Product Overview
Industrial pressure boosting and groundwater extraction require pumps that handle high flow rates with consistent pressure. The Lowara 4ZN616/4-3 submersible pump delivers 48.9 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 provides mechanical integrity for demanding borehole applications.
The engineering details translate into reliable operation. AISI 316 stainless steel resists corrosion from aggressive groundwater chemistry, extending service life and reducing maintenance costs. The stainless steel impeller incorporates a removable wear ring, while the suction strainer limits sand ingress to 100 grams per cubic metre. The replaceable coupling allows for maintenance without full pump extraction.
Powered by a 3 kW three-phase motor at 415V, the pump draws 7.64 Amps and achieves 367 L/Min maximum flow. Shut-off head reaches 48.9 metres, with the 65 mm discharge outlet accommodating standard pipework. Performance complies with EN ISO 9906 Grade 3B tolerances.
Class F insulation and IP68 rating support immersion up to 300 metres. The Duplex stainless steel shaft, AISI 316L tie rods, and NEMA-compatible coupling ensure long-term reliability. The unit meets ErP ecodesign standards.
