Direct-Displacement Control Pump

The Direct Displacement Control (DDC) pump features a built-in Neutral Return Mechanism (NRM), which contains linkages and springs.

Putting the NRM inside, rather than the normal location outside the pump, keeps it protected and always lubricated, thereby increasing machine life, providing consistent operation, and longer service intervals. The pump offers three displacements in one housing: 25, 30, and 35 cc. The DDC is designed for closed-loop operations including wide-area mowers, sweepers, mini excavators, walk-behind skid steer loaders, and small tractors.
