Working Mechanism

  • In open-circuit piston pumps, the inlet to the hydraulic pump and the reverse flow on the hydraulic motor or actuator are connected to the hydraulic fluid reservoir.
  • A piston cup creates pressure difference by oscillation mechanism, where downstrokes cause the filling of pump chambers.
  • The upstroke of the piston forces the pump fluid out for use.

Features

  • Eaton X20 620 Series open circuit piston pumps feature a single-acting control piston and one-piece housing for low weight & leakproof compact design.
  • They come in 74 cubic centimetres and 98 cubic centimetres displacements and are feasible to produce over 100kW (134 hp) power.
  • These X20 Series pumps can withstand low margin pressures up to 150 psi with high stability & reduced heat generation.
  • They provide pressure, torque & electronic displacement control, load sense and swash sensor feedback for attaining exact controlled output.
  • These piston pumps have B-10 bearing life rated at more than 80000 hours at 2000 psi for high efficiency and long service life.
  • They further feature a stable fan drive control for quickly reaching the projected speed with increased stability and reduced oscillation.

Standards and Approvals

  • ATEX
  • ISO

Frequently Asked Questions

What is the recommended fluid cleanliness level for Eaton X20 620 Series piston pumps?

These pumps comply with the ISO cleanliness code of 21/18/13 to prevent contamination of fluids.

What mounting option is used in these open-circuit piston pumps?

SAE mounting (flange configuration).

How to start Eaton X20 620 Series piston pumps?

  • Before adding hydraulic fluid, make sure the reservoir & circuit are clear of debris and clean.
  • Filtered oil is poured into the reservoir until it reaches a level that will stop vortexing at the suction connection to the pump inlet.
  • External slave pump is recommended for cleaning the system by flushing and cleaning.

What type of piston shoes are used in these open circuit piston pumps?

Bronze piston shoes.
