MKPStainless Steel Magnetic Drive Chemical Process Pump

The sealless MKP magnetic drive pump is ideal to meet the stringent requirements of chemical processing and a multi-tude of other industries. This highly advanced and extremely energy efficient pump is built to handle a huge variety of fluids reliably and absolutely safely.

With its special design using an inverted drive configuration, the MKP requires no plain bearing carrier. The pumped fluid provides optimum lubrication and cooling of the single, centrally located impeller bearing assembly, also allowing solids-laden and low-boiling liquids to be pumped. Depending on the pumped medium, it can handle fluids containing solids in concentrations up to 30% with a particle size up to 1 mm.

The pump impeller rotates stably about a stationary axis on the gyroscopic principle, maintaining a perfect hydraulic balance. This minimises bearing loads, increasing the reliabil-ity of pump operation.

Added to its compact design with virtually no dead areas, the MKP is constructed with just a few, robust components. An intelligent modular system facilitates assembly and keeps the costs of spare parts, maintenance and servicing to a minimum.

The MKP is available in a variety of designs and configurations. In particular, a heat jacketed version allows molten sulphur to be pumped. Its connection dimensions and performance data conform to DIN EN ISO 2858, making the MKP easy to retrofit into any installation to replace old pumps.
