Featuring ductile iron construction and ability to handle differential pressures up to 145 psi, Model A6 provides safe transfer of viscous, non-lubricating, volatile, or delicate fluids. ATEX-certified, positive displacement pump utilizes eccentric disc technology, which enables self-priming and run-dry capabilities while maintaining constant flow rate regardless of changes in viscosity and pressure. Equipped with 1 ½ in. suction and discharge ports, Model A6 has max flow rate of 25 gpm.
