Mahr - Dosimar Gear Metering Pumps with Inline Mounting
Thanks to its lateral drilling, the Dosimar gear metering pump can be integrated directly into a wide variety of installation situations. It is often installed in meter mix machines, for example. The so-called mounting gib allows easy mounting of the pump in the machine. In addition to dosing polyurethane components like isocyanates and polyols, various resins and other liquids, this pump series is also used in the production of various fibres such as aramid and PAN. In addition, this pump meters additives in the polimerization process.
The pump drive connection is available in the following types:
- plug type
Gear pump with motor
- Base plate with mounting block
- Coupling
- curved-tooth coupling
- all-steel coupling
- magnetic coupling
- Motor
- asynchronous motor
- gear motor
- synchronous motor
The drive units are designed according to the operating conditions
Coating technologies take a significant key position in the development of new products. The various coating technologies enlarge the application possibilities of the base materials. Furthermore, a coating reduces friction, wear and corrosion. In principle, all named materials can be coated depending on the specification.
Diamond-Like Carbon (DLC) improves the properties:
- high surface hardness
- high wear protection
- smaller coefficient of friction
- better corrosion reduction to aggressive media
- higher chemical resistance / stability
- non-stick effect (reduced adhesion of polymers and other materials)
- high temperature firmness to 250°C
- excellent accuracy to size (no change of the high discharge accuracies)
- high economic efficiency through longer endurance and improvement of technological properties
- biocompatible, allows the use in the food industry and in the medical field
Sealing systems for the gear pumps
- stuffing box seal
- rotary shaft seal
- labyrinth seal
- mechanical seal
- magnetic coupling
ATEX Directive 2014/34/EU
A version according to Atex directive is available for the pump as well as for the coupling, motor and the complete unit.
Heating or cooling for the gear pumps Heating or cooling can be provided electrically as well as by the thermal fluid.
