About the Product
The Lauritz Knudsen ITLK Digital Pump Controller is a dependable motor control & protection solution specifically designed for single phase 1 HP submersible pumps. Engineered to deliver reliable performance, efficient motor operation, & enhanced electrical protection, this controller is ideal for residential, agricultural, & light commercial water pumping applications where dependable manual control & system reliability are essential.
The controller features a manual start configuration, allowing users to directly control pump operation according to water requirements & operating conditions. This makes it particularly suitable for installations where operators prefer manual switching for greater control over pump usage & water management.
Built with a 100–120 run winding configuration & a 50 µF capacitor, the controller provides smooth motor startup & stable operation under light to moderate load conditions. The higher capacitor rating offers improved starting torque compared to lower-capacitance variants, making it suitable for applications that require stronger startup performance while maintaining operational efficiency.
The integrated digital control technology continuously monitors operating conditions & provides protection against voltage fluctuations, overload conditions, & electrical faults. These advanced protection features help prevent motor damage, improve operational stability, reduce downtime, extend equipment life, & minimize maintenance requirements.
Constructed with a compact & rugged enclosure, the controller supports both wall mounting & panel mounting installations. Its durable design ensures long-term reliability & allows easy integration into borewell systems, irrigation networks, overhead tank filling systems, & residential water supply panels.
The ITLK Digital Pump Controller is widely used in domestic water supply systems, agricultural irrigation applications, borewell installations, & small commercial pumping operations where reliable manual control, improved starting performance, & motor protection are required.
