Water & Process Technologies Fact Sheet Tonkaflo* Pumps Figure 1: Tonkaflo SS Series pumps As the industry standard for reverse osmosis (RO), Tonkaflo SS Series pumps (Figure 1) 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 re- quirements by adding or removing stages. Specifically designed to meet the challenges of industrial membrane systems, SS Series pumps excel in any high-pressure application. TONKAFLO SS Series pumps are ideal for water boost and recirculation in buildings, high-pressure transfer, • Corrosion-Resistant Construction including Noryl plastic diffusers and impellers and 316 stainless steel pump case and shaft ensure long-lasting performance. • Modular Liquid End allows service of the me- chanical seal without disassembling the liquid end of the pump. The SS Series' modular design also simplifies service of both pump and bear- ing frame, and permits design flexibility when positioning piping. • Wide Selection of pump models is available. There is an SS Series pump to fit any pressure • Separate Bearing Frame increases pump reli- ability by eliminating thrust load on the motor. In addition, this feature allows the SS Series pumps to be powered by standard motors. • Customized SS Series pumps are available on a pre-approved and limited basis. Contact your local sales office for availability and pricing. • Industry Standard Mechanical Seal on pump inlet delivers higher boost pressure capability and longer seal life, and simplifies specifying and finding replacement parts. • High Pressure Reverse Osmosis - The SS Series pumps feature the K-Bearing frame which eliminates alignment problems by close- coupling the pump to motors up to 100 Hp.
