Shertech self-priming, positive displacement, Teflon® roller pumps feature cast-iron construction for high temperature use. This series of pumps is designed for hot oil or frying oil filtration up to 375° F., meeting NSF-listing requirements. The non-clogging Teflon® roller design can pass limited particulates and reduce oil shear, increasing oil life. Pumps are configured with motors specifically for hot oil filtration applications where oil is heated prior to pumping and discharge pressure limitations do not exceed 40 PSI. They provide a nearly pulseless flow in applications where non-particulate and non-abrasive fluids are pumped. Not for use with water-based fluids. AC ODP single-phase motors have thermal overload protection. Complete package is easy to install.
