Huade’s axial piston variable pump A11VLO is designed primarily for use in mobile applications. Huade Hydraulic has more than 40 years of experience in the design and manufacture of hydraulic components. Its axial piston variable pump A11VLO are comparable to Rexroth and have superior performance. They match Rexroth products in performance and are an affordable alternative.
Inlet—–Absolute pressure at port S (suction port)
Maximum permissible speed (speed limit)
Permissible speed by increasing the inlet pressure pabs at the suction port S or at Vg ≤Vg max
Nominal pressure: Max.design pressure at which fatigue strength is ensured
Maximum pressure: Max. operating pressure which is permissible for short-term(t <1s).
A minimum operating pressure pB min is required in the pump service line depending on the speed, the swivel angle and the displacement (see diagram).
The case drain pressure at the ports T1 and T2 may be a maximum of 1.2 bar higher than the inlet pressure at the port S but not higher than PL abs. max ————–2 bar.
An unrestricted, full size case drain line directly to tank is required.
Temperature range of the shaft seal ring
The FKM shaft seal ring is permissible for case drain temperatures of -25℃to +115℃.
For applications below-25°C, an NBR shaft seal ring is necessary (permissible temperature range: -40°C to +90°C).
