Volumetric Metering of the highest precision.

Gear metering pumps are designed as plate pumps. To this end, the gears are fitted into the center plate of the pumps with a precisely defined axial clearance. Due to their construction design, gear metering pumps achieve volumetric degrees of efficiency >90% in this layout with - predominantly - operation pount independant characteristics. This means that the metering quantity can be accurately set using the pump speed. Metering pumps are operated at considerably lower speeds than in the case of conveying pumps, wth common speeds of between 20 and 200 rpm, depending on the conveying medium.

However, accurate metering not only presupposed the fast and reproducible setting of the operating point, but also a low-pulsation feed of the conveying medium. It is obvious that gear metering pumps offer considerable advantages over other types of pumps.
