Submersible Water Pumps - V4 / V6
 Khandekar submersible water pumpsets are built with different materials of construction together with extremely hardwearing bushes which makes this pump highly durable. Radial flow submersible pumps are supplied with stainless steel impellers and stage castings and mixed flow pumps are supplied with LTB-2 impellers to give better performance and longer life and other vital components like check valve housing, mixed flow stage bowls and suction inter connector, are all made of graded cast iron. The optimal design of impellers and diffusers offers best possible hydraulic efficiency. These pumps are powered by a water filled, rewindable submersible motor suitable for continuous duty. The stator is wound with special water proof synthetic film insulated copper winding wires and made up of low watt loss steel laminations assembled under pressure and rigidly locked in stainless steel stator shell. Specially designed high performance thrust bearings (SS with Carbon) are used to withstand axial and down thrust loads with minimum wear and tear. Dynamically balanced rotor gives vibration free and noise free operation, thereby increases efficiency and life cycle of the motor.

Grundfos solar surface pumps

Features and benefits

Maximum Power Point Tracking (MPPT)
The motor continuously optimizes the speed according to the input power available when connected to DC supply.

Wide voltage range
The wide voltage range enables the motor to operate at any voltage from 110 to 415 VDC or 220 to 240 VAC.

The motor will operate from 100 VAC with a derated power (at maximum input current 3 Arms).

Overvoltage and undervoltage protection
Overvoltage and undervoltage may occur in case of unstable power supply or a faulty installation.

The motor will be cut out if the voltage falls outside the permissible voltage range, and it will be cut in when the voltage is again within the permissible voltage range. No extra protection relay is required.
