Bosch Rexroth Silence Gear Pump

Advantages of the Bosch Rexroth Silence Gear Pump

• Significantly reduced noise: The Silence Plus gear pump reduces noise emissions by an average of ~ 15 dB(A) compared with conventional external gear pumps.

• Low flow pulsation & vibration: Continuous, smooth fluid delivery via helical teeth and optimized gear design lowers flow pulsation (by up to ~ 75%) and reduces vibrations in connected hydraulic systems.

• High pressure capability: Suitable for demanding hydraulic applications — many Silence/Silence Plus pumps support pressures up to ~ 280 bar.

• Wear-resistant design & long service life: Hydrostatic bearings compensate axial forces in helical gearing, enabling wear-free operation and extended life, even under high pressure.

• Versatile integration: Available in multiple displacement sizes (various cm³/rev), with options for drive shafts, flanges, and multiple-pump combinations — facilitating retrofit or custom hydraulic power units.

• System efficiency: High hydraulic efficiency and stable flow reduce energy losses, heat generation, and system noise — improving performance and operator comfort over conventional pumps.
