Product Introduction
In the large volume flow water treatment system, the double suction centrifugal pumps play the role of two single suction centrifugal pumps running in parallel and greatly boost the pipeline arrangement efficiency. The ABD HDS horizontal axially split double suction centrifugal pump sucks water and discharges water in radial direction. Both the inlet and outlet pipes are arranged in the lower party of the split half body. In this way, the maintenance will not affect its base and pipline system. The rotor uses support structure on both ends which is stronger than the suspension support structure. The pumps of this series is characterized by long life, high efficiency, reasonable structure, low running cost, easy installation and maintenance. It is an ideal pump for water treatment, chemical industry, firefighting, air conditioning, ship-building and other industries.
Main characters
- Snail shell type pump body split into the upper part and the lower part. All inlet and outlet pipes are arranged in the lower part so that there is no need to remove the base and pipeline system during the maintenance.
- High head pump adopts dual snail shell design which balances the radial force during running and offer HDS series horizontal axially split Double Suction Centrifugal Pump life of mechanical seals and bearings.
- The design pressure can be 16bar or 25bar. The pump body will undergo water pressure test at the pressure equal to 1.5 times the design pressure.
- For the double suction structure impellor, the hydraulic design adopts CFD calculation for verfication. The cast piece adopts precision casting process and the flow channel surface roughness is less than Ra25.
- In the structural design of the rotor components, the impellor, shaft sleeve and shaft are connected via key and are adjusted axially and fastened by locking nut.
- The rotor components have passed dynamic balance verification and run stably.
- The replaceable seal ring structure ensures the running clearance between the pump body and the impellors and relatively high operating efficiency as well as convenient repair and replacement. It also avoids wear and tear, replacement of the pump body and impellors, largely lowering the accessory cost.
- The seal option indluces mechanical seal and packing seal. The seal can be replaced without removing the pump cover.
- The bearing structure separate from the pump body enables replacement of the bearing, sealed shaft sleeve and other parts without removing the pump body.
- The bearing has two configurations: grease lubrication and thin oil lubrication .
