This pump is equipped with a double linear piston which has a variable oil flow rate (l/min) at different working pressures (bar) up to 700bar.
This means an important increase in the oil flow rate at low pressures and an adequate oil flow rate suitable at high working pressures up to 700 bar for a considerable time saving when filling large hydraulic cylinders.
The main fields of application are: industrial tools, large plants, lifting, locking systems, large cylinders.
The same double piston in-line technology can be adopted on any other type of pump of the UP series (apart from the UPD series pumps which have double air motors).
