Hydraulic Pump
A hydraulic pump consists of a pump body (cast iron/stainless steel), drive shaft, impeller/plunger assembly, and valving device, categorized as gear pump, vane pump, or piston pump by structure. It features high-pressure output (up to 35MPa), high volumetric efficiency (≥85%), low noise (≤75dB), and anti-pollution capability, with a temperature range of -20℃~80℃. Fluororubber seals resist hydraulic oil corrosion. Operation converts mechanical energy to hydraulic energy via sealed volume changes from impeller rotation or plunger reciprocation, with flow distribution via a valving plate for oil suction and discharge cycles. Widely used in construction machinery (excavators/cranes), injection molding equipment, marine hydraulic systems, and servo-driven applications in automated production lines, complying with ISO 4413 and GB/T 7031 fluid power standards.
