The main components of the QGB series internal gear pump are a pair of gear pairs, consisting of a circular arc gear and a cycloidal gear. Internal gear pumps have the advantages of low noise, low flow pulsation, good suction performance, insensitivity to dirt, reliable operation, long service life, and easy maintenance and repair. It is particularly suitable for conveying high viscosity media with high-precision measurement requirements, as well as various liquids that do not contain solid particles (or solid particles ≤ 0.08mm). It can be used as a lubricating oil pump, fuel pump, infusion pump, hydraulic pump, etc. It is widely used in industries such as petroleum, chemical, pharmaceutical, food, textile, daily chemical, and highway asphalt construction.
The QGB series internal gear pump produced by our company is developed and designed based on the characteristics of high viscosity media. Components such as auxiliary line gears, circular arc gears, and pump bodies are machined using machining centers, with high machining accuracy and a customer volume efficiency of up to 90%. The maximum working temperature is ≤ 350C. Compared with peers in the same industry, it has the advantages of low relative sliding speed of gear pairs, minimal wear, low noise, strong suction capacity, high discharge pressure, and compact structure.
