This specification enables the manufacturing of stators with
integral gaskets at both ends. These are especially useful for
conveying toxic and aggressive products. Corrosion is avoided
because the stator jacket is not in contact with the product.
Moreover, this design meets the hygienic requirements of the
food industry.
To ensure we can offer the ideal pump for every application,
we have stators with numerous elastomer properties. Due to
different shrink factors, some are manu factured with specially
adapted cores.
Only the perfect interface between the rotor and the stator
can guarantee high efficiency and long life. An even compres-
sion between the two main pump elements is crucial. Unlike
stators made from cylindrical cores, which have a strong
pull-in area at only the middle, seepex stators are made from
appropriately adjusted cores. This manufacturing process
results in an even compression throughout the entire length
of the stator.
Key advantages
•
High level of volumetric and mechanical efficiency
•
Energy and cost savings due to
> low driving power
> lower starting and operating torque
•
Good pressure stability (even in lower speed range)
ensures optimum pumping characteristics across the
entire speed range
•
Reliable sealing prevents corrosion and premature wearing
•
Easy maintenance due to simple assembly
The standard stator design.

Our stators are manufactured individually for every size and
pressure stage. This production specification enables the
manufacturing of stators with integral seal gaskets at both ends.
As stators are subject to natural wear, an optional reten sion ing
device is available which considerably increases the stator’s
service life (see page 17 of this brochure).
The “Smart Conveying Technology”, SCT for short, goes a
step further: By separating the stator into two parts and the
detachable connection between the rotor and the coupling
rod, maintenance work is reduced to a minimum. That saves
time and costs and increases the productivity of your pumping
process. Moreover, this stator design can also be retensioned,
to increase the stator’s service life and restore the compres-
sion fit between the rotor and the stator, thus maintaining
optimum pumping performance without requiring extra stages
(see page 18 of this brochure).
