Mini pump with two diaphragms MIDGETBOX has a polypropylene PP casing. The pneumatic mini pump MIDGETBOX can be used in harsh industrial conditions, in hazardous areas, for pumping liquids. The pump capacity reaches 5 l / min, the maximum height of the liquid column in self-priming mode is 4 meters. They work stably even in the presence of insoluble solids in the working substance. The performance of the equipment is adjustable by the user in the range from 0 to 100% without pressure loss. This pump is powered by a compressor, pneumatic line

  • little weight, compact dimensions, easy maintenance

Performance Graph

MIDGETBOX MINI PNEUMATIC DOUBLE DIAPHRAGM PUMPS


This figure shows the dependence of the head and pump capacity on the pressure and air flow of the compressor. The higher the compressed air pressure, the greater the head and the higher the performance curve, in turn, the speed of pumping liquid is regulated by changing the air flow

For example, at a pressure of 5 bar, the optimal operating mode will be pumping of 3 l / min with a head of 25 meters, the air flow will be 40 nL / min.
