Pressure Washer Pump (HP5535)

General Pump HP5535 – 47 Series Triplex Plunger Pump, 5.5 GPM @ 3500 PSI, Brass Manifold

The General Pump HP5535 sets the industry standard for professional-grade pressure washer pumps. Formerly known as the TS2021-B, this pump remains the preferred choice for contractors and commercial cleaning operations across the country.

Delivering up to 5.6 GPM at 3500 PSI, the HP5535 offers unmatched performance for high-demand pressure washing applications. It’s built around the 47 Series frame, a trusted platform known for its strength, reliability, and service life.

This unit features a forged brass manifold for superior corrosion resistance, along with a large-capacity, die-cast anodized aluminum oil-bath crankcase that keeps internal components running cool and well-lubricated. In addition, oversized connecting rods and a heavy-duty tapered roller bearing extend the life of the pump under continuous use.

The solid ceramic plungers reduce wear and improve sealing, while the continuously lubricated packings protect against breakdown. Furthermore, the pump includes unitized stainless steel inlet and discharge valves, ensuring smooth and consistent flow during every cycle.
