ITT Lowara has introduced a new line of stainless steel submersible pumps that are especially designed for high hydraulic efficiency in applications such as water supply from deep wells, pressure boosting and water distribution in civil and industrial systems, water level control, dewatering, fire-fighting and irrigation.
“An extensive use of high-grade materials has ensured high resistance to corrosion and wear in the Z10 and Z12 line of pumps, which are suitable for 10 and 12-inch wells,” says a spokesman for its Italy-based manufacturer. “These qualities also guarantee that the efficiency of the hydraulic performance is maintained over a long period of time.”
“For highly aggressive water environments a full duplex version is also available,” he adds.
The new series with five main sizes covers a wide performance range. The smallest is the Z10150 with 150 cu m per hour nominal flow and the largest is the Z12420 with a nominal flow of 420 cu m per hour. The complete range offers heads up to 545 m and flows up to 520 cu m per hour.
“The hydraulic design, together with investment castings for high surface finish, gives an efficiency that for almost every duty point between 120 cu m per hour and 460 cu m per hour is higher than 80 per cent,” he says.
The high-grade materials used, the strong design and optimal material thickness make the new range competitive against traditional cast iron pumps, the spokesman claims.
“Over time, energy consumption and service are considered to be the main part of the total cost of operation, and the new Z10 and Z12 designed for energy efficiency and long life often prove to be the best solution,” the spokesman states.
With this addition to the ITT Lowara borehole family, the range of stainless steel borehole pumps now spans between 4 inches and 12 inches.
