REQUIRED WINTERIZATION FOR PUMP
(OP)
Hello guys,
I have a question, how do vendor winterize a pump? This pump is an AODD pump.
Thank you and hope to get some response from you.

RE: REQUIRED WINTERIZATION FOR PUMP
If you want to winterize it and leave it in a non-operating condition, there might be enough drain plugs that you can remove to get the liquid out and enough vent plugs to let some air in, so you can drain every chamber. ... which on an AODD could be quite a lot of work.
If you need the pump to be operable in winter, or you don't want to bother with a lot of plugging and unplugging, you could build an insulated box around the entire assembly, and put a suitable heater in the box. If the flow is high or the winters get cold where you are, you may need a pretty big heater. Also build in an appropriate louver so the exhaust air can get out of the box without too much snow getting in.

1) how do you leave a pump in the winter not operating?
OR
2) how do you maintain opearability in "winter" conditions.
Either way what is "winter" (how low does it go?) and what are you pumping?
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

LitteInch --- I meant the (2). Referring to P&ID this AODD will be installed outdoor ( i don;t know yet if location will change though). It will be installed in OHIO and it will be pumping condensate (mixture of water or hydrocarbon).
I don't understand why we have to drain the pump, is this related to pump operability in winter conditions? Please enlighten me.
Thanks,

To winterize the pump, install self limiting heat tape and insulate. On alternative is a cellular glass insulation that will drain and not absorb hydrocarbons. Insulation will need to be jacketed for protection.

If you have steam available, you may heat trace with steam. The pump will have to compatible with steam temperatures.
An alternative to insulation is an insulation blanket. It should be fireproof.
