Product Overview
Dedicated waterworks and high-head irrigation systems need pumps that deliver consistent pressure under varying demand. The Lowara ZN612/12-3N meets these requirements with its 6-inch AISI 316 stainless steel wet end and radial flow impeller design. The microcast stainless steel construction provides durability for continuous submersion in borehole applications.
The engineering behind this pump focuses on long-term reliability. AISI 316 stainless steel resists corrosion from aggressive groundwater chemistry, while the stainless steel impeller with removable wear ring handles suspended solids up to 100 grams per cubic metre. The integrated suction strainer protects internal components, and the replaceable coupling simplifies maintenance, reducing service time and costs.
Powered by a 7.5 kW three-phase motor at 415V, the pump draws 17 Amps and delivers 275 L/Min maximum flow. Shut-off head extends to 136.1 metres, with the 65 mm discharge port connecting to standard pipework. Performance complies with EN ISO 9906 Grade 3B tolerances.
Immersion depths up to 350 metres are supported by Class F insulation and IP68 enclosure rating. The Duplex stainless steel shaft, AISI 316L tie rods, and NEMA-compatible coupling ensure long-term reliability. The unit meets ErP ecodesign requirements for energy efficiency.
