Axial piston pump components

For over fifty years, ART Meccanica has been manufacturing precision components in Modena, Italy, for closed-circuit axial piston pumps used in hydrostatic transmissions. We work for some of the leading pump and hydrostatic transmission manufacturers, from prototype to series production, on components for pumps from 10 to 90 cm³/rev.

We manage the complete component cycle: from cast iron or steel blank to machining and dimensional and geometric inspection in our metrology lab. Special processes such as heat treatment are carried out by qualified partners under our coordination, so customers receive the finished part from a single supplier.

Complete machining cycle

In-house

  • Turning up to Ø 400 mm
  • Milling on machining centres, parts up to 600 × 600 × 600 mm
  • Drilling and piston bore boring
  • Lapping
  • Deburring and washing

Through qualified partners, managed by us

  • Heat treatment: case hardening, nitriding, quenching and tempering
  • Cylindrical grinding
  • Slotting, broaching and gear cutting
  • Parts up to 1 m³

We coordinate all external operations and incoming inspections: one supplier, one point of responsibility for the finished component.

Quality control and metrology

Every drawing characteristic is inspected in our metrology lab:

  • dimensions and GD&T tolerances (form, orientation, position)
  • roughness and profiles
  • hardness after heat treatment

Equipment: 2 coordinate measuring machines, 4 height gauges, 2 TAR-AL benches for setting and checking bore gauges, micrometers and calipers.

Quality management system certified UNI EN ISO 9001:2015 by Kiwa Cermet since 2003.
