Simpson 90028 Axial Cam Pump Kit

The Simpson 90028 is an axial cam pump kit rated at 3300 PSI with a flow rate of 2.4 GPM. It features an 8.6CAH specification and a 3/4 in OD connection built with aluminum construction. This unit is designed for pressure washer applications requiring reliable water displacement. It arrives in new condition ready for installation.

Suits high-pressure cleaning builds not maximum flow

This pump suits owners replacing a worn axial cam unit on a compatible pressure washer frame. The 2.4 GPM output matches many residential and light commercial machines. Builders needing higher volume delivery or a triplex plunger design for continuous daily operation should look at alternative pump types. The aluminum manifold keeps weight down for portable cart setups.

3300 PSI pressure rating decides fit

The 3300 PSI maximum pressure is the single figure that determines whether this kit matches your machine. Verify the original pump nameplate shows the same PSI limit and 2.4 GPM rating before ordering. Mismatched pressure ratings cause premature failure or unsafe operation. The 8.6CAH displacement and 12A electrical reference further confirm compatibility with specific engine drive configurations.

Questions about this item

What pressure washer engine horsepower is needed to run the 90028 pump at 3300 PSI and 2.4 GPM?

The pump delivers 3300 PSI at 2.4 GPM and requires an engine rated around 8.6 HP to reach that output.

Can the 3/4 inch outlet on this axial cam pump connect to the high-pressure hose from my older 3000 PSI machine?

Yes, the 3/4 inch OD outlet matches common 3000 PSI hose fittings, so the existing hose will thread on directly.

How can I verify the 90028 kit is producing its rated 3300 PSI after installation?

Attach a calibrated gauge to the pump outlet, run the engine at full throttle, and confirm the needle holds 3300 PSI at 2.4 GPM flow.
