need a drum pump
(OP)
We need a pneumatic drum pump to pump methylene chloride to top up some tanks on machines.
We tried a couple but they couldn't suck the last few inches from the drum (I'd settle for 1" maximum left in the drum), or worse they siphoned when dispensing to a lower level (a container on the floor) which was "interesting" to watch as people struggled to stop the flow.
We don't need a fast flow rate (had to fit a regulator to the pump to slow it down).
(The diaphragm pump we tried pulsed too violently, causing lots of splashing in the tanks).
So, does anyone know where we should go to get a pump to do what we need (or indeed what type I should look for)
PS We're in the UK.

A double diagphram pump such as the Wilden is probably your best bet. To eliminate the pulsations on the discharge, consider installing a small tank to serve as a reservoir. To drain to the bottom. Fabricate a suction fitting that will suck from a continuous slot along the sides with the bottom closed. The slot area to be the same as your hose i.d.
