About this product

This is a horizontal triplex plunger pressure washer pump, designed as a replacement or upgrade component. It features a 1-inch shaft diameter and is built for powerful performance, capable of delivering a maximum pressure of 4000 PSI (with a recommended 3100 PSI) and a robust flow rate of 4.0 GPM. Constructed from copper and aluminum, it's suitable for engines between 13-15 HP, offering a 3/4" NH Garden Hose inlet and a 3/8" Quick Connect outlet for ease of integration into existing systems.

Our take

If you're looking to replace a worn-out pump or build your own high-performance pressure washer, this horizontal triplex plunger pump is a strong candidate. The 4000 PSI maximum pressure and 4.0 GPM flow rate are impressive, indicating serious cleaning power for demanding jobs. I appreciate the durable copper and aluminum construction, which suggests good longevity. Compatibility with 13-15 HP engines and standard inlet/outlet connectors makes it fairly versatile. However, this is just the pump; you'll need the right engine and accessories to make a complete working unit. This is definitely for the DIY enthusiast or professional.
