Failure to install such relief devices could result in personal injury or damage to pump or property. CAT PUMPS does not assume any liability or responsibility for the operation of a customer’s high pressure system.Read all CAUTIONS and WARNINGS before commencing service or operation of any high pressure system. The CAUTIONS and WARNINGS are included in each service manual and with each Accessory Data sheet. CAUTIONS and WARNINGS can also be viewed online at www.catpumps.com/cautions-warnings or can be requested directly from CAT PUMPS. DETERMINING Rated gpm = “Desired” gpmTHE PUMP R.P.M.

R Components comply with RoHS Directive.MATERIAL CODES (Not Part of Part Number):BB=Brass NBR=Medium Nitrile (Buna-N) NY=NylonPTFE=Pure Polytetrafluoroethylene S=304SS STCP=Steel/Chrome Plated STZP=Steel/Zinc PlatedUNLOADER TYPEAn integral unloader with built-in by-pass is part of the discharge manifold to provide system pressure regulation and pump protec-tion. This pump also includes a fixed chemical injector for chemical application.OPERATION:Pump should be purged of air before commencing operation. Liquid must flow through the pump without discharge restriction to assure full system pressure is reached.Install a pressure gauge close to the manifold head of the pump to assist in setting system pressure and to periodically monitor system pressure.Setting and adjusting the regulator pressure must be done with the system turned on. Start the system with the unloader backed off to the lowest pressure setting (counterclockwise direction). Squeeze the trigger and read the pressure on the gauge at the pump. Do not read pressure at the gun or nozzle. If more pres-sure is desired, turn adjusting cap one quarter turn in a clockwise direction. Squeeze the trigger and read the pressure. Repeat this process until the desired system pressure is reached. Thread lock-ing nut up to adjusting cap.NOTE: Pressure is not set at the factory.SERVICE:The unloader should be serviced on the same schedule as the seals in the pump. Refer to 3DNX Service Manual for start-up, servicing of seals and valves, torque requirements and diagnosis and mainte-nance chart.INTEGRAL UNLOADERSPECIFICATIONS U.S. Measure Metric MeasureFlow ..................................................................................3.0 gpm (11.4 lpm)PSI Range ...............................................................100-2850 psi (7-196 bar)Inlet Port ...................................................................... 3/4” GHF (3/4” GHF)Discharge Port ..........................................................M18 x 1.0 (M18 x 1.0)7332 FIXED CHEMICAL INJECTORSPECIFICATIONS U.S. Measure Metric MeasureFlow ..................................................................................3.0 gpm (11.4 lpm)Nozzle Orifice ................................................................. 2.1 mm (2.1 mm)Hose Barb ...............................................................................1/4” (1/4”)Inlet Port .....................................................................M18 x 1.0 (M18 x 1.0)Discharge Port ........................................................3/8” NPTM (3/8” NPTM)Weight ............................................................................... 5.3 oz.

The type of hose , extended lenghts, reduced I.D. and fittings may create back pressure in excess of the low pressure nozzle rating and prevent the injector from drawing chemical. See hose friction loss Chart in Service Manual. Deduct hose friction loss from above low psi nozzle. Contact Cat Pumps for assistance with other options.CAUTION: Deduct the pressure drop shown in the performance chart from your desired system pressure to arrive at the maximum high pressure nozzle rating. This is essentail to avoid over-pressurizingthe pump. Models 3DNX25GSI, 3DNX27GSI1 Special, concentric, high-density, polished solid ceramic plungers provide a true wear surface and extended seal life.2 High tensile strength, forged brass manifold head with built-in integral unloader and eight mounting screws for exceptional strength.3 100% wet seal design adds to service life by allowing pumped liquids to cool and lubricate on both sides.4 Stacked Valve assemblies include stainless steel valves, seats and springs to provide corrosion-resistance, ultimate seating and extended life.5 Unique design and specially formulated V-Packings offer unmatched performance and seal life.441235CAT PUMPS1681 - 94TH LANE N.E.
