| Eastern Centrichem single-stage and multi-stage centrifugal pumps are designed for a wide variety of process in dustry applications, pilot plant operations, and laboratory uses. And, just as importantly, they’re designed for long, dependable service.
CONSTRUCTION
Each Centrichem pump is close coupled for greater strength, and comesready to mount directly to NEMA 56C or 143/5TC or 184C motors. This design eliminates the need for special baseplate mountings, couplings, or complicated drives. Pump chambers, rear housings, covers and impellers are all precision castings to ensure that pump walls are smooth. This avoids crevices which can lead to product contamination. Precision castings also reduce flow resistance to a minimum. This improves their hydraulic efficiencies 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 their mechanical rotary seals make these pumps suitable for extensive applications with acids, alkalis, and solvents.
MOTORS
The standard motors for Eastern Centrichem pumps can be either single or three phase, 115/230 or 230/460 volt, 60 Hertz, TEFC motors. But we can furnish motors with other electrical characteristics, or enclosures, as needed. For general purpose applications or with excessive amounts of dust, dirt, or similar foreign materials that might harm the motor, we’ll provide totally enclosed motors. For hazardous applications involving flammable liquids or vapors we recommend explosion proof motors (approved by Underwriters Laboratories for Class 1 or 2 hazardous locations) equipped with explosion proof junction boxes. Continuous duty motors come standard on our industrial model pumps. Air motors are also available.
MATERIALS
All models are available in 316 stainless steel and some in Alloy C. These mate rials are suitable for a wide variety of acid and alkali solutions. Please consult our Chemical Resistance Chart for proper selection of metallurgy and shaft seal combinations.
OPERATING LIMITS
Eastern's model D&J pumps are rated at temperatures up to 250 F, models C&H can go to 450F, and viscosities up to 100 centipoises. |
