Lowara, part of the ITT Industries Group, has introduced a new submersible pump made of stainless steel that it believes will deliver higher performance, energy savings and lower running costs. The ZN8 pumps have an 8" diameter, flow-rates up to 180 m3/h and heads up to 550 m, meaning that the pumps can be used in aqueducts for supplying drinking water, in water pressurisation and distribution installations for civil and industrial use, and in irrigation systems for farms and large green areas such as parks and golf courses. They can also be installed in fountains, in pumping systems for fish farms, in water supply systems from deep wells and last but not least, for dewatering in civil engineering and mining installations. The main pump components are made of precision-cast AISI 316 stainless steel, a material with high mechanical strength which makes it possible with minimum wall thickness to obtain the same performance as traditional materials. For this reason ZN8 pumps are lighter and therefore easier to transport and especially to install. The critical components such as the shaft, conical locking sleeve and pump coupling are made of duplex stainless steel, a material which is highly resistant to corrosion.
