Pro-Flo® SHIFT Series - The Premium Air Distribution System (ADS) for Air-Operated Double-Diaphragm (AODD) Pumps

Wilden Pro-Flo Shift FAQ

• How much energy does the Pro-Flo SHIFT Series AODD Pump save compared to other diaphragm pumps?

  Wilden Pro-Flo SHIFT Series Air-Operated Double-Diaphragm (AODD) Pumps eliminate air chamber overfilling and optimize air consumption without reducing the flow rate. This achieves up to 60% in air savings, significantly reducing operating costs, making the Pro-Flo SHIFT Series one of the most energy-efficient pump technologies for industrial fluid transfer applications.

• Do Pro-Flo SHIFT Series AODD Pumps stall during operation?

  No. Pro-Flo SHIFT Series Air-Operated Double-Diaphragm (AODD) Pumps use an unbalanced spool in the air valve to prevent stalling.

• Can Pro-Flo SHIFT Series AODD Pumps run dry safely without damage?

  Yes. Wilden Pro-Flo SHIFT Series Air-Operated Double-Diaphragm (AODD) Pumps can run dry without significant damage. This dry-run capability is ideal for applications involving variable or interrupted flow processes. Additionally, this feature helps the Pro-Flo SHIFT Series self-prime. However, it is important to note that dry runs will still cause wear on the diaphragms, and excessive dry runs could eventually lead to diaphragm failure at higher cycle rates.

• Are Pro-Flo SHIFT Series AODD Pumps suitable for 24/7 continuous use?

  Yes. Wilden Pro-Flo SHIFT Air-Operated Double-Diaphragm (AODD) Pumps can be used in continuous, 24/7 operation. Its reliability in round-the-clock use makes it a top choice for demanding process and manufacturing environments. A key feature of the Pro-Flo SHIFT Series is its superior air efficiency, the highest on the market, which translates to reduced energy costs compared to competing pumps, especially in applications requiring long-duration operation.

• How does the Pro-Flo SHIFT Air Distribution System (ADS) improve air efficiency in AODD pumps?

  Wilden Pro-Flo SHIFT Air-Operated Double-Diaphragm (AODD) Pumps are engineered to restrict the air flow into the air chamber as each pump stroke nears completion, ensuring just enough air is introduced to sustain the pumping process. This technology reduces air consumption per cycle, improving pump efficiency for facilities focused on sustainability and cost control.
