FPR Front-Loading Seal Centrifugal
FPR: Easy Maintenance Centrifugal Pump
The Fristam FPR is a high performance sanitary centrifugal pump that features a front-loading seal for service in place.The Fristam FPR Series reduces maintenance time and effort. Designed with a front-loading seal, the FPR allows production personnel to service the pump in place—without special tools. FPR pumps have fewer parts, so processors have fewer maintenance parts to stock. FPR pumps handle flow rates up to 2000 gpm.

FPR Features
Heavy-Duty ConstructionThe 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.
Internal SealFristam’s unique internal seal uses the cooling and lubrication of the product to provide longer seal life.
Close Internal ClearanceFPR internal clearances are as tight as 0.5 mm, making the pumps highly efficient and very gentle on product.
Optimized ImpellerThe ‘optimized vane angle’ design of FPR impellers maximizes efficiency and allows for low NPSH requirements.
The FPR runs smoothly and quietly.
Inline Seal Changes
FPR Series centrifugal pumps reduce maintenance time and effort. Designed with a front-loading seal, the FPR allows production personnel to service the pump in place—processors no longer need to pull pumps out of line to change seals, single or double.
Easy Maintenance
Self-Aligning Shaft
The self-aligning FPR shaft design allows for easy installation and gapping. The concentric collar on the shaft prevents run-out, protecting from seal damage.
Less Maintenance Inventory
Only two seal sizes are needed to fit 25 FPR models. For each pump model, seal size remains the same regardless of motor size.
FPR pump shafts are designed to fit both the single and double mechanical seal arrangements. This reduces the number of shafts needed to stock for spare parts.
Simple Tools
No special tools are needed to service the FPR.
