Onga centrifugal pump range
Onga has the 400 series, 12 series, 18 series, 14 series and the Blazemaster firefighter range of centrifugal pumps. These are all designed for a wide range of applications across domestic, agriculture and industry. These are 1 and 2 stage centrifugal pumps with both electic and petrol motors designed for water transfer, washdown and irrigation. They come in a range of nominal flow rates from 100L/min up to 800L/min in 125-425 kpa pressure. These pumps aren’t designed to be run with automatic pressure control due to their higher volume and low pressure differential. We stock mechanical seals, bearings, O-rings and capacitors for the entire centrifugal range.
