For easy transport around the mine, these Wilden 3 inch pumps were mounted on roll frames.
In hazardous and explosive environments, such as mines, electricity is usually not supplied as it is potentially risky and unsafe. Remote sites also do not have any power supply as it is cost inefficient to do so.
All these factors made it hard to pump fluid using traditional pumps such as centrifugal pumps or gear pumps. Fortunately, Air-Operated Double-Diaphragm (AODD) pumps usually work well under these conditions.
All Pumps supplied Wilden T20 3 inch cast iron pumps to a mining. The AOD pumps were mounted on roll frames for easy transport. The pumps also have a max flow rate of 1040Lpm, suitable for many work around the site.
