Construction and Performance Details

The Pump Made Ready TSS1511-VRT3-310EZ pump is classified as a positive-displacement, triplex piston pump. In this model, water is directed through three solid ceramic plungers, creating consistent flow and efficient high pressure delivery. Compared to other pump models like Comet, which are also widely used in the pressure washer industry, the TSS1511 from Barens is trusted for reliability, making it one of the most dependable options for commercial cleaning.

The forged brass manifold offers resistance to chemical exposure and wear, backed by a lifetime warranty. The crankcase is die-cast anodized aluminum, filled with an oil bath that continuously lubricates oversized connecting rods and tapered roller bearings. This combination of engineering reduces friction, prolongs life, and ensures pressure consistency even under continuous load.

Solid ceramic plungers are designed to handle repeated cycles of high pressure cleaning without premature wear. Continuously lubricated packings extend service intervals, making maintenance easier. Stainless steel valves withstand chemical solutions and harsh cleaning agents, ensuring the pump is suited to demanding cleaning purposes.

The VRT3-310EZ unloader enables precise pressure control and reduces engine strain at startup. A thermal relief valve prevents overheating by releasing heated water and allowing cooler water in. The inlet filter blocks debris, protecting internal parts. Each component is designed to be compatible with commercial pressure washers and their accessories, making the assembly fully ready for installation.

Unusual Noises

Grinding or knocking suggests failing bearings or cavitation.

Overheating

A hot pump may mean the thermal valve isn’t working or friction is building.

Pulsating Spray
