Sealless Magnetic Coupled Centrifugal Pumps Type NML / NMB

General

Magnetic coupled DICKOW-pumps of the series NM are sealless pumps. The static containment shell forms a closed system with hermetically sealed liquid end.

Applications

Magnetic driven NM-pumps are designed to improve plant and personnel safety, especially when handling toxic, explosive or other dangerous liquids which react on contact with the atmosphere. For all these services the containment shell replaces the double acting mechanical seal with external fluid reservoirs and the necessary control equipment. NM-pumps therefore offer exceptional benefits to the chemical, petrochemical and allied industries, and protect the environment.

Max. capacity and differential head:
50 Hz – appr. 400 m3/h and appr. 150 m
60 Hz – appr. 480 m3/h and appr. 220 m
(appr. 2100 gpm and 720 ft)
The maximum operating temperature is 200°C (390°F) for NML-series and 240°C (464°F) for
NMB-series. Higher temperatures are possible with the pump types NMR / NMWR.
