The FPR housing, cover, and impeller are made from 316L stainless steel castings and forgings for more substantial mass. Other centrifugal manufacturers use thinner stamped or pressed steel.
Due to its solid construction, the FPR can withstand more hydraulic shock and cavitation which can ruin a pump.
Fristam’s unique internal seal uses the cooling and lubrication of the product to provide longer seal life.
Close Internal Clearance
FPR internal clearances are as tight as 0.5 mm, making the pumps highly efficient and very gentle on product.
The ‘optimized vane angle’ design of FPR impellers maximizes efficiency and allows for low NPSH requirements.
The FPR runs smoothly and quietly.
