Pressure Regulators

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.

Relief/Pop-Off Valves

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

Pulsation Dampener

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

Pressure Gauges

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

Thermo Valves

Thermal valves help eliminate heat build-up in a closed loop system by allowing fresh water to enter.

Inlet Pressure Stabilizers

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

Pulse Pumps

Pulse pumps inject chemical downstream of the pump to prevent damaging the hardware.


Jetters convert high-pressure pumps into jetting pumps by isolating one of the three valve chambers.

Inlet Filter

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


A high-pressure shut-off gun allows the operator to control liquid flow from the pump to the nozzle.


Lances vary the distance between the gun and nozzle. Nozzles control the spray aperture/characteristics.
