Features & benefits- The G-Series has a wide range of variations to meet diversifying needs and respond to special specifications.
- The G-Series can be designed and manufactured for difficult-to-transfer liquids and harsh operating conditions.
- Jacketed head or plate permits temperature control of the liquid being pumped.
What is an internal gear pump?
The gear section consists of a gear, which is the driving gear, and a pinion, which is the driven gear. The pinion is mounted on a pinion pin via a pinion bushing.
The center of the pinion is eccentric with respect to the center of the gear. As the shaft rotates, the chambers move fluid smoothly to the discharge port.
- Easy maintenance
- Wide range of applications
- Excellent durability
- Excellent NPSH characteristics
- Support for special specifications
There is only one sealing location. Disassembly, inspection, and cleaning of wetted parts are easy.
Its unique mechanism and tooth profile allow it to achieve a high vacuum level and excellent self-priming.
Capable of transferring all types of liquids across a wide range of viscosity and temperature.
Carefully selected materials, advanced processing, and surface treatments guarantee high durability.
Custom design and manufacturing are possible for difficult liquids and harsh operating conditions.
