The gear pump is compact and simple, with a limited number of moving parts. The gear pump cannot match the pressure generated by the reciprocating pump or the flow rate of the centrifugal pump, but it has higher pressure and throughput than the vane pump or vane pump. Internal gear pumps have better suction power than external gears. Although their application ranges from 1 cP to more than 1,000,000 cP, they are more suitable for high viscosity fluids.

Since output is proportional to speed, internal gear pumps are commonly used for metering and mixing operations. The small internal volume can reliably measure the liquid flowing through the pump, thus achieving accurate flow control.

Internal Gear Pumps    can be designed to handle corrosive liquids. Although they are usually made of cast iron or stainless steel, new alloys and composite materials enable the pump to handle corrosive liquids such as sulfuric acid, sodium hypochlorite, ferric chloride, and sodium hydroxide.

Our internal gear pump products are widely used in hydraulic systems of plastic machinery, leather machinery, pressure machinery, metallurgical machinery and forklift trucks, especially for energy-saving systems of servo inverter drives.
