Product introduction
ASP5350 series heavy-duty oil chemical process pump series horizontal multi-stage centrifugal pump, horizontal center line support, horizontal multi-stage centrifugal pump with double shell, section and impeller. According to the standard of API 610, "centrifugal pump for petroleum, heavy chemical and natural gas industry". The first stage impeller can be designed as single or double - suction structure according to user requirements.
Sealing system completely according to API682 second edition of the centrifugal pump and the rotary pump shaft seal system design, with various forms of sealing and flushing cooling scheme, suitable for all kinds of complicated conditions, wide use.
Range of application
It is mainly used to transport oil, refined oil, liquefied petroleum gas, light hydrocarbon, boiler feed water and other clean or contain micro-particles, flammable and explosive, toxic media.
The typical working conditions are used for the hydrogen-feeding pump in the heavy oil hydrogenation unit of the refinery, the high pressure coke removal pump and the power plant of the steel plant in the removal of the pyrophosphate in the plant.

Product structure characteristics
1、Reloading the pump body:
(1)The pump body is designed according to the maximum allowable working pressure, and the import and export can carry double API load. (2) all flanges are designed according to maximum allowable work pressure, including sealing system pipeline;
(3)Bolt coupling flanges are standard and other connection modes are optional.
(4)The standard import and export flanges are top and top, and can also be used for side or bottom import and export.
(5)Center support, and can improve the thermal stability and increase the nozzle load, casting cylinder, import and export of the flange and the cylinder integral casting, forging cylinder, import and export of the flange and the cylinder body welding, NDE inspection and for temperature greater than 260 ° C high temperature medium need warm pump system, through the residual liquid mouth cylinder, the transmission of high temperature medium, the need to provide positioning and orientation, can be equipped with isolation layer or reduce noise shield;
2、High stability rotor
(1)Optimum shaft diameter and bearing span ratio;
(2)Dynamic rigid design ensures high critical speed and low static disturbance;
(3)Ensure high stability, high speed and long service life;
(4)The large diameter axis world, low stress design, all mechanical processing, the overall rotor dynamic balance, the coupling shaft of the coupling is cylindrical or conical, or hydraulic coupler, meet the API610 standard;
3、Easy to maintain: the core pack can be pulled out of the shell without disassembling the bearing, sealing and the main line. Remove the tools used to provide the user with standard configuration 。
4、The monitoring of the pump
(1)Standard configuration includes temperature and vibration monitoring of key components;
(2)Connection of terminal box or control panel;
5、Precision casting impeller
(1)Static and dynamic balance;
(2)Comply with API 610 requirements to ensure optimum vibration characteristics;
(3)The impeller and axis overmatched, single axial fixation;
6、Bearing housing
(1)The bearing box can be split up and down, ensuring the mechanical seal and bearing's disassembly is convenient ;
(2)The material is cast steel, finish machining;
(3)360° The circular fixed rotor provides optimum support and reduces vibration;
(4)Seal seal;
7、Optimum hydraulic performance
(1)All hydraulic performances are tested by a large number of practices;
(2)The casting impeller ensures the design effect;
(3)The first stage impeller adopts low suction ratio speed standard design. The large size pump can double suction at the head level, which can improve the cavitation resistance ;
8、Mechanical seal
(1)The standard configuration is set type mechanical seal (single end or double face);
(2)API682 standard sealing cavity guarantees the versatility of mechanical seal life and mechanical seal.
(3)Saving investment cost;
(4)Long sealing life;
Optional material configuration
S-5、S-6、S-8、C-6、A-7-1、A-8-1、A-8-2、D-1
Note: different materials can be used according to the actual condition
