Product Overview

BY type centrifugal oil pump includes single-stage cantilever centrifugal pumps,single-two-stage two-end supporting centrifugal oil pump and multistagecentrifugal oil pumps three sub- series. Single-stage cantilever centrifugal oilpump is developed and renovated by the Shenyang Water Pump Institute  and this company, on basic of single-twocantilever centrifugal pumps of the old Y -type centrifugal pumps, drawinglessons of various characteristics from the existing domestic centrifugal oil pumps,and in accordance with the American Petroleum Institute "API610 petroleum, heavy chemical and industrial gas pump " standard.

Applications: petroleum refining ,petrochemical and chemical industries , and delivery of liquid petroleum gasand other media without solid particles;

Performance advantages: the basic performanceparameters inherited Y -type centrifugal pump type spectrum, easy for selectionand replacement. Execution API610 standards; Cancel the two-stage structurecantilevered form, enhances the rotor stiffness, high reliability, small size,light weight, high efficiency hydraulic model selection; Efficiency up of 5-8 %compared with Y -type , good cavitation performance;

Technical Parameters: Flow Q = 1.5-360m3 /h, head H = 18-205m,

transmissionmedium temperature t = -45 ℃ - +420 ℃.

Performance advantages:
1,Basic performance parametersinherited Y-type centrifugal pump type spectrum, easy for selection andreplacement;
2,Implementation API160 standard; pumpdischarge size cancel the diameter Φ65, Φ125, etc.; pump materials perform API610 standard specifications.
3, Abolition of two cantileveredstructure type;
4, Enhances the rigidity of the rotor,to improve the reliability;
5,Small size and light weight to reducemanufacturing costs of the pump, and enhance market competitiveness;
6, Best selection of efficienthydraulic model, the efficiency up of 5-8% compared with Y-type offers goodcavitation performance.

Applications

BY cantilever single-stage centrifugal pump is mainly used inpetroleum refining and transporting petroleum processing apparatus and itsproducts, as well as transportation of flammable, explosive, toxic cleaningliquids and other similar liquids.

Flow rate Q = 1.5-360m3 / h, head H = 18-205m, the transmissionmedium temperature t = -45 ℃ - +420 ℃

Structural features

BYcantilever single-stage centrifugal pump is cut spit up, with two suction ways:axial suction and top suction.

Whenthe transmission medium temperature t <200 ℃,use of standard API610 OH1structure, means pump foot-mounted type; when transmission medium temperature ≥200 ℃,use of OH2 structure API610 standards, means pump centerline mountedtype.

Radiallysplit casing, particularly suitable for conveying high temperature, highpressure and flammable, explosive or toxic liquids. Seal chamber (stuffing)outside is cooling room, to cool; seal type can be soft packing seal andmechanical seal, execute "API610 standard" requirement, selection by useron basic of a variety of mechanical seals and piping systems for single-stagepump cantilever households.

Pumpcase is rare-open structure, with a diaphragm pump coupling with longersegments, repair piping and pumps without moving the core components of themotor , good maintenance.

Theimpeller is whole casting type, the balance of axial impeller advocated rely onback-sealing ring and impeller balance hole, residual axial force to withstandby a diagonal contact ball bearings, bearing lubrication is oil valley style, itcomes slinger for small shaft diameter.Special heat-insulating cooling chamberfor bearing suspension.

Working conditions

Thispump together with motor for indoor use or outdoor use, class of explosion-proofand degree of protection depends on the motor. Pump with same class of explosion-proofand the degree of protection, please be sure to specify these requirements atthe time of ordering the product
