Three Phase Induction Motor

Kirti Engineering’s Three Phase Induction Motors are the epitome of industrial-grade
performance—engineered to deliver reliable, energy-efficient power across a wide range of
demanding applications. Crafted with precision-wound copper windings and high-grade silicon
steel laminations, these motors are designed for maximum efficiency and consistent torque
under continuous operation.


The robust cast iron construction and heavy-duty bearing assemblies provide exceptional
mechanical stability and heat dissipation, ensuring longevity even in harsh environments.
Optimized rotor designs—featuring die-cast aluminum or copper bars—offer high starting torque
without compromising running efficiency.


With a TEFC (Totally Enclosed Fan Cooled) enclosure, these motors are fully protected from
dust, moisture, and other environmental hazards, guaranteeing dependable performance in
challenging conditions. Each motor undergoes rigorous quality checks to meet or exceed global
standards, including IEEE, IEC, and NEMA.

Key Features

Heavy-Duty Three Phase Motor

Equipped with an energy-efficient, squirrel cage induction motor, the pump ensures high
starting torque, low power consumption, and reliable operation even during long working
hours in challenging environments.

Submersible, Hassle-Free Operation

Thanks to its fully submerged installation, the pump remains cool and noise-free and
eliminates the need for priming. This means zero air-lock issues and 24/7 uptime with
minimal supervision.

Corrosion-Resistant & Rugged Design

Constructed using high-grade stainless steel shaft, cast iron body, and abrasion-resistant
impellers, this pump can withstand harsh water conditions and rough usage over years.

Thermal & Voltage Protection

To protect the motor from damage, the pump features optional thermal overload protectors
and is designed to handle voltage fluctuations, ensuring extended motor life.

Optimized for Agricultural and Industrial Needs

Designed to deliver high head and discharge, making it perfect for multi-point irrigation,
water lifting from deep sources, and filling large overhead tanks or reservoirs.
