FPR

Centrifugal Pump

Front-Loading Seal, Easy Maintenance

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. No special tools are needed to service the FPR.

Heavy-Duty Construction
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.

Internal Seal
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.

Optimized Impeller
The ‘optimized vane angle’ design of FPR impellers maximizes efficiency and allows for low NPSH requirements.

The FPR runs smoothly and quietly.

Front Loading Internal Seal

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.

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.

Pharmaceutical Options

All standard Fristam centrifugal pump stainless steel components are 316L. Special castings are available in low-ferrite stainless steel or high-performance alloys such as Hastelloy® and AL-6XN®. USP Class VI elastomers are standard for pharmaceutical applications, with perfluoroelastomers available. Seal material options include silicon carbide, chrome oxide-coated stainless steel, and carbon. Electropolishing and enhanced internal surface finishes to 15 Ra are available on most products. Casing drain and mounting options provide complete drainability critical for long-term system cleanliness. Pumps can be easily configured for steam-in-place sterilization, with no external cooling devices required.
