High Pressure Supply Pumps

250 Type (10 x 1, 20 x 1, 40 x 1, 47 x 1, 55 x 1) for Drum Containers Divorced Pump Unit SR250DWAL series

This pump unit for 200 L drum containers can stably transfer high-viscosity materials with an air-powered pressurized lift.
To suit the material to be transferred, a packing seal type (SR250P□) for grease and a metal seal type (SR250M47) for adhesives and other materials are available.
Air-powered pressurized lifts come standard with a sensor for lower limit detection.
This sensor can be used to prevent the pump from running dry when the pumped material has been depleted. In addition, for the packing seal type (SR250P)□, a perforated plate attached to the bottom of the inductor plate minimizes the amount of material remaining in the drum container.
This allows material to be used without waste until the very end of the pumping process.
