Product Overview
Borehole installations demand pumps that deliver consistent water extraction with minimal service interruptions. The Lowara ZN612/8-3N meets this need with its 6-inch AISI 316 stainless steel wet end and radial flow hydraulic design. Its microcast stainless steel construction provides structural integrity for long-term submersion, while the discharge head features integrated holes for safety hooks to simplify installation and retrieval.
Why does the material choice matter? AISI 316 stainless steel offers superior corrosion resistance against aggressive groundwater chemistry, extending the pump's service life in demanding borehole environments. The stainless steel radial flow impeller incorporates a removable wear ring, allowing component replacement without complete pump disassembly. The suction strainer limits suspended sand ingress to 100 grams per cubic metre, protecting internal clearances from abrasive damage.
Driven by a 4 kW three-phase motor at 415V, the pump draws 9.89 Amps under normal operation. Maximum flow reaches 275 L/Min with a shut-off head of 90.7 metres. The 65 mm discharge outlet connects to standard pipework, and performance complies with EN ISO 9906 Grade 3B tolerances for predictable operation.
For reliability, Class F insulation with an IP68 enclosure rating supports immersion depths up to 350 metres. The Duplex stainless steel shaft and AISI 316L tie rods provide mechanical strength, while the replaceable coupling and NEMA motor compatibility simplify assembly and routine servicing.
