A10VG28DGM1/10R Rexroth A10VG Variable Pump 28cc 300bar

Product Overview

The A10VG28DGM1/10R-NSC10F043S / A10VG28DA1D3L/10R-NSC10F015SH belongs to the Bosch Rexroth A10VG series of swashplate high-pressure variable displacement axial piston pumps designed for closed-circuit hydrostatic transmissions. It offers true drop-in interchangeability with original Rexroth units—standard mounting flanges and ports—so no piping modifications are required. Every unit is 100% tested under simulated operating conditions to guarantee reliable performance in high-pressure closed systems. Featuring an integrated boost pump, flow is proportional to drive speed and displacement. Multiple control options deliver high power density and excellent dynamic response.

Expert Maintenance Tips

Ensure suction and charge lines are adequately sized; route case drain independently. Fully bleed the system before first start-up and maintain high fluid cleanliness. Use recommended viscosity hydraulic oil and inspect filters and oil temperature regularly. Lock control settings after adjustment. For long-term storage, fill with clean oil and seal all ports to prevent corrosion.
