Power
The Simpson MSH3125-S
Fueled by a 187cc (6 hp) engine, its axial cam pump can generate a forceful pressure of 3200 PSI (roughly 53 times that of a standard garden hose) and a flow rate of up to 2.5 GPM (CETA-certified values). When these values are taken together, they yield a cleaning power of 8000 Cleaning Units.
For this gas-powered pressure washer, the Honda GC190 engine is started using a time-tested pull-start mechanism.
Gasoline is stored in a fuel tank with a maximum capacity of 0.48 gallon.
Design & Handling
With its wheelbarrow-inspired design, the Simpson MSH3125-S aims for excellent mobility and stability, enabling effortless maneuvering and dependable performance across diverse environments. The sturdy welded steel frame ensures the longevity of the assembly, offering stability and protection for internal components, even during rigorous use. The handle adds to the MSH3125-S convenience of transport.
This unit, weighing 55 lbs, strikes a comfortable balance between portability and stability, ensuring easy maneuvering for users of various strengths. That weight is mainly due to the inclusion of the 187cc Honda GC190 engine and a solid welded steel frame. Even so, the MSH3125-S's two 10" pneumatic wheels maintain easy maneuverability.
