Marzocchi Aluminium Gear Pump

Marzocchi Aluminium Gear Pump

When you need reliable flow at a sensible price, the Marzocchi ALP aluminium body gear pump delivers. Built by one of the world's leading external gear pump manufacturers, the ALP series pairs a lightweight high-tensile aluminium body with hardened, ground steel gears — giving you durable, efficient performance across a wide range of mobile and industrial hydraulic applications. We hold Marzocchi stock locally, so you're not waiting on an overseas indent to get moving.

Why the ALP series

  • Lightweight aluminium construction — high-tensile aluminium alloy body, flange and covers keep weight down while resisting deformation under continuous, intermittent and peak pressure.
  • Hardened steel gears — case-hardened, quench-hardened, ground and fine-finished for low noise, low pulsation and long service life.
  • Pressure-compensated bushings — axial and radial compensation reduces internal leakage and lifts volumetric efficiency.
  • Modular and multi-stage capable — single units, or stack stages into modular multiple pumps to feed several circuits from one drive.
  • Wide displacement range — covers small auxiliary functions right through to high-flow main pump duties.

Key technical specifications

The ALP range spans four main groups. Continuous (P1) ratings shown — intermittent (P2) and peak (P3) ratings are higher and available on request.

  • P1 pressure tapers as displacement rises within each group — larger sizes carry lower maximum continuous pressure. Confirm the exact rating for your chosen size before ordering.
  • Recommended fluid: mineral-oil-based hydraulic fluid to DIN 51525 / VDMA 24317, operating between -10°C and +80°C (high- and low-temperature special versions available).
  • Filtration: keep contamination within ISO 4406 class limits appropriate to operating pressure for best pump life.
  • GHP series (cast-iron flange and covers) is also available where higher pressure ratings are required — ask us if your duty sits at the top of the ALP range.

Configuration options

  • Element type: front (A), intermediate (I) or rear (P) for modular builds
  • Rotation: clockwise (D) or counter-clockwise (S)
  • Shafts, flanges and ports: multiple standard and special options
  • Special versions: high/low temperature, reinforced shaft seal (TR), separate inlets (AS) and common inlet (AC, GHP only)

Applications

The ALP series suits a broad spread of the sectors FPD supports — agriculture, construction, civil, forestry and general industrial hydraulics — wherever a robust, efficient gear pump is needed for tractors, loaders, compact machines, tippers and auxiliary power circuits.
