Interpump Gearboxes and Flanges

Interpump Gearboxes are used in conjunction with petrol and diesel engined pressure washers that need a gearbox. This type of gearbox connects the engine to the pump and ensures that the motor is running appropriately.

Steamaster has several Interpump Gearboxes that our professional customers have come to rely on. The Interpump RS99 Gearbox is suitable for use with Bertolini, Comet, and W Series Interpumps and has a maximum 6.5 horsepower usage. The Interpump RS151 Gearbox is a reduction gearbox for engines that have a one inch straight shaft and is compatible with most W Series pumps.
