EASTERN Centrichem
Centrifugal Pumps
Built to last.
Eastern Centrichem single-stage and multi-stage centrifugal
pumps are designed for a wide variety of process industry applications,
pilot plant operations, and laboratory uses.
And, just as important, they
are designed for long, dependable service.
Construction.
Each Centrichem pump is close
coupled for greater strength, and comes ready to mount directly
to a NEMA 56C, 143/5TC, or 182/4C motor. This design eliminates
the need for special baseplate mountings, couplings, and complicated
drives.
Pump chambers, rear housings,
covers and impellers are all precision castings to ensure that
the pump walls are smooth. This avoids crevices which can lead
to product contamination.
Precision castings also reduce
flow resistance to a minimum. This improves the hydraulic efficiency
to a level unmatched in pumps of this size.
Generous clearances and the
overhung shaft design of the single-stage pumps enable them
to handle corrosive liquids that contain low percentages of
solids. And the mechanical rotary seals make these pumps suitable
for extensive applications with acids, alkalis, and solvents.
Materials.
All models are available in 316 stainless steel and some in
Hastelloy C. These materials are suitable for a wide variety
of acid and alkali solutions.
Operating Limits.
Eastern's model D and J pumps are rated at temperatures up to
250 deg F, while models C and H can be used in applications
as hot as 450 deg F, and viscosities up to 100 cps.
Engineering.
Pulsafeeder will modify or adapt our Eastern pumps to meet severe
or unusual service conditions. We can also manufacture specialized
pumps to meet specific application requirements. Contact your
local Eastern distributor for assistance in determining what
- if any - modifications you need.

Mechanical Seal Options
Centrifugal pumps for dependable
service in the process industries.
 |
Eastern Centrichem pumps
utilize mechanical seals exclusively on all models. Mechanical
seals are the preferred sealing method in most applications,
and offer many advantages over conventional packed stuffing
boxes:
- Reduced friction, thus
reduced power consumption
- Zero leakage of product
- Elimination of shaft
wear
We offer a variety of seal
configurations which provide the best selection of elastomers
and mating faces in order to handle a wide range of corrosive
liquids. |
