The helical pump is part of a system to distribute the liquid from cattle slurry over farm fields. Although essentially a waste product, the system maximises the fertilising quality of the cattle slurry by spraying the water content over crops and grazing areas.

The system in place removes water from cattle waste and feeds it into the pump, which is mounted in the farmyard. The pump is connected to pulser devices situated in various fields up to 1000m away. The pulser is fitted with a bladder accumulator, which discharges the liquid when the pressure reaches 7.5 bar.

The helical pump was favoured due to its excellent solids handling capabilities, larger cavity size and its self priming ability, enabling the water component of the slurry to be delivered at a constant flow rate.
