G25 Series 20 Gear Pumps
  • Displacements
    1.4 to 5.3 in. 3 (23cc to 87cc)
  • Maximum Pressure
    3045 psi (210 Bar)
  • Maximum Speed
    3,600 rpm
Highly efficient birotational gear pumps with 14-tooth gear provides lower pressure ripple which results in lower noise amplitude and low noise operation. Gear sides and shaft journals are ground to a fine finish to further reduce noise. The cast iron construction also contributes to noise reduction.

G20-LS & G30-LS Load Sense Gear Pumps
  • Displacements
    1.41 to 9.82 cu. in. (23.0 to 161.0 cc)
  • Maximum Pressure
    4,000 psi (275 Bar)

Load sense, variable discharge gear pumps incorporate a patented load sensing control. This load sensing feature allows the pump to operate on a pressure signal based on the load requirements of the system, automatically altering the output and pressure flow at the pump. In addition, the pump senses a low pressure (unloaded) condition within the hydraulic circuit thus reducing horsepower consumption by up to 90% during standby periods.
G20 LS- Patent #5,244,358 and 5,368,061

To meet specific customer needs, Haldex Hydraulics can design multiple section pump configurations within any of the pump families. These pumps are ideally suited for providing power to multiple hydraulic functions from one power source. This allows for significantly lower hydraulic system costs when compared to the use of separate pumps and associated fittings and hoses.
Multiple pump configurations from separate pump families such as the combination of the G20 Series with a W-Series to form a G2009 can be designed to meet unique applications.
Multiple pump configurations are available with up to four sections with a wide variety of valving, shaft, port and mounting flange options.
