Abstract
A device for floated pumps with coaxial, opposite, modular pistons (7), operated by double eccentric cams (5), comprises pumping groups operating in parallel onto one and the same working chamber communicating with safety valves - one for suction and one for sending - and they may be aligned, kept together by tie-rods in higher or lower number, thus allowing differentiated flows and consequently differentiated powers.
Said pistons (7) have a large diameter and a short run, and their sealing is determined by elastomeric, flexible membranes (8) resting on bevellings which assure the functioning thereof, even under high pressures.
Also said valves (17, 20) of the pump are formed with elastomeric, flexible membranes onto thin slits, which are efficient also under high pressures.
