Mahr MarSpin - Gear Metering Pumps with Block Mounting
This range of gear metering pumps was originally designed for the spinning of finest filaments – the typical first generation spinning pump. As a "real" spinning pump nowadays, this design is only used for very special applications like producing of aramide and carbon fibers. For all the other kinds of industries and applications this design is typically used as a standard metering pump with almost no limits.
The pump drive connection is available in following types:
- shaft types
- plug type
Gear pump with motor
- Base plate with mounting block
- Coupling
- curved tooth coupling
- cardan shaft
- all-steel coupling
- magnetic coupling
- Motor
- asynchronous gear motor
- servomotor / servo gear motor
- synchronous gear 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 sealing
- mechanical seal
- magnetic coupling
Atex Directive 2014/34/EU
A version according to the Atex directive is available for the pump as well as for the drive.
Heating or cooling for the gear pump Heating or cooling can be provided electrically as well as by the thermal fluid.
