Tonkaflo* Pumps
SS Series
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,
and spray applications.
Features and Benefits
• 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
or flow.
• 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.
