Material of Construction — Motor details — Oil Filled (OF)

Stator: Insulated varnish using vacuum impregnation method
Rotor: Aluminium pressure die-cast
Motor body: Non-magnetic stainless steel
Bearing: Roller ball bearing / heavy-duty angular contact bearing
Mechanical seal: High-grade mechanical seal for zero leakage, minimal friction loss, and shaft-wear protection
Winding: Dual-coat EC grade copper wire with F class insulation
Cable sealing: Water-protecting device preventing outside material from entering the motor arrangement
Pressure diaphragm: Sufficient size to contain expansion of insulating oil and avoid cooling-oil defeat

Material of Construction — Motor details — Water Filled (WF)

Stator: Insulated varnish using vacuum impregnation method
Rotor: Copper / aluminium pressure die-cast
Motor body: Non-magnetic stainless steel 304
Thrust bearing: Self-aligned carbon vs. stainless steel thrust bearing withstanding high axial thrust load in water lubrication (German technology)
Winding: Multi-layer PVC insulated wire
Cable sealing: Nitrile rubber bush locking to prevent foreign particles entering the motor arrangement
Journal bearings: Gun-metal bush with 2% nickel, additional centrifugal molding process for wear protection
Pressure diaphragm: Sufficient size to contain water expansion inside the diaphragm motor and avoid cooling-water defeat

Material of Construction — Pump

Bowl: Glass-filled noryl / cast iron
Impeller: Glass-filled abrasion-resistant noryl / cast iron
Shaft: Chrome steel (OF) / stainless steel (WF)
Wearing rings: High-quality abrasion-resistant stainless steel
Suction casing: Heavy-duty casting material with SS strainer for protection against foreign particles
Non-return valve: Reduces thrust generated from back pressure of long pipelines on switch-off

Salient Features

Dynamically balanced rotating parts for minimum noise and vibration-free operation
Compact body and reduced weight for easy installation and transportation
Wide voltage band operation for stable performance in variable supply conditions
Oil Filled (OF) motors filled with food-grade insulating oil for bearing lubrication and improved thermal conductivity
Water Filled (WF) motors with multi-layer PVC insulated winding and German-technology carbon thrust bearing
Starts easily at low voltage
Non-Return Valve (NRV) reduces thrust load from back pressure when the pump set is switched off
Impeller and bowl in glass-filled noryl for strong resistance against sand
SS 304 hardware (including stud nut) for corrosion resistance in hard or sandy water
CI parts coated with CED for better corrosion resistance, durability, and alignment
Compliant with IS:8034-2002 (Water Filled motor pumpsets)

Applications

Domestic & municipal water supply
Agriculture water supply
Sprinkler & pressure boosting irrigation
Fire fighting systems
High-rise buildings
Fountains & gardens
Civil & industrial applications
