About this product
This is a 4,000 PSI direct drive triplex plunger pump designed for Honda engines, specifically replacing RSV4G40 and RSV4G40HDF40EZ models.

This horizontal pump delivers high-pressure cleaning capability for demanding tasks.
Our take
If your pressure washer's pump has given up, this 4,000 PSI triplex plunger pump offers a robust replacement for specific Honda engine setups. The 4.0 GPM flow rate combined with high pressure makes it suitable for serious cleaning jobs. The direct drive design simplifies installation, and the 1" hollow shaft is a key compatibility point to check against your engine. It's designed for cold water, which covers most general-purpose pressure washing. While an aftermarket part, its substantial specs suggest it's built for heavy-duty use. The 16oz oil capacity is also a good indicator of its operational demands.
