Traditionally, vertical column pumps have been used to handle livestock effluent, but a recent trend in Victoria shows dairies switching to submersible cutter pumps to eliminate clogs. We look at how one farm has made the change.
Managing effluent efficiently on a dairy is paramount for animal health and welfare. The waste is often contaminated with solids and standard pumps are prone to blockage and failures.
Ashley Mezenberg manages a 400-head dairy herd South of Traralgon Victoria. The effluent collected from his Herringbone feed pad is laden with solids material. When faced with repeated vertical column pump failures, he changed over to a Tsurumi submersible cutter pump supplied by Aussie Pumps’ Gold Distributor Rodwells.
Tsurumi, the world’s leader in submersible pump development, has produced a range of cutter pumps, called the C Series, designed to handle such contaminated waste. The C series cutter pumps chop waste material thus allowing free passage through the pump without clogging.
“Tsurumi’s breakthrough cutter impeller chops through sewage, straw, plastic, rags and other materials in seconds,” said Aussie Pumps Product Manager Neil Bennett. “We’ve seen various unmentionables handled by these extraordinary pumps so they were an obvious choice for the dairy collection pit,” he said.
The C Series incorporates a large open channel impeller with a cutter mechanism. A sintered tungsten carbide alloy tip is brazed on the impeller vane. As the impeller rotates the vane slices against the serrated edge of the suction cover, chopping fibrous matter into small fragments that won’t clog.
The 3 phase, heavy duty pumps range from a 50mm to a 100mm bore. The largest pump in the range has an enormous capacity of 2,750 litres per minute, and a maximum head of 26 metres.
Like all Tsurumi submersible pumps, the C Series include features that extend the life and enhance reliability of the pump. Significant design details make a big difference. These include anti-wicking cables and silicon carbide seals.
Ashley has reported that the Tsurumi submersible cutter pump is working well and that he is happy with the pump selection and performance.
