Mounting and Location

Your pumping system is only as strong as your weakest component so it is critical that each component is carefully selected based on the same criteria as the pump. Each system requires carefully sized matching accessories to set and maintain system pressure, monitor system performance and protect system from over-pressurization. Not all systems require the same accessories. Minimally, we recommend a primary pressure regulating valve, secondary pressure relief valve and a pressure gauge. It is also critical to install and maintain a good inlet filter in your high pressure system. Even city water can contain abrasive particles that shorten pump life as well as other system accessories. Other accessories can be determined by application and installation.

To ensure the very best system life-cycle, Cat Pumps offers hundreds of accessories field-proven to protect your pump investment.

Pressure regulators are used on high-pressure systems to maintain and control system pressure.

Unloaders maintain system pressure and allow liquid to by-pass at low-pressure when not needed.

A relief valve, is a secondary device used to protect the pump from over pressurization.

A pop-off valve provides an economical solution to protect your system with an accurate and reliable secondary pressure relief.

Pressure gauges monitor system pressure and can be used on inlet or discharge plumbing.

Pulsation dampeners absorb pressure spikes and pressure fluctuations caused by the pump system.

Inlet regulators are designed to reduce and maintain inlet pressure to the pump.

Inlet stabilizers help maintain consistent pressure and flow to the inlet, improving pump performance.

Inlet filters are used on pressurized or gravity-fed systems to strain debris before entering the pump.

Low pressure seal monitors are designed to sense water leakage past the low-pressure seals.

Our oil level indicators can be installed in a variety of locations for convenient monitoring of crankcase oil. Kits are also equipped with oil drain plugs for fast and convenient oil changes.
