High-Pressure Replacement Pump

The VEVOR triplex plunger pump delivers 4400 PSI maximum pressure and 4 GPM flow for residential pressure washers. It mounts on a 1 inch horizontal engine shaft and replaces worn units on compatible Simpson MorFlex and Santoprene models.

Compatibility and Limits

Suits owners of gas washers with horizontal engines that match the SAE bolt pattern, 4400 PSI rating, 4 GPM flow, and 1 inch shaft diameter. Builders using vertical-shaft engines, different shaft sizes, or higher pressure and flow requirements should look elsewhere.

Capacity and Headroom

Rated for 9 to 15 horsepower input, the pump handles daily cleaning of walls, sidewalks, and vehicles. It runs out of headroom when tasks demand pressure above 4400 PSI or flow beyond 4 GPM.

Questions about this item

What engine shaft diameter does this pump require?

The pump fits a 1 inch or 25.4 mm horizontal engine shaft and includes a shaft key for secure installation.

Will it bolt onto my Simpson MorFlex 40225 without modification?

Yes, the SAE bolt pattern matches Simpson MorFlex models 40224, 40225, 40226 and Santoprene model 41182 when engine orientation, PSI, GPM and connection sizes align.

How can I confirm the pump is delivering its rated 4400 PSI and 4 GPM after fitting?

Use a pressure gauge on the outlet; at full throttle with the supplied nozzle needle you should see up to 4400 PSI and a flow near 4 GPM.
