Precision Gear Pump Overview
What are precision gear pumps?
Precision gear pumps can be used in any industry that require a fixed amount of supply and mixture of liquids, high-pressure discharge, etc.
The advantages of precision gear pumps include pulse-free discharge, metering discharge, long durability, compatibility of parts, diversity of pumps, and convenience in assembly and disassembly.
Hojin Technology’s precision gear pump has its own unique design developed through continuous R&D. Hojin Technology has a variety of pumps with different levels of viscosity and its products enable extremely accurate metering discharge.
Mechanism of a gear pump
- Inlet (green): Flowing into the grooves of a gear
- Outlet (red): Flowing out through the grooves of a gear
Operation of a gear pump
- Liquid flows into the inlet of the pump
- Liquid fills the grooves, casing, front, and back of the gear
- Liquid moves to the outlet along the internal circumference of the gear casing
- Amount of discharge of a displacement metering pump is proportional to the capacity and rotational speed of the pump
