Summary:In a pumping plant for oil filled power cables an air driven piston type pump (20) is used as primary pump. A PLS (26) is used to control the oil flow to the cable(s) (4). Improvements of the pump includes means for ensuring that the pump piston is operated also at low pressure and flow, and means for sealing off the piston rod to ensure maximum life of seals, to facilitate detection of possible leakages and to avoid contamination of the cable oil.
