5.1
PUMPING ELEMENTS
The pump has two fixed delivery standard pumping elements (25 cm^3/ min for each pumping element).
The seal between the piston and the pumping body is of a dry type, with no gasket provided between the two.
The pumping element retention valve is of the tapered seal type. This solution is able to guarantee an optimum seal for the
system at high operating pressures (max. pressure of 380 bar).
The pumping elements are assembled onto the pump body without disconnecting the hydraulic line thanks to a threaded
cartridge design, facilitating assembly/disassembling.
