The Groz Air Operated Double Diaphragm Pumps are engineered with reduced parts for large volume transfer with maximum performance and reliability. 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 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, requiring no complex controls to install and operate. The fully bolted design helps in easy repairs resulting in practically no downtime.
