Are there high-pressure slurry pumps that don’t require water cooling?
Thread Content
With a pressure of 15 MP and a slurry that tends to crystallize, at a temperature of 90–100°, which high-pressure pump can operate properly for extended periods without water cooling? (Mainly for environmental reasons, water cannot be used!) ）
What is the solid content? How much is the traffic? Can I choose a pump without a seal, such as a diaphragm pump or something like that?
It is a neutralizing solution with high viscosity; the flow rate is approximately 13 m3/h. It has no solid content but tends to crystallize easily
With a mechanical diaphragm pump or plunger pump, cooling water shouldn’t be required, right?
Without cooling water, the packing started leaking material after a short while
You can consider flushing schemes for mechanical seal cooling, such as Plan53A, Plan54, and so on
Filler leakage is probably due to the material crystallizing in areas with low temperatures; without water for flushing, this causes wear on the filler. At this temperature and pressure, various fillers can meet the application requirements; in such cases, insulation is more effective than water flushing.
It was operated for a few days without water cooling; the neutralization solution turned into a powder, and then the filler leaked
The neutralizing solution was dried after high-temperature friction
A high-pressure diaphragm pump would work; it is a sealless pump. However, the cost associated with its flow rate and pressure is too high
I think high-temperature and high-pressure plunger pumps should be able to meet such requirements
