Magnetic drive centrifugal pump
max. 900 m³/h | NMWR series
DICKOW PUMPEN KG
Magnetic coupled DICKOW-pumps of the series NMW/PRMW are of sealless design.
The containment shell forms a closed system with hermetically sealed liquid end.
Applications
The magnetic driven NMW/PRMW-pumps are designed for hot oil applications, to improve plant and personnel safety in industrial heating plants. Leakage of hot oil at high temperature reacts to the atmosphere and turns into koke or tar. If the vapur pressure at operating temperature is above the atmospheric pressure, leakage vaporizes. In these cases, double mechanical seals are required in conventional pumps.
The containment shell replaces any mechanical seal and saves maintenance costs because 90% of pump failures are caused by leaking seals.
NMW/PRMW-pumps therefore offer exceptional benefits to the user and fulfill all environment protection rules. Maximum operating temperature without water cooling is 400°C (750°F).
Construction
NMW/PRMW-pumps are single stage volute casing pumps with closed impellers, back-pull-out design, with end suction and top centerline discharge flange. Foot mounted casings are provided as standard. Centerline mounted design is available as an option. Performance data and flange-to-flange dimensions comply with EN 22858 (ISO 2858).
