MagnePump®: 1-1/2 HP Circulating Pumps

A magnetically coupled, packless, high-pressure pump


Parker Autoclave Engineers MagnePumps eliminate or reduce many of the problems associated with conventional pumps, such as leakage, contamination and packing heat generation. They are ideal for applications where purity of the fluid is a major consideration or where leakage of material could be hazardous such as nuclear and petrochemical hydrates loops. In addition, power loss is eliminated due to no seal friction, delivering full motor horsepower to the pumping unit. Also, when adverse conditions exist the magnet drive functions as a clutch, eliminating overload and motor burnout.


The 1-1/2 horsepower MagnePumps are a packless design that provides improved efficiency and high torque with reduced heat losses. They are designed for liquid service and are rated for up to 5,000 psi (345 bar) system pressure.
