An optional torque limiter is available for 75 cc/rev models of the company’s P1/PD series of medium pressure variable-displacement, axial-piston pumps. The torque limiter is designed to adjust flow in the circuit to keep the prime mover from stalling under heavy loads. The pumps are said to have a new design featuring a compact, round housing that is smaller and quieter than conventional pumps with comparable capabilities. It is offered in five different configurations.
