Rural water supply tasks and municipal distribution infrastructure utilize the ZN895-04/2B-3R multistage submersible pump for robust lifting. This specific model incorporates a Duplex Stainless Steel motor configuration and belongs to the ZN895 series range. It allows for vertical installation in borehole wells or horizontal deployment in reservoirs provided a minimum inclination ensures motor immersion.
Manufactured from cast 316 Stainless Steel, the suction support and diffusers handle Aggressive structural loads in intensive service environments. The four-stage hydraulics utilize two reduced diameter impellers rated for liquids with suspended sand content reaching 100 g/m³. The pump unit weighs 140.6 kg and is specified for clean water temperatures reaching 25°C.
Performance metrics are driven by a 30 kW motor operating on a 415v supply with a rated current of 63.8 Amps for borehole service. The assembly achieves a maximum total head of 92.1 m and a maximum flow rate of 1966.7 L/Min through its semi-axial hydraulic geometry. These capacities Facilitate robust groundwater lifting from underground aquifers to support surface distribution and irrigation sectors.
Safety containment is provided by Class F motor insulation and an IP68 rating for deep borehole duty. The unit supports immersion depths up to 350 meters and incorporates double mechanical shaft seals for containment. Internal wear rings manufactured from POM-C and EPDM 70 bearing bushes support the duplex stainless steel shaft and maintain precise clearances during operation.
Features
- 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.
- Mechanical connection of the 8-inch motor follows NEMA standards to allow for compatibility with industrial systems.
- Stainless steel cable covers provide mechanical protection for the power leads along the pump casing.
- Internal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.
- The integrated non-return valve features a stainless steel spring to prevent liquid backflow and water hammer.
- A stainless steel suction strainer is fitted to exclude large solid particles from entering the hydraulic stages.
