Open loop piston pumps

Open loop piston pumps

 

 An open loop circuit piston pump is constantly circulating oil from the tank.  The most basic open circuit pump is fixed displacement.  To minimise power and heat losses, load-sense piston pumps vary their displacement to meet the demand required i.e. when no power is required the pump will de-stroke to a small standby flow until a demand is placed on it again.

The Danfoss series 45 open circuit axial piston pumps are designed with efficiency, reliability, and low noise in mind.  They are also designed to be modular and highly customizable in order to optimise your hydraulic systems.  Available in a wide range of displacements from 25cc to 147cc and with continuous pressures up to 310 bar, the series 45 will fit a broad variety of applications and needs.
