New hygienic metal AODD pumps from Wilden

Wilden, part of PSG, a Dover company and a global air-operated double-diaphragm (AODD) pump technology provider, has released the new Saniflo Hygienic series (HS) Original metal AODD pump models.

The new pumps utilise the energy-efficient Pro-Flo Shift air distribution system (ADS).

They comply with EHEDG, 3-A, CE, ATEX, USP Class VI, 1935/2004/EC, and FDA CFR 21.177 requirements for use in a variety of hygienic applications.

Launched in June 2013, the Wilden Pro-Flo Shift ADS allows Wilden Advanced and Original AODD pumps to achieve up to 60% savings in air consumption, while providing more product yield per standard cubic foot per minute (SCFM), Wilden says.

While the Pro-Flo Shift improves energy efficiency, it is submersible and features plug-and- play operation.

Its design makes the Pro-Flo Shift well-suited for use in harsh operating environments and includes ATEX compliance for use in potentially explosive atmospheres.

Using fewer operating parts, the Pro-Flo Shift’s design prevents overfilling to prolong diaphragm life and reduce noise, maintenance, and repair for less downtime and a lower total cost of ownership.

The new Saniflo HS pumps are available in 316 stainless steel and nickel-plated aluminum in 38mm, 51mm, and 76mm sizes and feature maximum discharge pressures to 8.6 bar, maximum flows to 844lpm, and maximum solid-handling size to 60.3mm.

The pumps are available with maximum suction lifts to 5.4m dry and 9.0m wet.
