Jet-USA JTP100 II High Pressure Washer Replacement Pump

Product Overview

The Jet-USA JTP100 II is a practical replacement pump for pressure washer owners who want to get a machine back into action without replacing the entire unit.
If your engine is still good but the pump is tired, leaking, or no longer performing like it should, this kind of replacement can be a smart and cost-effective fix.

Why This Pump Stands Out

What makes this pump appealing is that it focuses on the core things buyers usually care about most: pressure capability, durable construction, and straightforward compatibility details.
It is designed for setups using a 3/4 inch shaft with a 5mm keyway, which makes it especially useful for people trying to match an existing washer rather than starting from scratch.

Built for Strong Pressure Washer Performance

The JTP100 II is rated to a maximum pressure of 275 bar, or 4000 PSI, with a continuous pressure of 193 bar, or 2800 PSI.
That gives it the sort of performance many buyers look for when replacing a worn pump on a serious home or worksite pressure washer.

Made for a 3/4 Inch Shaft

One of the most important details on any replacement pump is fitment, and this model keeps that front and centre.
It is designed for a 3/4 inch shaft with a 5mm keyway, which makes it easier to compare against your current pump before buying.

Forged Manifold and Aluminium Housing

Jet-USA highlights a forged manifold and an aluminium pump housing, giving this replacement unit a tougher, work-ready feel.
It is designed to offer durability while also helping manage heat during operation.

Integrated Unloader for Practical Operation

The integrated unloader is one of the useful built-in features on this pump.
It helps keep the setup more complete and can make the replacement feel more straightforward compared with piecing together multiple separate components.

Detergent Injection Included

This pump also includes a fixed-rate detergent injector.
That adds practical value for anyone who uses detergent or cleaning solution as part of their pressure washing routine, especially on vehicles, oily surfaces, or stubborn grime.

Pre-Filled with Oil

The listing notes that the pump is pre-filled with oil, which is a handy detail when fitting a replacement part.
It helps reduce setup fuss and gives the pump a more ready-to-install feel.

Built to Handle Heat Better

Jet-USA highlights a large finned air-cooled aluminium alloy housing designed to alleviate heat build-up.
That is an appealing feature for buyers who want a replacement pump that feels built for dependable ongoing use.

Good for Repairing Rather Than Replacing

A replacement pump like this can be a very practical option when the rest of the pressure washer is still worth keeping.
Rather than replacing the whole machine, it can help restore cleaning performance with a more targeted and economical repair.
