Tonkaflo SS series multistage centrifugal pumps
As the industry standard for reverse osmosis (RO),TONKAFLO SS Series pumps are backed by years of proven experience. The SS Series is a stainless steel multi-stage centrifugal pump with Noryl* plastic impellers. To reduce pump wear, SS Series pumps operate at lower speeds than single-stage pumps while achieving equivalent boost
pressures. The SS Series’ flexible, multi-stage design allows users to achieve their exact pressure requirements by adding or removing stages.
Offering the broadest range and best value, the SS Series sets the standard for the RO industry and serves as the standard for all Tonkaflo pumps.
4-inch (101.6 mm) and 6-inch (152.4 mm) 316SS shell shaft, inlet and discharge housings
Noryl plastic stages
Flow capacity of 1.5 to 300 gpm (0.34 to 68.1 m3/h)
Pressures up to 700 psid (48.3 bar)
