Cummins and Bosch develop new piston pumps for coach buses
Axial piston reduce costs by consuming less fuel
WELLAND—Cummins and Bosch‑Rexroth Canada have developed axial piston pumps that are flange-mounted to the power take-offs on the Cummins ISBe, ISLe and ISMe bus and coach engines.
Electromagnetic fan drive clutches, or hydrostatic fan drives with external gear pumps consume five per cent less fuel, reducing vehicle operating costs.
The A10VO and A10VNO axial piston fan pumps with through drive attaches to an FN4 auxiliary steering pump.
The steering pump consists of a hydraulic pump and motor, hydraulic oil tank and filter, and an electronic control card that operates a hydrostatic fan drive.
