Hot Oil & Heat Transfer Magnetic Drive Pumps

High Temperature Magnetic Drive Pumps

Pumping heat transfer fluids provides a wide range of challenges to the end user. Many problems can be traced back to mechanical seal failures, resulting in costly repairs and down time.

By eliminating the mechanical shaft seal of a conventional centrifugal pump, Klaus Union’s sealless magnetic drive pump series SLM-NHO provides a more reliable, safer and more cost effective solution for heat transfer applications – 100 % emission free.

SLM-NHO - Sealless up to 840 °F without cooling

High performance magnetic couplings handle product temperatures up to
840 °F (450 °C) without external cooling. This allows insulating the pump, which makes it safer and increases the over-all efficiency of the whole system. Valuable heat energy stays inside the system.

It is often overlooked, how significant these energy savings actually are. With rising energy costs, savings add up over time and make the pump pay for itself within a matter of years.

By design, Klaus Union’s sealless magnetic drive pumps require very little maintenance, providing many years of trouble-free service – even under extreme conditions. Merely two oil-lubricated ball bearings, supporting the outer magnet carrier in the drive frame, require simple maintenance.
