Product Overview
Groundwater lowering and high-volume irrigation systems need pumps that deliver reliable performance under continuous operation. The Lowara 4ZN616/5-3 submersible pump delivers 61.1 metres of shut-off head, featuring a 6-inch AISI 316 stainless steel wet end with 4-inch motor connection. Its microcast stainless steel construction ensures durability for demanding borehole applications.
The material selection directly impacts operational lifespan. AISI 316 stainless steel resists corrosion from aggressive groundwater, reducing the risk of premature failure. The stainless steel impeller with removable wear ring handles suspended solids up to 100 grams per cubic metre, while the integrated suction strainer protects internal clearances. The replaceable coupling simplifies maintenance without pump removal.
Driven by a 4 kW three-phase motor at 415V, the pump draws 10.2 Amps and delivers 367 L/Min maximum flow. Shut-off head reaches 61.1 metres, with the 65 mm discharge port connecting to standard pipework. Performance complies with EN ISO 9906 Grade 3B tolerances.
Immersion depths up to 300 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.
