15 Frame Plunger Pump

Cat Pumps Pulsator Assemblies allow a user to activate a jetting action or return to a smooth high-pressure operation by opening/closing a ball valve. When opened, flow from one of the three inlet valves is bypassed through a hose back to the pump inlet, creating a jetting or pulsating action in the flow downstream. The Pulsator Assembly easily mounts to the inlet manifold valve plug on many models for a simple field-retrofit.
