CAT PUMPS 67PPX39G1I Direct-Drive Plunger Pump Owner’s Manual

CAT PUMPS 67PPX39G1I Direct-Drive Plunger Pump

FEATURES

• The Triplex plunger design provides a smooth liquid flow.
• Special concentric, high-density, polished, solid ceramic plungers provide a true wear surface and extended seal life.
• Built-in flange mount for easy, direct mounting to most gas engines. Eliminates the need for pulleys, belts, and gearboxes.
• Integral Regulating Unloader with built-in by-passes standard for safety and pressure setting.
• Stacked stainless steel valve design for long life and easy servicing.
• A fixed Chemical Injector is standard and mounts directly onto the Unloader to provide cleaning flexibility.

All high-pressure systems require a primary pressure regulating device (i.e. regulator, unloader) and a secondary pressure relief device (i.e. pop-off valve, relief valve). Failure to install such relief devices could result in personal injury or damage to the 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 Datasheet. CAUTIONS and WARNINGS can also be viewed online at www.catpumps.com/cautions-warnings or can be requested directly from CAT PUMPS.

PART LIST

UNLOADER TYPE
An integral unloader with a built-in by-pass is part of the discharge manifold to provide system pressure regulation and pump protection. This pump also includes a fixed chemical injector for chemical application.

OPERATION
The pump should be purged of air before commencing with the operation. The liquid must flow through the pump without discharge restriction to ensure full system pressure is reached. Install a pressure gauge close to the manifold head of the pump to assist in setting system pressure and periodically monitor system pressure. Setting and adjusting the unloader pressure must be done with the system turned on. Start the system with the unloader backed off to the lowest pressure setting (counterclock-wise 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 pressure is desired, release the trigger, and turn the 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 the locking nut up to the adjusting cap and tighten the set screw. All high-pressure systems should have a secondary relief valve. Set the secondary relief valve 200-300 psi above the unloader setting.

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 the Service Manual for start-up, service of seals and valves, torque requirements, and Diagnosis/Maintenance chart.

CHEMICAL INJECTOR PERFORMANCE CHART

• Maximum Maximum Pressure Drop Across
• Orifice Injector Injecting Chemical Injector At System
• Size Model Pressure Draw Pressure (4000 psi)
• 2.1 mm 7367 358 psi 76.8 oz/min 288 psi
• The optimum performance of the chemical injector occurs with a 35 ft. high-pressure hose and a minimum 3/8” I.D. The type of hose, extended lengths, reduced I.D., and fittings may create back pressures in excess of the low-pressure nozzle rating and prevent the injector from drawing chemicals.

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 essential to avoid over-pressurizing the pump.

1. 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 designs and specially formulated V-Packings offer unmatched performance and seal life.
6. Crossheads are 360° supported for uncompromising alignment.
