The Yb series self-priming rotary vane pump features a built-in relief valve and utilizes a vaned rotor for liquid transfer. Made of ductile iron with self-lubricating vanes, it offers excellent performance and can be used to transfer viscous and volatile liquids, while requiring less power than comparable pumps. It offers significant advantages in low-speed, high-flow transfers.
