G1/2" Semi Rotary Hand Pump, 15 LPM

Semi-rotary hand pump is a manual pump used for transferring fluids, typically in situations where electric pumps are not feasible or available. This hand crank rotary pump operates by manually rotating a handle, which creates suction and pressure to move fluids.

Tips: Semi rotary hand pump working principle

A semi-rotary hand pump operates by converting manual rotational motion into a pumping action. The pump consists of a handle attached to a rotor inside the pump body. When the handle is moved back and forth, it causes the rotor to oscillate within a semi-circular chamber.

This movement creates a vacuum on one side of the chamber, drawing fluid into the pump through an inlet valve. As the rotor continues its motion, it compresses the fluid and forces it out through an outlet valve. The check valves ensure unidirectional flow, preventing backflow of the fluid.

Semi-rotary hand pumps are typically used for transferring various liquids, including water, oil, and chemicals, from one container to another. They are favored for their simplicity, durability, and ability to operate without electricity, making them suitable for remote locations or emergencies. The efficiency of the pump depends on the proper sealing of the chamber and the condition of the valves.
