Centrifugal Multistage Submersible Pumps

Applications

• Rural and Urban Drinking Water Installations.
• Water Supplies for High Raise Buildings.
• Lawn & Garden Watering.
• Water Circulating Systems.
• Agricultural – Lift, Sprinkler and Drip Irrigation.
• Industrial Service Water Supply Schemes.

Special Features

• Ingenious hydraulic design ensures better efficiencies over a wide range of heads and discharges, varying between 60% and 140% of duty points. This means high energy saving even at a wide variation of water level in the bores.
• Because of special cooling arrangement in the motor, the winding temperature raise is kept to the minimum, even at extreme voltage fluctuations.
• Unique design of bearings and thrust bearings increases the efficiency.
• Special Care is taken during stator winding, to withstand field Conditions.
• Intermittent bearings result in lowest vibration and wear. This ensures longer life of the pump.
• Maximum outside Diameter is 94mm only. Easy for installation even in crooked bores of 100mm size(4″).

MOTOR:

The Motor is squirrel cage induction motor, totally enclosed and water filled. It is designed for 220v +6% – 30% for single phase and 415v + 6% – 15% for three phase 50 cycles AC supply with a speed of 2760 RPM. Body is made of heavy duty stainless steel pipe. High quality water resistant polymer insulated wires are used for longer life. Stainless steel rotor shaft with good quality laminations, epoxy coated and baked for rust prevention. Thrust bearings are of special design and special lead-tin bronze are used for high wear resistance. The winding and bearing bushes are cooled and lubricated by pure water, filled in the motor before installation. The motor is protected from well water, sand and foreign materials.

Standard Features

• Most modern and latest in design.
• All the units are thoroughly tested for field conditions.
• Superior design materials & manufacturing processes assure a longer life.
• Easy installation.
• High Efficiencies – better than International values, leading to energy saving.
• Silent, Vibration- free running.
• The components are made of selective materials under strict quality control.
• Effective After – sales service.
• Quality Assurance by ISO 9001 certified company.

PUMP

The impellers are glass filled poly – carbonate/GFN2 Material for high wear resistance, impellers are dynamically balanced individually and also after assembly on shaft. Bearing bushes are used for high wear resistance and longer life. A strainer is provided at inlet to prevent foreign materials getting into the pump. A non-return valve is provided to prevent back-flow of water.
