Fact Sheet

Tonkaflo* Pumps
AS Series
cally compatible with hydrocarbons, and can
perform within a greater temperature range
than the standard Tonkaflo SS Series.
•

Fabricated Sheet Metal Stages require less
maintenance, and eliminate the need to balance pump impellers. The end result is
smoother operation, less vibration and longer
pump life.

•

Separate Bearing Frame increases pump
reliability and life because there is no thrust
load on the motor. In addition, this feature
allows AS Series pumps to be powered by standard motors.

•

Modular Liquid End allows service of the
mechanical seal without disassembling the liquid end of the pump. The AS Series’ modular
design also facilitates service of both pump and
bearing frame, and permits design flexibility
when positioning piping.

•

Industry Standard Mechanical Seal on pump
inlet delivers higher boost pressure capacity
and longer seal life, and simplifies the specifying
and finding of replacement parts.

•

Victaulic Connections reduce piping stress and
make the installation of AS Series pumps easier.

Tonkaflo AS Pumps
The AS Series (Figure 1) combines the benefits of
Tonkaflo, the industry-leading pump, with the
durability of all stainless steel construction. The AS
Series is a multi-stage, centrifugal pump with an all
stainless steel liquid end mounted on a high thrust
bearing frame. Engineered to be efficiently driven
by a standard motor, each of the AS Series pumps
offers dependable performance and long life.
And with over 200 standard models, there is
an AS Series pump to fit almost any 50 Hz or
60 Hz application.
Especially designed to meet tough industrial
demands, AS Series pumps tolerate the most punishing applications and harshest environments.
Ideal for membrane system applications, AS Series
pumps also excel in industrial boost applications
such as water soluble machine coolants, sanitizing
systems and higher temperature water recirculation.

All Stainless Steel Construction makes AS Series
pumps more durable and less susceptible to
operator error. AS Series pumps are also chemi-
