Installation And Start-Up
Locate the pump as close to the product being pumped as possible. Keep the suction line length and number of ttings to a minimum. Do not reduce the suction line
diameter.
Air Supply
Connect the pump air inlet to an air supply with sufcient 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 ow as desired. If opening the valve
increases cycling rate, but does not increase the rate of ow, cavitation has occurred. The valve should be closed slightly to obtain the most efcient air ow to pump
ow ratio.
