Product Overview
Dedicated waterworks distribution and high-head irrigation systems need pumps that deliver consistent pressure under varying demand. The Lowara ZN616/21-3 submersible pump delivers 257.8 metres of shut-off head, featuring a 6-inch AISI 316 stainless steel wet end with 6-inch motor connection. Its microcast stainless steel construction provides mechanical integrity for demanding borehole applications.
The material selection translates into operational benefits. AISI 316 stainless steel resists corrosion from aggressive water chemistry, extending service intervals 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 pump removal.
Powered by a 15 kW three-phase motor at 415V, the pump draws 32.1 Amps and achieves 367 L/Min maximum flow. Shut-off head reaches 257.8 metres, with the 65 mm discharge outlet accommodating standard pipework. Performance complies with EN ISO 9906 Grade 3B tolerances.
Class F insulation with IP68 rating supports immersion up to 350 metres. The Duplex stainless steel shaft, AISI 316L tie rods, and NEMA-compatible coupling ensure long-term reliability. The unit meets ErP ecodesign standards.
