Some Tips To Choose The Right Pump To Bring Your Power Washer Back to Life:

1.Match Engine Orientation.

Horizontal Engine: The pump is installed horizontally onto the engine. Vertical Engine: The pump is installed vertically below the engine.

2.Match your machine's PSI And GPM.

(Engine power and pump performance need to be matched for optimal machine performance.)

3.Match the Engine Shaft Diameter.

The shaft diameter for vertical pumps is typically 7/8 inches.

The shaft diameter for horizontal pumps is either 3/4 inches or 1 inch.

(Please refer to the engine specifications to confirm.)

4.Match Current Pump Outlet Connection.

This will ensure that your attachments are compatible with the new pump. (If the connection does not match, you may need to use adapters or modify the setup.)

This pump comes with five nozzles and four mounting bolts and keyway. It fit my Honda GX 340 11hp perfectly. Good quality and heavy-duty construction. The pump is filled with oil from the factory. The pressure is outstanding. The same pressure of the original Cat pump that I replaced with this pump.

The pump section of our pressure washer failed and this replacement unit works great. The instructions were easy to follow with no issues during or after the replacement.

Haven’t had any issues after installing, it has worked out great, bolted right up and was ready to go. Very good pressure at a very good price!

We have dozens of machines for commercial use. Needed a simple back up pump if one pro grade needs service. This lasted less than 3 runs for 2 hour each use. You get what you pay for.
