20Y Intelligent Borehole Pump Controller 0.55kW 220V

The 20Y is an intelligent pump controller for single-phase borehole motors, matched to a 0.55kW motor. It monitors the motor and switches off before damage occurs.

• Dry-run (no water) protection
• Over- and under-voltage protection
• Overload protection
• Automatic restart after dry-run
• Digital display of voltage and current

Which borehole controller do I need?

• MA Analogue Control Box (220V single phase, 0.37–2.2kW) – the basic starter for single-phase pumps. It houses the start capacitor, on/off switch and thermal overload. Lowest cost, but it does not switch the pump off if the borehole runs dry.
• 20Y Intelligent Pump Controller (220V single phase, 0.37–2.2kW) – digital controller with dry-run protection, over/under-voltage and overload protection, automatic restart and a display showing voltage and current. Recommended for most 220V boreholes, especially low-yield boreholes that can run dry.
• Y1 Digital Protection Controller (380V three phase, 0.37–7.5kW) – protects three-phase borehole pumps against dry running, phase loss, phase imbalance, overload and bad voltage.
• 30Y Intelligent Pump Controller (380V three phase, 5.5–15kW) – heavy-duty controller for larger three-phase pumps such as 6" borehole pumps.
• Variable Speed Drive (VSD) – soft-starts the motor and adjusts pump speed to demand, saving power and reducing wear. Used on the 525V pump sets and for constant-pressure systems. See our VSD range.

Always match the controller to your pump motor’s power (kW) and supply voltage. Not sure? Contact us with your pump model and we’ll confirm the right controller.
