Wilden, an air-operated double-diaphragm (AODD) pump technology developer, has released a new line of natural gas-operated double-diaphragm pumps.
Specifically designed for the oil and gas industry, the pumps have been certified CSA International to be used in applications where natural gas is the energy source to drive the pump.
Well-suited for upstream and midstream oil and gas applications, the new pumps are available in Wilden Original (clamped), Advanced (bolted), and Advanced FIT models.
They come equipped with either the patent-pending Wilden Pro-Flo Shift air distribution system (ADS), which is CSA-certified ANSI LC 6-2008, or the Wilden Pro-Flo X ADS, which is CSA-certified for the ANSI LC 6-2008 and TIL R-14.
The pumps are offered in 13 mm (1/2”) clamped and 25 mm (1”), 38 mm (1-1/2”), 51 mm (2”), and 76 mm (3”) bolted configurations.
Wilden CSA-certified pumps also comply with all CE and ATEX requirements, and feature extreme shear sensitivity, high-viscosity handling, dry-run capability, anti-freezing, and no deadhead damage.
The maximum flow rate is 993lpm for the 76 mm model, and the maximum discharge pressure is 6.9 bar for all models.
Wetted paths are aluminium or stainless steel and available diaphragm materials are Buna-N, PTFE, or Wil-Flex.
