Design feature

-Type DSJH process pumps are single stage,single suction ,radial split case,

-Overhanging centrifugal pumps see constitution figures.

-The DSJH pumps are especially suitable for pumping high temperature,high

-Pressure and inflammable,explosive or toxic fluids.The pump case is centerline mounted in order to equalize thermal expansion and contraction.This reduces alignment problems caused by case movement due to temperature differential between operating and ambient conditions to minimum limit.Pump cases of 4 -inch and above 4-inch discharge nozzle dia,are double volute to balance the radial force of pumps.
 

Advantage:

1.The pumps are full compliance with the API610 standards of American Petroleum Institute and have high reliability.

2.The efficiency of this kind of pumps is the first level in the world.

3.Parts of pump have wide universal degree and exchangeability.Some of parts can be used for several series to make production easy and favor the control for spare parts.

4.The cooling  fins are cast outsides of bearing housing which can increase cooled effects.And meanwhile.The rigidity of bearing housing is raised.The construction is new.There are kinds of cooling methods for the bearing,i.e.air.fan and water cooling.

5.The pump case is centerline mounted.The impeller can be assembled from two ends of pump case.It is convenient for maintenance.

6.The pump case is double volute to balance radial force.

7.The impeller is double suction construction.So there is a little end thrust.

8.The front and back is impeller wear rings are intentionally designed with different size.i.e.the wear ring which nears to thrust bearing is somewhat less than  the other to make pump have slight axial force and shaft work under tension conditions to avoid the clearance of rotor.

9.Cone fit is adopted for coupling and shaft.

10.Packing or mechanical seal of single and double face, ellow and landed can be used for the shaft sealing.
