DY and SDY series centrifugal pumps are developed by our company which relied on advantage of aerospace fluid technology and combined with the advanced technology and experience of the inside and outside of the country. The series of product is a Chinese aerospace and petrochemical two groups work together to develop the project, technology leader in the domestic level. Mainly applied to for temperature less than 100 ℃ of crude oil, gasoline, diesel and other petroleum products and other free of impurities, non-corrosive media.

The design and manufacturing process meet GB/T3215-2007(exactly the same as the American Petroleum Institute API610-2004) "Petroleum, petrochemical and natural gas industries centrifugal" standards

Performance range

   Capacity (Q)：50 ~1000m3/h(the capacity of SDY type pump can reach to 1700 m3/h )
       Head (H)：100 ~1500m

Working pressure（P）：15MPa
   

Structure and characteristics:

1、

DY type pump is horizontal split, single-suction, multi-stage centrifugal pump, impellers arranged symmetrically back to back, the axial force  basic balance structure. Interstage connection adopt internal flowpath and external transition flow.

2、

SDY type pump for horizontal split, double suction first-stage, multi-stage centrifugal pump, impellers arranged symmetrically back to back, the axial force balance structure.

3、

Full three-dimensional design (CAD) combined with advanced flow field analysis (CFD) and strength analysis (CAE), the pump's reasonable structure, small size and high efficiency design goals.

4、

Rotor parts adopt easy assembly structure, pump disassembly without special tools, the high strength stud between uper and lower pump body was densely design by the 3D simulation optimization to ensure smooth operation of the pump under high pressure, and ensure the open face no leakage.

5、

Inlet and outlet flanges of pump on both sides of pump body, horizontal layout, easy assembly and disassembly.

6、

Volute arranged symmetrically with each other by 180 ° balance furthest radial force, the rotor section has go through rigorous balancing test, ensure that the pump for a long time efficient and smooth operation.

7、

Cartridge mechanical seal structure to ensure reliable sealing, installation and maintenance more convenient. Pipeline of flush seal the hydrocyclone may be provided on flush sesl pipeline , to ensure the cleanliness of the sealing fluid, prolong seal life.

8、

Pump rotor can be supported by rolling ball bearing, also can be supported by bush(ing) bearing.When being supported by bush(ing) bearing, the residue axial force of pump is born by the thrust bearing in the non-driven-end bearing parts.Bearing can adopt self-lubricating or forced feed lubrication mode as required, satisfies the requirement of heavy load high-speed cruising.

9、

Product design meets U.S. API 610 standards, through the authentication of ISO9001 quality certification system.

10、

Turning of pump: see pump from motor direction, pump is the clockwise direction rotation. According to user's needs, also can change turning of pump into counterclockwise rotation (adding " -L " in the pump type).

11、

According to user needs, DY pump can be configured to a variety of control sensors (temperature, leakage, vibration), to achieve remote monitoring.

Application:

It can be widely used in oil products, crude oil and other long-distance pipeline custody transfer, oil gathering stations, oil refinery, oil storage and terminal of each delivery and handling of crude oil, refined oil and residual oil, can also be used for conveying water and physical and chemical properties similar to water other liquids. Media viscosity ≤700mm2 / s, crude oil no containing solid particles, water and other products.

Demonstration of the type
the type of Horizontal split oil transportation centrifugal pump is made up of capacity, head and pattern characteristic, according to the following statement:
