PR
Sliding vanes pumps type PR have been designed optimizing the air flow inside the pump to obtain high volumetric efficiency and extremely silent running.
The low operating speed, the cooled baffle plates in the inlet and outlet ports and the depth of the wwater jacket allow the PR Pumps to be extremely quiet in operation.
The uniform distribution of the air flow throught the PR pump and an effective cooling circuit result in produce a high volumetric efficency.
The introduction of a housing with a differential thickness and the sliding end plate design allows the range of PR Vacuum pumps to withstand failures which would normally create damage.
