   Flexible combination: support multi-pump combination (such as double gear pump P2GH5-3X/063+GH3-2X/016)
10. Quick look-up table for selection
    Pump type, pressure range, efficiency advantage, cost typical scenario
    Plunger pump 200-420 bar high pressure and high efficiency (92-97%) high injection molding machine, hydraulic press, ship steering gear
    Vane pump 70-350 bar ultra-quiet (65dB) medium and high machine tools, metallurgical equipment, chemical pumping stations
    Gear pump 100-350 bar, dirt resistance, durable, low construction machinery, agricultural machinery, lubrication system
11. Selection suggestions
    Extreme high pressure demand
    Choose A4VSO series plunger pumps (such as A4VSO500HS) with a peak pressure of 400 bar, which is suitable for 500-ton hydraulic presses.
    Silent environment requirements
    Choose PV7-1X series vane pumps (such as PV7-1X/16-20), noise ≤68 dB, suitable for precision machining machine tools.
    Cost-sensitive applications
    Choose AZPF series gear pumps (such as AZPF-11-008), which are low in price and simple in maintenance, and are suitable for forklift hydraulic power units.
    Variable control requirements
    Priority is given to DFR-controlled plunger pumps (such as A10VSO28DFR), which can realize composite pressure/flow adjustment and save more than 20% energy.
