The magnetic driven NMR pumps are designed for the chemical process industry. A leak-free magnetic drive is used to improve plant and personnel safety in industrial heating plants.
Conventional pumps, that use mechanical seals, are prone to leakage of solution. Mechanical seals depend upon the liquid film for lubrication and a trace amount of liquid escapes from the seal in the form of a vapor. Single and double seal systems are conventional but are subject to high operational cost and catastrophic failures. Why use a system of mechanical seals that will cause a leakage of material - short term cost.
The containment shell on the NMR replaces any mechanical seal and saves maintenance costs because 90% of all pump failures are caused by leaking seals. NMR pumps offer exceptional benefits to the user and fulfill all environmental protection rules. Maximum operating temperature is 500° F.
Construction
NMR-pumps are single stage volaute 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.
