/connected. 2.1.3 Air pressureThe maximum air pressure for Tapflo pumps is 8 bar. Higher air pressure than 8 bar can damage the pump and may cause injury to personel in vicinity of the pump. If you intend to apply a higher air pressure than 8 bar, please consult us.2.1.4 Noise levelAt tests, the noise level from a Tapflo pump has not exceeded 80 dB(A). Under some circumstan-ces, for example if the pump is operating under high air pressure at low discharge head, the noise can be inconvenient or hazardous for personel staying for long periods in vicinity of the pump. This hazard can be prevented by: - using suitable ear protection - lower the air pressure and/or raise the discharge head - lead the outcomming air from the place by connecting a hose from the muffler connection of the pump. You will find the air exhaust dimension in chapter 1.7.3. - use elastomer valve balls (EPDM, NBR or polyurethane) instead of PTFE, ceramic or stainless steel, provided that the elastomer is compatible with the pumped liquid.Epsilon protected equipmentGroup I I , explosive at-homspheres (other than mi-nes), gas group B (ethylene)Type of protection, con-structional safetyTemperature class, max surface temperature 135°C, ignition temperature of gas/vapour 135-200°C.Category 2, equipment pro-viding high level of protec-tion in areas where explo-sive athmosphere is likely to occur. G=gas, D=Dust. IOM manual Tapflo metal series pumps 9 2. OPERATION2.1.5 Temperature hazardsRaised temperature can cause damage on the pump and/or pipings and may also be hazardous for personel in the vicinity of the pump/pipings. Avoid quick temperature changes and do not exceed the maximum temperature specified when the pump was ordered. See also general max temperatures based on water in chapter 5 "Data".2.2 Before starting the pump- Make sure the pump is installed accordning to the installation instruction (section 1). - Filling of the pump with liquid before start is not necessary.- When installation is new or reinstalled, a test run of the pump with water should be conducted to make sure the pump operates normally and does not leak.- When installation is new or reinstalled, check the pump housing nut tightening torque (see chapter 5.5 "Data"). After approx 1 week operation, the torque should be checked again. This is important to prevent leakage.2.3 Starting and operating- Open the discharge valve. - Note Considering the suction capacity when air is still in the suction pipe, it is recom-mended to start with low air pressure/flow in the beginning. This is not necessary if the pump is filled with liquid before start. - When the pump has been filled with liquid, the air pressure/flow may be raised to increase the suction capacity of the pump. - The performance of the pump can be adjusted through the air supply by using a needle valve and a pressure regulator. The performance can also be adjusted by normal flow control on the discharge side of the system.2.3.1 Dry runningThe pump may run dry without any problem. If the pump runs dry for longer periods, it may cause premature wear of the components. Dry run protection systems are available, please contact us.2.3.2 Optimizing the pump lifetimeRunning at full frequenzy (maximum air pressure/flow) continiously will cause premature wear of the components. As a general rule, we recommend to run at half of the maximum capacity of the pump. For instance, a T120 pump should run continious maximum at 60 l/min.2.4 Pump stoppingThe pump can be stopped in two ways:1) Close the discharge valve. The pressure from the system will stop the pump automatically. This will not do any damage to the pump. The pump restarts easy when the valve is opened again.2) Stop the air supply. STOPSTOPIOM manual Tapflo metal series pumps 10 3. MAINTENANCE3.1 When the pump is new or reassembledIf the pump is new or reassembled after maintenance it is important to retighten the pump housing screws (pos 37) after a few days of operation. Make sure to use the right torque, see chapter 5.5.3.1.1 Performance testWhen installation is new, a test run of the pump should be conducted. Gauge the capacity at spe-cific air pressure/flow. This information is for use in checking performance as wear takes place. You will be able to set schedules for maintenance of the pump and to select spare parts to be kept on stock.3.2 Routine inspectionFrequent observation of the pump operation is recommended to detect problems. A change in sound of the running pump can be an indication of weared parts (see below "location of faults"). Leaking liquid from the pump and changes of performance may also be detected. Routine inspec-tions should be conducted frequently.3.3 Complete inspectionThe intervals for a complete inspection depend upon the operation conditions for the pump. The characteristics of the liquid, temperature, materials used in the pump and running time decide how often a complete inspection is necessary.If a problem has occured, or if the pump is in need of a complete inspection, see later this chapter "location of faults" and "dismantling of the pump". You are of course warmly welcome to consult us for further help. Weared parts should be carried in stock, see chapter 4.3.3.4 Location of faultsProblem Possible faultThe pump does not run The air pressure is to low The air connection is blocked Muffler is blocked Air valve is defect Dirt in the pump chamber Diaphragm breakdownThe suction is bad Suction connection is not tight Suction connection is blocked Muffler is blocked Valve balls are blocked Valve balls are damagedThe pump runs irregularly Valve balls are blocked Sealings are defect in air valve or center block Diaphragm breakdown Bad flow/pressure Pressurefall in incomming air Suction or air connection blocked Muffler is blocked Air valve is defect Valve balls worn out/broken Air in liquid Diaphragm breakdownLiquid leaks from the pump Screws on the housing not properly fastenedLiquid comes out of the muffler Diaphragm breakdown IOM manual Tapflo metal series pumps 11 3.5 Dismantling of aluminium and cast iron pumpsThe numbers put in brackets, refer to the part numbers in the spare part drawings and spare part lists in chapter 4.3.5.1 Before the dismantling procedure Be sure to drain all liquid from the pump.
