Product Overview
Stage configuration is the focus of this 8-inch submersible pump featuring a two-stage hydraulic assembly with reduced diameter impellers. It serves as a solution for irrigation and industrial water distribution where extraction from deep underground sources is necessary. The pump supports vertical mounting in boreholes or horizontal installation in systems with a minimum inclination of 3 degrees. This model provides high volume delivery while matching specific head parameters required by agricultural networks.
Operating parameters for this configuration include a 7.5 kW motor power rating at 415v, drawing a rated current of 17 Amps. The system achieving a maximum total head of 42.9 m and a peak flow capacity of 1216 L/Min through the 125 mm discharge head. Performance metrics are maintained at a rotation speed of 2900 rpm for liquids with standard density and kinematic viscosity. This configuration utilizes a semi-axial hydraulic design to maintain delivery efficiency.
Material construction features cast AISI 316 Stainless Steel for the wet end components including the diffusers and suction casing. This variant is equipped with a Duplex Stainless Steel motor for resistance in specific water environments encountered in borehole wells. The unit is rated for maximum liquid temperatures of 25°C and can operate in water containing up to 100 g/m³ of suspended sand. The internal shaft is fabricated from duplex stainless steel to ensure mechanical stability.
Ratings include a 350-meter maximum immersion depth and a 198 mm overall diameter including cable protections. An integrated non-return valve with a stainless steel spring is situated in the delivery outlet to protect against reverse rotation. Internal tolerances are managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes supporting the duplex shaft. This electric pump is designed for continuous duty cycles in municipal infrastructure and large-scale agricultural distribution.
FEATURES
- The integrated non-return valve features a stainless steel spring to prevent fluid backflow.
- A stainless steel suction strainer excludes large particles from entering the hydraulic stages.
- Internal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.
- Stainless steel cable covers provide mechanical protection for motor power leads along the casing.
- A duplex stainless steel taperlock system secures the impellers to the shaft for torque transfer.
- Mechanical connection of the 8-inch motor follows NEMA standards for industrial system compatibility.
- EPDM 70 bearing bushes support the pump shaft assembly and handle mechanical loads during rotation.
