In the PR pumps the pumping cylinders, with intake and delivery valves, are put in star-shape around a cam which, with the help of the plunger return springs, supply with the suction and pressing reciprocating motion.

The plungers’ measures are five, therefore the smallest ones consent higher pressures and the biggest ones supply superior capacities.

The pumping cylinders (as the relative valves), as of modular conception, are easily replaceable or changed with others of different bore if necessary to modify the pump characteristics.

Being planned for immersion or external assembly and with different shafts, the pumps PR allow many kinds of installation possibilities, even the coupling with gear pumps.

Thanks to the radial plunge pumps’ modularity HP, it is possible to chose the bore of the pumping to realize a pump which fully satisfies the pressure and capacity demanded by the customer.
