About this product
This Thomletha General Right Shaft Pressure Washer Pump is a belt-drive type, designed for hot water pressure washers. It delivers 3500 PSI and a maximum volume of 5.6 GPM, powered by a 4.5 HP gasoline engine. Constructed from stainless steel, it features a .945 inch (24 mm) shaft diameter and a blue finish. Key specifications include 1125/1450 rpm max pump speed, 40.6 oz crankcase oil capacity, and 1/2-14 BSPP-F inlet/3/8-19 BSPP-F discharge port threads.
Our take
For those in need of a serious hot water pressure washer pump, this Thomletha unit offers significant power with 3500 PSI and an impressive 5.6 GPM max flow. Being a belt-drive pump, it tends to be more durable and allows for lower pump RPMs, which can extend its lifespan compared to direct-drive models. The 4.5 HP gasoline power source provides autonomy from electrical outlets, and the stainless steel material is excellent for corrosion resistance, especially with hot water. The .945 inch shaft is a specific size to match. However, it's worth noting the 3500 PSI, while high, isn't the absolute highest available on the market, which might matter for specific industrial tasks.
