The 90R piston pump is engineered exclusively for closed-loop drive systems of tracked heavy machines. It provides stable high torque output, responsive variable displacement and robust shock resistance. Built with heavy-duty internal parts, it runs reliably in muddy, bumpy construction and mining environments with low noise and long service life.

FEATURES
The optimized swash plate provides rapid flow adjustment for flexible travelling speed control.
The integrated charge pump supplies supplementary oil and helps prevent air suction in closed hydraulic loops.
Hydraulic servo and proportional electric control options meet different automatic driving requirements.
Wear-resistant valve plates and piston assemblies reduce leakage, vibration and breakdowns during full-load operation.
Efficient power transmission reduces fuel consumption, while standard dimensions allow replacement without pipeline redesign.
