Main Features
YB series Self-priming rotary vane pump with internal by-passvalve.The pumps use a rotor with sliding vanes
to draw the liquid. Thematerial of construction is nodular iron with sliding vanes built in aspecial self lubricating
material. Due to its efficiency, the pumpscan handle viscous and also volatile liquids and require less horsepower than other equivalent pumps. The pumps arecapable of higher flow-rates at lower number ofrevolutions than other designs.
Advantage
•Adjustable relief valve protects pump from excessive pressure.
•T-type strainers are available to protect pumpingsystem fromdamage caused by welding slag and other matter in the piping andtanks.
