Gear Pumps are perfectly suitable for demanding applications in fluid transfer for dangerous liquids or expensive chemicals. They produce a very constant pulsation free flow without leackage.
The magnetically driven gear pumps have no shaft seals and are 100% leakfree. The pumps are perfect for dosing small volumes in a precise and reproducible way.

A gear pump is a centrifugal pump and consists of two cogwheels which rotate in opposite directions and mesh into each other at the input end of the pump.
The pump housing has an input and output connection.
The motor directly drives one cogwheel (driving) and the driving cogwheel drives the other.
The liquid is being sucked into the empty space between two teeth (see fig. I).
The liquid, trapped between the tooth spaces, is being transported to the output side (see fig. II).
After the liquid arrives at the output side, the teeth of the two gears fill each others empty spaces up, and the liquid is pumped into the outlet (see fig. III).
