1. Introduction
This manual provides essential information for the safe and efficient operation, installation, and maintenance of the Cat Pump 340 Direct Drive. This pump is designed for high-pressure applications, delivering 4.0 GPM at 1800 PSI with a 1725 RPM BBCP motor. Please read this manual thoroughly before operating the pump to ensure proper use and to prevent damage or injury.
2. Safety Information
Always observe the following safety precautions to prevent personal injury or damage to the equipment.
- Ensure all connections are secure and leak-free before operation.
- Do not operate the pump without proper fluid supply. Dry running can cause severe damage.
- Wear appropriate personal protective equipment (PPE), including eye protection, during operation and maintenance.
- Disconnect power before performing any maintenance or service.
- Keep hands and clothing clear of moving parts.
- Do not exceed the maximum rated pressure or flow for the pump.
- Ensure adequate ventilation around the pump during operation.
3. Setup and Installation
Proper installation is critical for the performance and longevity of your Cat Pump 340.
3.1 Unpacking and Inspection
Carefully remove the pump from its packaging. Inspect for any visible damage that may have occurred during shipping. Report any damage to the carrier immediately.
3.2 Mounting
Mount the pump on a stable, level surface capable of supporting its weight and the forces generated during operation. Use appropriate fasteners to secure the pump firmly.

3.3 Plumbing Connections
- Inlet: Connect the inlet line to a reliable water source. Ensure the inlet line is adequately sized to prevent cavitation. A filter is recommended to prevent debris from entering the pump.
- Outlet: Connect the outlet line to your high-pressure system. Use high-pressure rated hoses and fittings.
- Bypass/Return: If a bypass line is used, ensure it returns to the supply tank or a drain, not directly back to the pump inlet, to prevent heat buildup.
3.4 Electrical Connections
Ensure all electrical connections comply with local codes and standards. The pump requires a 1725 RPM BBCP motor. Consult a qualified electrician for wiring if unsure.
4. Operating Instructions
Follow these steps for safe and effective operation of the Cat Pump 340.
- Prime the Pump: Before starting, ensure the pump is fully primed with fluid. Open all inlet valves and allow water to flow through the pump until all air is purged.
- Start the Motor: Turn on the power to the motor. The pump should start smoothly.
- Adjust Pressure: If equipped with a pressure regulator, slowly adjust it to the desired operating pressure. Do not exceed the pump's maximum rated pressure.
- Monitor Operation: Continuously monitor the pump for unusual noises, vibrations, or leaks during operation.
- Shut Down: To shut down, first relieve system pressure, then turn off the motor. Close all inlet and outlet valves.
5. Maintenance
Regular maintenance ensures optimal performance and extends the life of your pump.
5.1 Oil Changes
Change the pump oil after the first 50 hours of operation, then every 3 months or 500 hours, whichever comes first. Use only Cat Pumps specified crankcase oil.
5.2 Seal Replacement
Inspect seals regularly for wear or leaks. Replace worn seals promptly to prevent fluid bypass and pressure loss. Refer to the official Cat Pumps service manual for detailed seal replacement procedures.
5.3 Inlet Filter Cleaning
Clean or replace the inlet filter regularly to prevent cavitation and ensure proper fluid flow to the pump.
5.4 Winterization (if applicable)
If the pump is stored in an area where temperatures may drop below freezing, drain all water from the pump and lines to prevent freeze damage. Consider using an RV antifreeze solution for protection.
