Horizontal double suction centrifugal chemical pump

This Pump is an axially split, two stage pump designed to the API 610 (BB1) standards. With a double suction first-stage impeller, the pump is a natural solution for many low NPSH, high working pressure applications such as pipeline and transfer services. The pump fills the performance gap between the single stage  and multistage  pumps.

• Applications:
  LNG, Offsites and Waste Treatment, Cooling Water (power), Crude, Product and CO2 Pipeline, Dewatering and Water Supply (mining), Heavy Oil, Oil Sands and Shale, Gas Treating and Sulfur Recovery, Water Supply and Distribution (water), FPSO, Gas to Liquids, Fire Protection

Material: Cast steel, SS304, SS316, SS316Ti, SS316L, CD4MCU

Structure features:

Design:Full compliance with API610 8th edition specification

Construction:

1.The casing is axially split with the suction and discharge branches located in the lower half,so it allows the complete pump rotor with bearings to be removed for maintenance without disturbing the main pipework and valves.Short inspection and maintenance times

2.Impeller is symmetrically arranged.Rotor is in hydraulic balance.

3.Double volute casing reduced radial thrust and bearing loads.

4Large branches.Low flow velocities and high forces and moments accommodated.

5.Sizes of seal champer comply with API682 specification.Seal champer is designed to accommodate all single,tandem,dual and cartridge seal configurations.Cartridge seal is standard type.

6.Replaceable wear beings prevent the main components from being worn out.

7.Generous shaft diameter,small span.Reduce shaft deflection.Increase seals and bearing life.

8.Heavy duty rotor bearings.Special stiffness design makes the bearings run reliably.

9.Flexible spacer membrane coupling.

10.Optional instrumentation to monitor temperature,pressure and ib-ration,etc.

11.Welded common baseplate with drain rim.
