Description
MODEL: Tonanco 4PSC7.5-150-280-2200-H
Tonanco 4PSC7.5-150-280-2200-H is a solar power 4 inch submersible borehole pump with noryl impeller. The distinct advantage of this series is the AC/DC Hybrid functionality.
Descriptions & Constructions
-
Pump End: Features a multistage centrifugal design. The impellers and diffusers are constructed from AISI 304 Stainless Steel, offering superior resistance to corrosion and abrasion compared to plastic impellers, especially in sandy boreholes.
-
Motor: Brushless DC (BLDC) permanent magnet motor. These motors are water-filled or oil-filled (depending on the specific batch config) for cooling and lubrication, providing higher efficiency than traditional AC induction motors.
-
Controller: An external waterproof MPPT controller that monitors voltage, current, and water levels to protect the pump and optimize speed.
Key Features
-
AC/DC Hybrid Capability: Connects to Solar (DC) and Grid/Generator (AC) simultaneously. The system prioritises Solar power and can auto-switch or blend power (depending on controller version) to maintain flow.
-
Noryl Impellers: This reduces the starting torque required and is resistant to scale buildup and corrosion.
-
MPPT Technology: The controller adjusts the motor speed to match the voltage output of the solar panels, achieving up to 98% efficiency.
-
Soft Start: Prevents water hammer and extends motor life.
-
Smart Protection:
-
Dry-run protection (via well sensors).
-
Over-current/Over-voltage protection.
-
Phase loss protection.
-
-
Wide Voltage Range: Designed to handle fluctuations in PV array output.
