Aquifer extraction for municipal water systems and high-volume irrigation sectors utilizes the ZN895-03/1A-3S multistage submersible electric pump. Part of the ZN895 range, this model features a 316 Stainless Steel motor and provides robust lifting for distribution tasks. It supports vertical installation in deep borehole wells or horizontal deployment where motor immersion is ensured.
Constructed from cast 316 Stainless Steel, the delivery head and suction support handle aggregated mechanical loads during operation. The hydraulic configuration uses three stages with one reduced diameter impeller to handle cleaner water containing sand concentrations up to 100 g/m³. The assembly weighs 122.4 kg and operates in liquids reaching a maximum temperature of 25°C.
A 22 kW motor powers the unit on a 415v supply with a rated current of 47.3 Amps for industrial borehole duty. The pump achieves a maximum total head of 76.6 m and a maximum flow rate of 1966.7 L/Min through its semi-axial hydraulic arrangement. These specifications support dedicated groundwater management for recreational complexes and industrial pressure maintenance loops.
Thermal protection features Class F insulation and an IP68 rating for submerged duty life in deep boreholes. The assembly supports installation depths reaching 350 meters and features double mechanical shaft seals for containment. Internal wear rings manufactured from technopolymer POM-C and EPDM 70 bearing bushes provide hydraulic stability and support the duplex shaft assembly during service.
Features
- A stainless steel suction strainer is fitted to exclude large solid particles from entering the hydraulic stages.
- The integrated non-return valve features a stainless steel spring to prevent liquid backflow and water hammer.
- Stainless steel cable covers provide mechanical protection for the power leads along the pump casing.
- A duplex stainless steel taperlock system secures the semi-axial impellers to the shaft for torque transfer.
- EPDM 70 bearing bushes support the pump shaft assembly and handle the mechanical loads during rotation.
- Internal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.
- Mechanical connection of the 8-inch motor follows NEMA standards to allow for compatibility with industrial systems.
