The pumps of the SLM AVP and SLM NVP series are universally applicable heavy-duty process pumps with magnet drive. They meet the highest requirements with regard to integrity, environmental safety, and ease of maintenance. The pumps are leak-free and particularly suitable for pumping toxic, aggressive, inflammable and other environmentally hazardous liquids in refineries, chemical and petrochemical industry.

Construction of the pump:

Construction and equipment of the single-stage, single-suction horizontal process-type centrifugal pumps correspond with the requirements of the API 685 standard. The pumps are of process-type design with radially split casing and flanged-on bearing support. The volute casing and the bearing support are fastened with their centerline feet to the base frame. By means of the centerline support, adverse consequences of thermal expansion and thus misalignment of the coupling are avoided. The impeller is of closed radial design.

Magnet drive:
The magnet drive eliminates the need for shaft passages since the motortorque is transmitted to the perfectly sealed chambers in the absence of any mechanical contact. This advanced technology involves the central coupling where the permanent magnets with the same even number of poles are alternating thus ensuring a perfect rotational symmetry. The concentric design of the coupling safely prevents any undesired radial and axial forces from acting on the journal bearings. Variation of the torque to any required operational mode is made by varying the system diameter and its height.
