Gear pump It is a common positive displacement pump, and its basic structure includes the following parts: pump body: the pump body is the main part of the gear pump, usually made of cast iron or cast steel. There are two or more gears inside the pump body, and their slots and the inside and outside of the pump body form a closed operation room. The pump body also has inlet and outlet ports.

Gear: gear is the core part of gear pump, which is made of steel, copper, aluminum and other materials. They have alveoli, which are evenly spaced and can engage with each other, merge and rotate. Inside the pump body, the gear rotates and slides along the outside of the pump body to form a pump cavity, which sucks the liquid from the inlet and pushes the liquid out of the pump body. Bearings and seals: bearings and seals are important parts of gear pumps, which can reduce the conflict and leakage of gear movement. The bearing can support the gear and shaft and reduce the wear of gear and pump body. Seals can prevent liquid leakage and ensure the normal operation of the pump. KRACHT gear pump The operating principle of the gear is to use the rotating motion of the gear to suck the liquid from the inlet into the slot between the gears, and then push the liquid to the outlet with the rotation of the gear. In this way, the gear pump can transport the liquid from the low-pressure area to the high-pressure area to achieve the purpose of conveying liquid.
