Selection of high-temperature medium pumps or provision of solutions
Thread Content
Several pumps are required for a new project, with the following operating conditions: Operating temperature: 390°C; Rated head: 120 m; Inlet pressure: 0.5 MPa; Outlet pressure: 3.33 MPa; Flow rate: 2.5 m3/h; Medium viscosity: 1.83 mPaS. Could you please help select suitable equipment? Thank you!
What specific medium? Water, oil,. . . .
A reciprocating pump + remote pump head should work; it’s advisable to use cooling water so that the pipes for transmitting the fluid can be shorter. However, if low pulsation and a small size are required, this approach won’t suffice.
High-stage pumps can be used, but they need to be customized; otherwise, such pumps do not exist
Low flow rate, yet such a high head – what the hell?
Someone upstairs actually said to use a reciprocating pump with a remote pump head? ? ? 390 degrees! ! ! ! Have you ever used a reciprocating (diaphragm) pump under such operating conditions? ? ? At such high temperatures, I only know that Brown Ruby might be able to do it; I need to check the options first, but it will still cost an exorbitant amount! ! 1. Centrifugal pumps are one option; you can consider imported brands or large domestic manufacturers, preferably those of a higher tier than Deep Blue. The medium flow rate and pressure are fine; temperature is the major issue. External flushing along with a series connection for the mechanical seal is definitely necessary. The plan is Plan 32+54, but further discussion with the manufacturer is needed. 2. Screw pumps: In China, Jiangxi Xinde is capable of manufacturing them under these operating conditions, as their rotation speed is lower than that of centrifugal pumps; for seal systems, a self-cleaning design with an oil station similar to the Plan54 scheme can be used. Regardless of the choice, the material is key, so be sure to choose a reputable brand manufacturer!
