Description
IMPORTANT: Some engines have longer output shafts and may require the optional 1/4″ gearbox spacers for proper installation. Predator engines are the most common example. If your engine has a longer shaft, please add the gearbox spacer kit available on this page.
*The flange should be flush to engine when fully seated to avoid damage while tightening bolts. If not flush when fully seated on shaft, then spacers are required.
Gearbox Drive for Extended Durability
This pump features a gearbox drive system, which reduces operating speed significantly compared to direct drive pumps. While direct drive units typically run at around 3400 rpm, gearbox-driven pumps operate at much lower speeds — often between 1500 and 1750 rpm depending on the configuration. This slower operation reduces wear and heat, resulting in longer pump life and making it ideal for commercial and continuous-use applications.
