P&ID Symbol - Metering Pump
P&ID Symbol - Metering Pump
(OP)
Wonder if anyone can advise as to what the 'proper' P&ID symbol for a metering / dosing pump might be? Struggling to find much on-line but did find the attached link on 'Northridge Pumps' site.
Is this symbol in general use for metering pumps?
(Background is I have a load of clients P&ID's where they've used a centrifugal pump symbol for metering pumps and a correction / update is required).
Many thanks.

I would be tempted to just draw a square box with MP in the middle and a motor attached so that you can turn it on and off or control the speed and then define it in the legend sheet.
Those ISO symbols look Horrible IMHO.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
RE: P&ID Symbol - Metering Pump
But in answer to your question, it would probably be against BS EN ISO 10628. (Although I don't have a copy of that one so I don't know whether 'metering pumps' are categorised in that).
I'm tempted to follow the approach of LittleInch and just 'black box' it. This would be better than the misleading centrifugal pump symbol currently in use.

As you are probably aware, there is no universal standard for preparing a P&ID. Most experienced engineers would probably recognize the application particularly by the pumping characteristics (if you have that on the P&ID) no matter what symbol you use.
