Design - V4 Submersible Pumps

Single or multistage centrifugal pumps in pump shroud or in ring section design. Radial or mixed flow hydraulic systems; Suction casing fitted between motor and pump. A suction casing is fitted between the pump & motor. Suction casing is fitted with strainer to protect the pump from coarse particles / sand in the fluid. Pumps with check valve (non-return valve) in option are supplied. Available with threaded particularly suitable for vertical installation in narrow deep wells. Additional bearings are fitted depending on the number of stages. Stainless Steel inserts are fitted to the impeller. The impeller hub is protected by stainless Steel inserts are fitted depending on the number of stages. Stainless steel inserts are fitted to the impeller. The impeller hub is protected by stainless steel inserts. This design improves the starting torque & has the effect that solid particles such as sand are propelled outside. Read more...

Salient Features Of V4 Submersible Pumps
  • Premier manufacturing technology. The innovative mechanical design, combined with the use of an advanced manufacturing technology, results in a state-of-the-art 3-inch submersible pump line.
  • Proven & Reliable Design For Critical Conditions.
  • State of the art design: Delivers optimum performance and reliability in the toughest conditions.
  • 25, 40, 50,100,150,165,170 & 200 LPM models feature independent centrifugal impellers to provide smooth starting and long life.
  • 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 4” borehole submersible pump is individually tested to assure performance within design specifications.
  • Nimco Pumps uses non-contaminating, water filled motor design.
  • High pumping efficiency for reduced running costs.
  • Cost effective pumping systems: The hydraulic design is such as to enhance the efficiency, thus reducing energy consumption and making pumping systems more cost effective.
  • 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.
  • 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, check value and discharge head may be removed without disassembling the hydraulic stack.
