동공이송식 펌프 제조업체인 NOV Mono사가 뉴질랜드 폭스턴 시의 Castle Glen 농장에 동공이송식 펌프를 제공했다. 이 농장은 멀리 떨어진 지역으로 동물 배설물을 이송시키기 위한 노력의 일환으로 많은 원심펌프(centrifugal pump)를 교체할 예정이다.

농장은 이전까지 돼지, 소, 양의 배설물을 관개에 사용하기 위해 3.7㎞ 떨어진 지역으로 옮기는 데 지름 4인치 규모의 많은 원심펌프를 사용해왔다.

 

 

 

NOV Mono, a progressing cavity pump manufacturer, has provided a Mono progressing cavity pump to Castle Glen Farms in the town of Foxton, New Zealand, that will replace a number of centrifugal pumps in an effort to transfer animal effluent over considerable distances. The farms had previously been using a number of different centrifugal pumps to deliver pig, cow and sheep effluent through a 4-inch-diameter pipe, over a distance of 3.7 km to be used for irrigation.

 

"Replacing these with a single Mono pump has allowed us to supply several irrigators, which are located over the length of the pipework, and still deliver the same pressure and flow rate at every nozzle, while also reducing our energy costs," said Castle Glen's Rob Mather. "We were also able to use our existing power supply and not have to upgrade the transformer to cope with a different power requirement."

 

The pump chosen was the Mono Epsilon E1AD, operating at 12 bar and 120 RPM and delivering 35 cubic meters of effluent each hour. These pumps offer proven solutions for this type of application and are designed to create significant cost savings by allowing the use of small-bore pipework when pumping over long distances or with high-head requirements.

 

Accordingly, the pumps can be used for many different types of duty including domestic, industrial and agricultural effluents, industrial chemicals and detergents, mine dewatering, crude oil, and starch slurries. Their smooth progressing cavity action also makes them ideal for handling shear-sensitive substances such as emulsions.

 

The Epsilon pumps also feature Mono's Flexishaft drive shaft connection, which eliminates wearing components between the drive-end and pumping element. As no lubrication is required, the likelihood of product contamination is eliminated. A low running speed capability also reduces wear rates and extends both the pumps' maintenance intervals and overall working life. Available in cast iron or stainless steel, they also offer a choice of rotor and stator materials, which further extend their versatility.
