With and without self-rinsing
The Dual-Precision Series’ innovative design allows precise mixing, simultaneous dosing or out-of-phase delivery. Combining two metering pumps on a single motor saves space and reduces motor control requirements without sacrificing precision. Furthermore, relative dispense volumes never change because the pumps are driven by the same shaft.
Using different size pump heads and using different calibrations allow mixing ratios as high as 160:1. Rinse port options are available when pumping fluids that form precipitates.
The speed and direction are detected by an optical sensor for feedback independent of the stepper motor.
Depending on size, each pump head is capable of a displacement of 25 to 150 µL / stroke.
The Dual Series dosing pumps are manufactured for mixing ratios from 1:1 to 160:1. With two calibrated pumps connected to the same motor you'll never have to worry about relative motor speeds.
DPP pumps are all characterized by their robustness and performance. Wear and tear is at its lowest, and their smart designs ensure a sustainable reduction of operating costs.
Adjustable Stroke Volume
Our pumps are versatile. With angle adjustment, a metering pump can deliver various doses. This allows you to relieve one metering pump of larger volumes and create synergy.
Our pumps are made from materials that are resistant to a wide range of aggressive chemicals. This means our pumps can also operate reliably and precisely in even the most severe environments.
Every pump that leaves our factory is made-to-measure and designed exactly according to the technical requirements of our customers. All pumps are permanently marked for lot control identification.
100% Outgoing Test
Before any pump leaves our factory, it is stringently and extensively tested in accordance with its specifications. Test results are included for all pumps to confirm specification conformity.
