Before this takeover, Commercial Hydraulics had established itself as one of the largest world names in the manufacture of: hydraulic pumps, hydraulic gear motors, hydraulic piston pumps, hydraulic flow dividers and hydraulic valves. Now with the backing of Parker, Commercial Hydraulics continues to lead. In fact, their series of hydraulic gear pumps is often called the industry standard by which all other hydraulic gear pumps are measured.
Previously branded Commercial pumps, motors and flow dividers are still made to the same exacting standards by Parker. In fact, the only difference is that the previous Commercial product codes are now preceded by “PG” (Parker Group).
Hydraulic Pumps and Motors
Roller Bearing Gear Pump P30/31, P50/51, P75/76 series
– working pressures to 2500 psi
– Speeds up to 2400 rpm
– Robust cast iron construction
– A wide selection of standard shaft and mounting configuration
– Multiple sections are available
– Optional priority, two-speed, and unloader valves are available
– Single and Multiple pump/motor, Flow Divider, Piggyback and Winch Motor configurations are available
Rotary Flow Divider Intensifier FD30, FD50, FD75 series
– This equipment divides a single oil flow input into several output streams, in direct proportion to the gear widths used.
– The Rotary Flow Divider also acts as an intensifier, transferring energy from total oil flow to that portion being used.
Multiple Section Pump
– Available in up to five pump sections, providing five separate flows from a single output drive.
– The individual flows can be tailored to suit most requirements over a range of speeds.
Bush Bearing Pumps P315, P330, P350, P360 series
– Working pressures to 3500 psi
– Patented interlocking body design
– Bronze thrust plates
– Tandem, triple and cross-frame pumps available
– Wide range of integral valves for power steering, power brakes, fan drives and implement hydraulics
– Reduced system noise levels compared to earlier models and competitors’ pumps
– High power through-drive capability
Fixed Displacement Gear Pumps and Motors
– Commercial’s extensive range, with displacements from 10.6 to 249.9 cm3/r and working pressure to 3500 psi, can handle the most difficult and heavy work loads, efficiently and effectively.
– A wide sellection if standart shaft and mounting configurations is available to suit most drive requirements.
