Product Description

Applications
* ldeally suited for intermittent/on-demand, portable moderately abrasive fluids, and suspended solids.
* Simple air distribution system design, minimal moving parts.
* Clamped design for lightweight and quick maintenance.
* AODD pumps can pass even large, shear-sensitive solids without degradation or heat buildup transferred to pumped medium
* AODD pumps are able to run dry without damage to the pump
* Lead time: Normal Stock

Pay attention: Performance data is based on pump testing with water at room temperature. Factors such as different diaphragm materials, ball and seat materials, feeding methods, environment, fluid characteristics, hydraulic conditions, etc., may lead to deviations of more than 5%.

Safety Information
Ambient temperature range: -20°C to +40°C Process temperature range: -20°C to +80°C for models rated as category 1 equipment -20°C to +100°C for models rated as category 2 equipment In addition, the ambient temperature range and the process temperature range do not exceed the operating temperature range of the applied non-metallic parts as listed in the manuals of the pumps.

Installation And Start-Up

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

Air Supply

Connect the pump air inlet to an air supply with sufffcient 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 ffow as desired. If opening the valve increases cycling rate, but does not increase the rate of ffow, cavitation has occurred. The valve should be closed slightly to obtain the most efffcient air ffow to pump ffow ratio.
