5.1.1 FIXED FLOW RATE PUMPING ELEMENTS
The pump may be configured with two fixed flow rate pumping elements (25 cm^3/ min for each pumping element.
The seal between the piston and pumping element casing is dry, as the insertion of a gasket is not required.
The check valve for the pumping element is has a cone-shaped seal. This solution guarantees optimal system sealing at high
operating pressures (max pressure of 380 bar).
The pumping elements are mounted on the pump casing without the need to disconnect the line pipes with a threaded
connection, which makes assembly/disassembly easier.
