The PAM-ES 20 series hand pump is a manual hydraulic delivery pump that is suitable for feeding single acting hydraulic cylinders. The pumping cycle is double acting, i.e. it generates pressure in both movements of the lever. This model is not designed to be fixed to a tank; therefore, an external tank with suction tube to be connected to the pump must be provided. This product is suitable for a lot of applications and, in particular, for emergency systems. (Actuating lever not included)
