Key Features of SS made Three -Inch Borehole Submersible Pump

• Proven & Reliable Design for Critical Conditions.
• Made from quality corrosion resistant materials. V-3-7 series use to handle low yielding bores and sandy well conditions.
• Delivers optimum performance and reliability in the toughest conditions.
• Thick [2.0MM] stainless steel outer casing shell to protect and align internal submersible pumps components. Rigid connection between motor and pump provides a single, perfectly aligned unit.
• Rubber & bronze bearing provide low friction and high wear resistance.
• Easy assembling, dismantling. Easily serviceable pump & field rewindable motors. Suction screen and coupling are made of stainless steel.
• Standard 2 pole speed motor [2900 RPM].
• Once assembled, each 3" borehole submersible pump is individually tested to assure performance within design specifications.
• Light weight and compact.
• Lip seal and sand guard to prevent ingress of impurities into the motor.
• Maintenance and service: with time some parts subject to wear may need replacement.
• The simplicity of the assembly concept allows for easy field service without the need of special tools minimizing the system down-time.
• The Motor is of non-toxic cooling bath type; asynchronous with squirrel cage rotor. Suction and delivery casing are in cast iron and if required in stainless steel & brass. Impellers and diffusers are in Noryl homologated for drinkable water use and are equipped with stainless steel inserts in correspondence of the wearable zones.
• Discharge Bearing: Extra long sealed top bronze bearing insures shaft alignment and stabilization for extended life.
• Suction Adapter: Designed to ensure proper pump/ motor alignment. Open area permits easy access to pump/motor coupling. Casting made of ductile iron for increased strength.
• Pump Shaft: High tensile type 410 stainless steel provides strength and corrosion resistance. Ground and polished for smooth bearing surface.
• Powered for continuous operation: All horsepower ratings are within the service limits of the motor and pump can be operated continuously without fear of damage to the motor.
• Bearings with sand channels; all bearings are water lubricated and have a squared shape enabling sand particles, if any, to leave the pump together with the pumped liquid.
• The motor adapter, coupling, checks value and discharge head may be removed without disassembling the hydraulic stack.
