Magnetic drive centrifugal pump for the petroleum, chemical and nuclear industries
max. 320 m³/h, max. 40 bar | NM series
DICKOW PUMPEN KG
Magnetic driven 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 design 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 double acting mechanical seals with external fluid reservoirs and the necessary control equipment. NM-pumps therefore offer exceptional benefits to the chemical, petrochemical and allied industries.
Maximum capacity appr. 320 m³/h (1408 US-gpm), differential head 146 mLC (480 ft). Max. temperature for NMW-type 400°C (752°F) without external cooling. The maximum allowable working pressure is 40 bar (580 psi).
Construction
NML-pumps are single stage volute casing pumps with closed impellers, back-pull-out design, with end suction and top discharge flange. Sturdy legs are provided as standard for foot mounting on the base plate. Centerline mounted design is available on request. Capacity and outer dimensions comply with EN 22858 (ISO 2858).
If DICKOW-pumps of series NCL with mechanical seals are already in operation, a modification to magnetic drive is possible without removing the volute casing from the piping.
