High-speed pump questionnaire
Thread Content
I am currently working on a project related to high-speed pumps, and I would like to understand the market demand, especially from refineries and similar facilities. Dear experts and seniors: Could you provide some basic parameters? 1. Manufacturer: 2. Equipment used in conjunction with it (e.g., propylene recycling unit, molecular sieve degreasing unit, pre-hydrogenation pump, gas extraction unit, liquid hydrocarbon pump, etc.): 3. Basic parameters: ① Model: ② Structure type: Vertical ( ) Horizontal ( ) ③ Flow rate Q= ④ Head H= ⑤ Rotational speed n= ⑥ Required NPSHr = ⑦ NPSHa of the unit = ⑧ Shaft power N= Motor power P= ⑨ Medium to be transported: Medium temperature: Medium density: ⑩ Pressure in the inlet pipeline or pressure vessel: Diameter of the inlet pipeline: Maximum operating pressure: If you think there are too many parameters and you can’t remember some of them. Provide flow rate Q, head H, and rotational speed n – that’s all! Of course, the more detailed the parameters, the better. Thank you! This post was last edited by lxzzl on 2008-7-23 12:38.]
Vertical high-speed pump – can you manufacture it? CAPACITY: NORMAL 18 (m3/h); SUGGESTED SUCTION PRESSURE: 200 kPa(g); DIFFERENTIAL HEAD: 1600 (m); NPSHA: 8 (m). As far as we know, the only company in China that is good at manufacturing such pumps is Aerospace Institute No. 11
We use the one from the 11th Aerospace Research Institute. There are vertical and horizontal types. Liquefied gas medium. GSB-W3-36/350: Q=32.9 m3/h; H=370 M; n=9818 revolutions per minute. Last edited by lxzzl on 2008-7-23 15:33.]

ACSS-11, Beijing Cruise High Technology, and Jarite Ebara – all three are capable of doing it
The methanol gas processing unit at Shanxi Fengxi Linyi Company uses high-speed pumps manufactured by Beijing Institute 11; the specific model parameters are not known.
High-speed pumps generally have a power rating of 75 kW or less, with a rotational speed of around 10,000 rpm; vertical types are preferred over horizontal ones. Currently, Sundyne pumps imported from abroad are widely used in China; they are of good quality but expensive. The best pumps produced in China come from Institute 11, Jialiite also offers good products, and Zhejiang Tiande manufactures pumps with lower power ratings as well.
1. Manufacturer: Jialiite 2. Applications and associated equipment (e.g., propylene recycling unit, molecular sieve degreasing unit, pre-hydrogenation pump, gas extraction unit, liquid hydrocarbon pump, etc.): Hydrogenation of refinery diesel 3. Basic parameters: ① Model: LG222-16/948-132-172ⅢDT ② Structure type: Vertical ③ Flow rate Q=14 m3/hr ④ Head H=948 m ⑤ Rotational speed n=17200; Shaft power N=108.4 kW; Motor power P=138 kW. Transport medium: Demineralized water; Medium temperature: 38°C; Medium density: 1; Pressure in inlet pipeline or pressure vessel: 0.4 MPa; Diameter of inlet pipeline: 80 mm; Maximum operating pressure: 12 MPa
