Applications

The magnetic driven NMWR 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 vapor 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. NMWR pumps therefore offer exceptional benefits to the user and fulfill all environmental protection rules. Maximum operating temperature without water cooling is 800° F.

Construction

NMWR 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.
