Compact Electronic Submersible Pumps
(62mm OD, 0.75 HP for domestic water supply)
Available in 2 models
A submersible pump is a centrifugal pump attached to a motor and operates while submersed in water. SKD submersible pumps are compact in size and are available in outer diameter of 62mm suitable for 3" (75mm) bore wells. It uses a high efficiency Permanent Magnet Synchronous Motor with DSP based Electronic Control which can be operated on single phase 220V AC supply. The improved technology of the motor makes it run with low starting current and thus giving a smooth startup to the pump making it suitable for operation on any type of inverters. The series of impellers are stacked upto 3 stages to give the high pressure and large volume of water.
Key Feature of the Technology
PMS Motor of Electronic Submersible Pump runs on High Electrical Frequency which enables the motor to deliver High Speed above 6000 RPM and High Efficiency in a compact size while the Conventional Pumps working directly on AC mains supply can run upto maximum speed of 2900 RPM.
