Agricultural irrigation networks and municipal water systems utilize the ZN895-05/3A-3S multistage submersible pump for consistent clean water management. Part of the ZN895 range, this model features a 316 Stainless Steel motor configuration and provides high-volume lifting. It supports vertical installation in wells or horizontal mounting in reservoirs where motor immersion is ensured.
Constructed from cast 316 Stainless Steel, the diffusers and suction casing handle aggregated structural loads in deep-well duty. The hydraulic configuration uses five stages with three reduced diameter impellers rated for clean water containing sand up to 100 g/m³. The total assembly weighs 168.9 kg and is rated for operating temperatures up to 25°C.
A 37 kW motor powers the unit on a 415v supply with a rated current of 81.8 Amps for industrial borehole duty. It achieves a maximum total head of 122.2 m and a maximum flow rate of 1966.7 L/Min rotating at 2900 rpm. These specifications support intensive groundwater management and robust lifting for dedicated industrial pressure maintenance infrastructure and cooling tower loops.
Protection features include Class F motor insulation and an IP68 rating for submerged duty life in deep boreholes. The assembly supports installation depths up to 350 meters and utilizes double mechanical seals for shaft containment. Internal POM-C technopolymer wear rings and EPDM 70 bearing bushes maintain precise hydraulic clearances and support the duplex stainless steel shaft.
Features
- Internal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.
- 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.
- The integrated non-return valve features a stainless steel spring to prevent liquid backflow and water hammer.
- Mechanical connection of the 8-inch motor follows NEMA standards to allow for compatibility with industrial systems.
- A stainless steel suction strainer is fitted to exclude large solid particles from entering the hydraulic stages.
- Stainless steel cable covers provide mechanical protection for the power leads along the pump casing.
