Operation:

The Sigma K Hand Semi-Rotary Pump operates by moving the handle, which causes the shaft and wing piston, equipped with flap valves, to semi-rotate within the pump. The pump body contains a suction divider with flaps. The gland packing, compressed by the gland ring and nut, seals between the shaft and the pump cover. The standard model comes with threaded flanges and threaded counterflanges for ease of installation, with two lugs for wall mounting or similar structures.
