Piston pumps with fan-control option

P1 Series hydraulic piston pumps now offer a proportional pressure control integrated directly on the pump. For off-highway vehicles with hydraulic fan-drive systems, this provides better control of cooling-fan speed independent of engine speed. The fan-control option eliminates a hose line (no plumbing from the pump to a remote valve) and creates a more-compact solution. An adjustable compensator further allows customers to limit maximum pressure. The fan control option is available for all P1 Series pumps including 18, 28, 45, 60, 75, 100, and 140-cc displacement models.
