I need expert advice: how many distillation pumps should I choose?
Thread Content
I seek guidance from experts. I need to purchase several heat pumps for use in distillation processes. The original pumps were Mitsubishi’s canned motor pumps, but due to cavitation and the high viscosity of the material, these pumps often broke down, so centrifugal pumps are required as a replacement. I would appreciate it if experts could advise me on what type of seal flushing scheme is suitable for such process conditions Which chemical pump manufacturers in the Shandong region (or Dalian) are reliable? Thank you. https://bbs.hcbbs.com/forum.php?mod=image&aid=1992219&size=300x300&key=d2e56410e16aee0f&nocache=yes&type=fixnone https://bbs.hcbbs.com/forum.php?mod=image&aid=1992220&size=300x300&key=8030989f180ac7c6&nocache=yes&type=fixnone
An underwater magnetic pump is a suitable choice; the pump body is submerged in the medium, which means the pump has a pump chamber that can help maintain temperature
Viscous media generally have low saturated vapor pressures and are not easy to vaporize. Can the medium viscosity and saturated vapor pressure be provided at a temperature of 150-160 degrees Celsius?
The Dalian Huanyou and Dalian Empire shield pumps will work
The problem with the Dalian Empire shielded electric pump can be resolved.
This problem can be solved with a centrifugal pump; add WeChat 13738157326 for further discussion
These substances are not viscous; it’s not a problem of viscosity but rather an issue related to the installation height. In other words, the pump does not have sufficient net positive suction head. The solution is to install a cooling heat exchanger at the inlet, or to increase the pump’s net positive suction head
