General


The BP series pump is single stage, vertical cantilever, single and double suction pump. Liquid ends construction is the same white iron as in the other models. Bearing are grease lucricated.
The BPR is constructed similar to BP, except all the parts in contact with the pumpage are rubber coated, The rubber coating is used for corrosive applications.


Applications
This pump is suitable for metallurgy, mining, coal, power plants, building materials and general industrial applications that convey abrasive and high-concentration slurry. This pump has been used very successfully for ash removal in power plants.




Structure


1. Material construction optional
BP: abrasion resisting metal construction
BPR: anti-corrosive rubber construction
2. Do not need any shaft seal or sealing water. Also worked well under insufficient suction duty.
3. The type with “L” is the pump with extension shaft. It suitable to deep condition. It has guid bearing. So it more stable and used more wide. However the flushing water is necessary on the guide bearing part.
4. The agitator is available
We can assembly the agitator as requirements.

General




Model QS pump is a single-stage double-suction horizontal split centrifugal pump and used to transport pure water and the liquid of both physical and chemical nature similar to those of water, the maximum temperature of which must not be over 125℃ , suitable for water supply and drainage in factories, mines, cities and electric stations, waterlogged land drainage and irrigation of farming land and carious hydraulic projects.


Application


Aerospace Oil & Gas
Building Trades Power Station
Chemical Petro- Chemical
General Industry Pharmaceutical
Marine Pulp & Paper
Mining & Aggregate Water & Wastewater




Structure


Both inlet and outlet of this pump are placed under the axial line, horizontally and vertical to the axial line, the pump casing is opened in the middle, so it is unneccessary to remove the water inlet and outlet pipelines and motor(or other prime movers). The pump moves CW viewing from the clutch to it. The pump moving CCW can also be made.


The main parts of the pump are: pump casing, pump cover , impeller , shaft, dual-suction seal ring, muff, bearing etc.


The impeller is static-balance calibrated, fixed with the muff and the muff nuts in both sides and its axial position can be adjusted via the nuts and axial force gets balanced by means of the symmetrical arrangement of its blades.


The pump shaft is supported by two single-column centripetal ball bearings, which are mounted inside of the bearing body on both ends of the pump and lubricated with grease. The dual-suction seal ring is used to reduce the leak at the impeller


The flexible couplings connect the pump with the motor directly. For pumps driven by belt, there must be an intermediate bracket fitted for supporting the belt pulley.
