Internal Gear Pumps    is composed of front cover, inner rotor, outer rotor, pump body, main shaft, mechanical seal, bearing and other components. When conveying easily crystalline media, the front cover and the pump body can be designed with insulation jackets, which can be melted by steam insulation during work.

The outer rotor has the function of driving the inner rotor. The rotation is the same. The pump body and the crescent plate of the front cover separate the suction port and the discharge port. When the suction port is rotated, negative pressure is formed and the liquid is sucked in. The pump body is exhausted by pressure to complete the delivery of the liquid.
