Gear Pumps

The G20 gear pump is the first gear pump that delivers 76 l/min (20 GPM) and is available in three versions. Its new, innovative design features simplified connection points that make attaching accessories fast and easy. The unique rotary gear design ensures long product life with minimal maintenance.

The G20 is durable, manufactured from high-quality die-cast aluminum, easy to use, and engineered to last, featuring a self-priming rotary gear design.

Designed, tested, and approved for use with gasoline blends (up to E15), diesel blends (up to B20), and kerosene.

Gear pumps work according to the positive displacement principle. The liquid is sucked in on one side and transferred further on the outlet side with constant pressure.

When the gears are driven, a vacuum is created, causing the liquid to be drawn in. The liquid is then conveyed between the housing and the gear wheels. With this principle, the two gears fill each other up with liquid, ensuring uniform pulsation-free pump delivery.

Leakage currents (gap losses) occur between the gear tips and the housing wall.

These depend on the design (precision), temperature and density of the liquid, etc.

Modular design
Robust construction for low maintenance
Wide range of accessories, nozzles, filters, hoses, flow meters.
Gear pumps last approximately 3 times as long as vane pumps, but gear pumps have a gap loss. This means that they generally cannot build up as much pressure to pump more than 1.8 meters deep.
Easy to install
Field serviceable, approximately 10 minutes to change gears or sensor.
Die-cast aluminum and powder coated body, about 30% lighter and corrosion resistant.
