70122-LCW Danfoss 70122 Axial Piston Pump 19cc 210bar

Product Overview

The 70122-LCW / 70122-LCU / 70122-LCT belongs to the Danfoss (formerly Eaton) Series 70122 medium-duty open-circuit pressure or pressure-flow compensated axial piston variable displacement pump. It offers true drop-in interchangeability with original Eaton/Danfoss units—SAE A mounting flange—so no piping modifications are required. Every unit is 100% tested under simulated operating conditions to guarantee reliable performance in open-circuit systems. Featuring a lightweight aluminum housing and compact design, it supports pressure compensated and pressure-flow compensated controls, ideal for applications requiring low displacement, multiple configurations, and reduced weight in small to medium mobile and industrial equipment.

Expert Maintenance Tips

Ensure suction lines are adequately sized; route case drain independently with pressure not exceeding 2 bar. Fully bleed the system before first start-up and maintain high fluid cleanliness. Use recommended viscosity hydraulic oil and inspect filters and oil temperature regularly. Lock compensator settings after adjustment. For long-term storage, fill with clean oil and seal all ports to prevent corrosion.
