Tonkaflo* Pumps
AS 40K Series
• Mixed Flow Stage Design delivers up to 74%
• High Grade Elastomers: all seal materials are
• New Higher Efficiency SS stages in the 40K
• Fabricated Stainless Steel Stages require less
Figure 1: AS 40K Series
The new AS40K pump (Figure 1) combines high flow
with the durability of stainless steel. The AS40K
pump is a multistage centrifugal pump with an all
stainless steel liquid end mounted on a high-thrust
bearing frame. AS40K pumps are available in 60 Hz
and 50 Hz models.
Especially designed for high-flow applications, the
AS40K pumps tolerate punishing applications and
harsh environments. AS40K pumps are ideal for use
in the power generation and municipal industries,
excelling in applications such as large-capacity
membrane systems, general industrial boost applications, sanitizing systems and higher temperature
water recirculation. In many applications one AS40K
pump can take the place of two pumps,
reducing both capital and energy costs.
Features & Benefits
• All Stainless Steel Construction makes AS
Series pumps more durable and less susceptible
to operator error. AS Series pumps are also
chemically compatible with hydrocarbons and
can perform within a greater temperature
range than the standard Tonkaflo SS Series.

almost any application. For pressure boost
applications, 4-inch inlets are available. For
transfer applications, 6-inch inlets are available
to connect with 6-inch piping and improve the
net positive suction head (NPSH) available to
the pump. Victaulic clamps reduce piping stress

pumps easier.
