Pump in Acetone service - Seal requirements

[Fudian82]

Hello, we are currently checking for the min. requirements for pump seal requirements. The pumps in our project are in these operating ranges:
[ul]
[li]Acetone: 90 wt% / T_op: ~10 °C / P_op: 6 barg[/li]
[li]Acetone: 80-100 wt% / T_op: 45 °C / P_op: 2 barg[/li]
[li]Acetone: 60-80 wt% / T_op: 100-120 °C / P_op: 3-5 barg[/li]
[li]Acetone: 20-60 wt% / T_op: ~60 °C / P_op: 3-5 barg[/li]
[/ul]

Which type of pump sealing for centrifugal pumps do you recommend? Or have to go for some pumps to sealless?

Opt1 Double packing with constant washing by water of a chamber between them, washing fluid pressure shall be higher than that of liquid pumped.
Opt2 Single packing with a drip pan + local exhaust ventilation + constant supervision by a responsible worker

Contact a reputable seal manufacturer / supplier.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Depends on the amount of soilds, but a mag pump seems like a good alternative. You dont want your boiling 80% acetone to leak too much
