Warren Rupp introduces the AirVantage air-operated double diaphragm (AODD) pump. The pump is designed to reduce energy costs by cutting air consumption at the pump, and it automatically adjusts as process conditions change to maintain constant flow without manual operation or adjustment.

Beta tests and field trials have shown that AirVantage provides up to 50% energy savings compared to traditional AODD pumps, according to Warren Rupp. The pumps are available in 2-inch and 3-inch sizes under Sandpiper and Versa-Matic brand names.

This new technology is designed to reduce air consumption and save energy by cutting the amount of air volume needed per diaphragm stroke. The diaphragm is able to operate at full stroke with reduced air volume (SCFM) while sustaining desired stroke rate and fluid flow.

AODD pumps with this technology are equipped with a microprocessor that is adaptive and continuously manages the amount of air volume required to operate the pump at desired flow rates. This adaptive technology determines the optimal diaphragm rod velocity and relays the information to an air distribution valve at the air inlet location of the pump. The valve acts as a gated air management system, allowing only enough air to enter each inner pump chamber.
