The PE series is manufactured by Gks-Perfekt, and is a hydraulic pump that is equipped with a 2/2 directional control valve. It is compatible with single-acting cylinders, and has pack which comprises a gauge and two 3 m hydraulic hoses. There are hoses that are fitted with quick-release, non-drip fasteners, and has female couplers on both sides that are compatible with GKS toe-jacks.
