Yamada Air Operated Double

nnDIAPHRAGM PUMPS

These pumps are lightweight,compact and easy to use forpumping a wide range of liquids.As they are air operated
they are ideal for pumping volatile or inflammable liquids in
hazardous areas.Self-priming from a dry start these pumps are ideal insituations where liquid has to be pulled from a container.
The pumps can also run dry.The robust construction reduces maintenance to aminimum. >

nnDIMENSIONSPerformance Curves

Performance curves and test data are based on fresh water at ambient temperature.Discharge volume and headvary according to viscosity,specific gravity and other physical properties of the fluid/paste being pumped. To achieve the best diaphragm life and the most efficient air consumption,select a pump 1.5 times the required
capacity. >
