The COMPACT POPPET STYLE CHECK VALVE fits into drum alarms to serve as a foot valve to prevent backflow.
ALL PLASTIC CHECK VALVE
The check valve is not essential, but for pumps that are difficult to prime like diaphragm pumps, it eliminates having to re-prime the pump when the Drumalarm is withdrawn from the working drum. Also prevents the volume of the suction pipe from backwashing into the drum regardless of the type of pump used.
The liquid flow pushes the elastomer cone part upwards to create enough space for liquid flow.
If you order a check valve along with a drumalarm, we install if for your. If you are installing on after the fact, you should know that all our drumalarms, IBC alarms and suction pipes are pre-machined to accept this check valve.
The check valve inserts into any drum alarm by unscrewing the screen fitting and inserting the poppet valve, special fitting, and o-ring. See the video below for details on installing a check valve on an existing drumalarm.
Optional check valve 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.
