Fristam’s FPH and FPHP Series centrifugal high-pressure pumps supplement the capabilities of the Fristam multi-stage pumps. These models were designed specifically for recirculation in reverse osmosis systems or handling high process line pressures. As recirculation pumps, they offer greater flexibility when designing or upgrading your system.

The FPH handles inlet pressures up to 600 psi while the FPHP models handle inlet pressures up to 1,000 psi. The close-coupled FPHM allows for elevated inlet pressures (230 psi) without the added size and cost of a bearing block mounting.
