• Protect the pump with an inlet filter or strainer to keep debris out of valves and seals.
• Pair with a correctly sized unloader valve and relief components to stay within rated pressure.

How the Pump Works

• Three ceramic plungers operate in sequence to pressurize water through stainless steel inlet and discharge valves.
• This triplex design delivers a nearly continuous flow with low pulsation for smoother gun and hose behavior.
• Slow-speed operation at 1,450 RPM reduces friction, lowers oil temperature, and extends component life.
• Lubrication and heat dissipation are managed through a durable crankcase, oil sight glass, and vented dipstick.

Maintenance Simplified

• Oil Sight Glass: Enables fast checks without removing plugs.
• Vented Dipstick: Makes oil changes simple and protects internal seals from overpressure.
• Service-Friendly Layout: Accessible fasteners and clear documentation support quick seal or valve service.
• Factory Break-In Oil: Allows the pump to go to work immediately after proper mounting and plumbing.
