Micropump® Unveils New Ball Bearing Gear Pump Design

New design maximizes performance in aggressive heat transfer fluid applications

Micropump® is introducing a new design for its Series 5500 gear pump that combines its standard magnetic drive and cavity-style technology with an innovative ball bearing design. The design
provides superior pumping for commonly used heat transfer fluids.

Designed specifically for dielectric fluids like Fluorinert(TM) (trademark of 3M), the pump includes an open ball bearing that stabilizes the position of the gears, which minimizes friction. With less friction, the pump is subjected to less wear, thus extending service life. The minimized friction also eliminates material shedding, permitting a clean, pulseless fluid delivery. The unique pump design allows the dielectric fluid to be pumped through the open ball bearings to provide longer bearing life
and smooth rotational operation. Micropump's magnetic drive and o-ring seals keep the fluid securely inside the pump for a leak-free operation.

The Series 5500 ball bearing pump comes in a compact size and operates quietly. The pump's maximum performance pumping a dielectric fluid like Fluorinert is 21 L/min at 1750 rpm and 45 psi. A wide range of optional features, configurations and chemically resistant materials are available.

For more than 40 years, Micropump has led the fluid-handling industry in the developmenit of miniature pumps and systems for OEM and industrial applications. Micropump operates as a business unit of IDEX Corp., a world leader in positive displacement pump technologies and other industrial products. As an IDEX company, Micropump utilizes Kaizen, Lean Manufacturing and Six Sigma process improvement strategies to improve quality and increase value in its product.
