Eaton Introduces New Gear Pump For Construction And Mobile Vehicle Applications

EDEN PRAIRIE, Minn. … Diversified industrial manufacturer Eaton Corporation today announced the availability of new Group 2 A-Cast Iron series pumps in its popular Global Gear Pump (GGP) line. The new pumps are available in 10 displacements from 0.49 in3/rev (8.0 cm3/rev) to 2.20 in3/rev (36.0 cm3/rev) with maximum operating pressure up to 4,500 psi (310 bar) and speed up to 3,600 rpm.

This new product offering is a response to customer requirements for quieter, more durable pumps. A key benefit of the new pumps is that they are able to operate in the higher temperature environment created by upcoming diesel emission regulations. Cast iron, with its proven durability and thermal stability, is clearly the material of choice going forward, and the GGP A-Cast Iron series is ready to meet the challenge.

Because the GGP A-Cast Iron Series was engineered primarily for mobile applications, quiet operation was one of the principal design goals. Eaton’s GGPs offer advanced high-efficiency gear profiles, which provide low-noise and low-pressure ripple.

Mobile applications are also the reason the GGP A-Cast Iron Series uses cast iron material rather than the more common aluminum. Cast iron’s better thermal stability and higher strength permits more durability and extends service life when compared to aluminum pumps or similar types.

“The cast iron pump extends our Group 2 capabilities into a whole new range of heavy-duty applications where durability is the key criterion,” said Eaton’s Andrew Miller, product manager, gear. “They use specially-designed high wear-resistant bearings to achieve these outstanding pressure and speed ratings. They also are available with B- size shafts in the A-size frame to add even more torque and pressure capacity.”

Typical applications for the new A-Cast Iron pumps include skid steer loaders, wheel and front-end loaders, telehandlers, forestry equipment, agriculture harvesters and combines, fan drive cooling systems, and Industrial power units.
