The Groz Air Operated Double Diaphragm Pumps are designed for large volume transfer in a very short time. Driven by compressed air these pumps are used to transfer clean and particulate-laden fluids such as waste oil in industrial, automotive, chemical processing, oil and gas and in marine applications.

The pump’s self-priming design with internal check valves allows for a high suction lift even at dry start-up and with heavy fluids. The ability to run dry with no risk of damage and variable flow rate and discharge pressure makes these pumps suitable for a broad spectrum of applications. The pumps transport easily to the application site and the fully bolted design helps in easy repairs resulting in practically no downtime.
