Installation And Start-Up

 

Locate the pump as close to the product being pumped as possible. Keep the suction line length and number of fittings to a minimum. Do not reduce the suction line 

diameter .

Air Supply

 

Connect the pump air inlet to an air supply with sufficient capacity and pressure to achieve desired performance. A pressure regulating valve should be installed to 

insure air supply pressure does not exceed recommended limits.

Air Valve Lubrication

 

The air distribution system is designed to operate WITHOUT lubrication . This is the standard mode of operation . If lubrication is desired, install an air line lubricator 

set to deliver one drop of SAE 10 non-detergent oil for every 20 SCFM (9 .4 liters/sec .) of air the pump consumes . Consult the Performance Curve to determine air 

consumption .

Air Line Moisture

 

Water in the compressed air supply may cause icing or freezing of the exhaust air, causing the pump to cycle erratically or stop operating. Water in the air supply can 

be reduced by using a point-of-use air dryer .

Air Inlet And Priming

 

To start the pump, slightly open the air shut-off valve. After the pump primes, the air valve can be opened to increase air flow as desired. If opening the valve 

increases cycling rate, but does not increase the rate of flow, cavitation has occurred. The valve should be closed slightly to obtain the most efficient air flow to pump 

flow ratio.
