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.

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.
