Eaton Corporation has added new Group 2 (SAE A) cast iron series pumps to its Global Gear Pump (GGP) line. The new pumps are available in 10 displacements from 8.0cm3/rev) to 36.0cm3/rev with maximum operating pressure up to 310bar and speed up to 3,600rpm. 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 imparts greater durability and extends service life when compared to aluminum pumps or similar types.
The cast iron pump extends the product line’s capabilities into a whole new range of heavy-duty applications where durability is the key factor. They use specially-designed high wear-resistant bearings to achieve high pressure and speed ratings. They are also available with B- size shafts in the A-size frame to add even more torque and pressure capacity.
