Designing and building pump sets
The company NDS, designed and created a set of pump sets based on Grundfos multistage centrifugal pumps. The unit was established at the request of Kórnik Enterprises Agri-Trade and Service JAGROL Sp. of o.o. of Pierzchnia. The Company manages the area of 1630 hectares and specializes in the cultivation of potatoes for the chips and fries. This plant is grown on about 300 ha and requires precise irrigation.
What prompted investors to buy the pump?
Decided by economic reasons, as previously used for irrigation of crops was a pump, driven by the tractor's PTO. During the conduct of these operations the pump had to be secured with the tractor and the man operating the system, and the company bore the cost of increasingly expensive fuel consumption. A new set consists of two multi-impeller pumps Grundfos CR, powered by electric motors. Pumps suck water from the tank and press it into the irrigation system. Service system is periodic, which means that it practically does not have direct manual worker. In this farm the pump set supports three sprinklers, irrigating potato plantations.
In modern pumps manufacturer installed CR LiqTec system to control the presence of liquid in the pump, which protects it from the dry running. The sensor of this system is in the pump head, close to the shaft seal, and the electronic control unit is mounted in the outer cabinet. Multistage centrifugal pumps Grundfos CR has unique cartridge seal, which is very durable and easy to replace. This shaft seal is also used in the pump, fully made of titanium, designed for operation in extremely aggressive environments. The pump impeller is installed welded stainless steel with a special design that significantly reduces the formation of the inner turbulence of flowing liquid. Limitation of this phenomenon very much extends pump life. Prepared pump set can be operated in a pressure range of 4 to 20 at, however, the pressure used in this farm is 12-15 at. Press height of liquid through the set is at 120m.
