The DRUM SUCTION PIPE draws chemical from the bottom of your drum to eliminate pumping air.

DRUM SUCTION PIPE
DP-P-55G (WITH FLOWMETER)
A BETTER WAY TO FEED CHEMICALS
  • The rigid polypropylene pipe can be adjusted so it always reaches the bottom of your drum for perfect flow without pumps becoming air locked.
  • Drums are pumped out nearly completely which will reducing wasted residual chemical.
  • There is a built-in suction screen to keep particles/debris/crystals out of your pump. This screen is replaceable.
  • Included compression fitting accommodates any tubing size from 1/4″ to 3/4″ tubing O.D.
  • Optional acrylic flow indicator lets you conveniently monitor the flow.
  • Optional check valve available.
  • Adjustable depth
 

The Drum Suction Pipe, pickup tube, or draw tube, is the best way to extract chemicals from drums because they solve the problems with dangling a plastic flexible tubing into a drum.  Often the tubing is inserted so it doesn’t reach down to the liquid at the bottom of the drum, which results in the pump drawing air.  Or the tubing loses it plasticizers over time and cracks, or curls up, which again causes the pump to draw air. Of course you get no warning when this happens. 

We offer different suction pipes built specifically for the task of drawing chemicals from drums.  Choice of 2″NPT thread (most common) or 2″ Buttress thread (the coarse thread which requires fewer turns to screw in) or for the 3/4″ bung on metal drums we offer a 3/4″ NPT thread.  Further discussion on drum threads here.

Also a choice of materials: polypropylene is most common but Kynar and 316 stainless steel are available for applications that require it.

NOTE ON MODELS

The models that fit into 2 inch bungs (DP and DB models) use a 3/4″ pipe which allows a larger foot-screen area at the bottom.  The 3/4″ NPS mount (DK) uses a 1/2″ pipe which is the maximum that can fit into a 3/4″ NPT thread of the drum.

CHECK VALVE

A check valve is a common accessory for our suction pipes.  It eliminates re-priming the pump when transferring the suction pipe to a new drum.  This is not a must for self-priming pumps like bellows or peristaltic, but even for these pumps it stops the residue of chemical in the pipe from backwashing into the empty drum.  more info

A better way to prop up your drum so you can extract the last residue. Sure a block of wood could do the trick but will your customers be impressed by it during factory inspections?

Check Valve

Optional check valve  f  for use with diaphragm pumps, it stops the liquid from draining out of the feeding pipe during transfer to a new container. Eliminates re-priming pump. See YouTube video here.
