Custom Drum Alarm with 3 suction pipes
Custom Drum Alarm with 4 pipes


In the past we have split the output from a single ¾” pipe into 3 different pumps. (see the manifold drum alarm)  However in this case the pumps are larger diaphragm pumps that created such a high suction force that pumps could starve each other and change the flowrate. Therefore the solution was to separate the suction lines so each pump had its own pipe. Because the drum bung diameter is limited, the maximum pipe size was  ½”.  Each pipe has a check valve inside.




is controlled by the level. When the level gets low in the drum, the level is automatically shut off. This is an extremely low power valve designed to emit a very low heat output made by NACOM Valves.  This valve was selected for use in a non-hazardous area but nonetheless had some flammable solvents.

Also has a battery backup so an alarm is given even during a power failure.


DRUMALARM WITH MANIFOLD for feeding multiple processes from the same drum.

This particular unit in the picture is equipped with a check valve at the button of the suction pipe so priming shouldn’t be necessary. Nevertheless, there is a threaded plug at the top for conveniently priming pumps if necessary.

DRUMALARM WITH SWIVELING PLUG for a customer with drums having extremely domed tops. The curvature of the dome caused the standard drumalarms to point to the middle of the drums which made extracting the last residue of chemical iimpossible. The 10º angle of this design allows the operator to point the drumalarm pipes to the corner of the tilted drums, allowing extraction of the last residues.

After the drum plug is secured to the drum, the operator is able to rotate the drumalarm pipes freely to the best position.

SCREENED FLOAT GUARD keeps debris away from the float. This guard allows level alarms to be used with surpisingly dirty liquids – like black water in port-a-potties. Even though large objects may press against the screen, the liquid will find its way to the float like groundwater flowing through soil.

DRUMALARM WITH A DOUBLE FLOAT provides two alarms: the upper float causes the LED and buzzer to pulse slowly. This alarm can be silenced. Then when the bottom float is triggered, a rapid beeping and flashing occurs to distinguish between the alarms. This provides an early warning to the operator to ready a new drum of chemicals.

Stainless steel liquid level alarm for drum


MINIATURE LEVEL PROBE for a small proprietary bottle. Maximum O.D.of the float is only 16 mm. [0.63″]

VAPOR RETURN LINE for noxious chemicals to eliminate fugitive emmisions.

1 GALLON BOTTLE ALARM with very small suction line..

VERY LOW HEADROOM required this level alarm with a 90º head. Aluminum conduit body and Stainless steel pipe, float switch and removable guard. This is designed for filling rail cars where drops to the ground are a way of life.

CUSTOM DRUM PLUG sent to us from our customer ahd a female buttress thread. We modified it with our plastic fusion process to create the drumalarm which is close to our DHB model.
