APC Automatic Pressure Control, 1.1kW, 10A, 1-Inch Male G-Thread

APC Pump Controller

The APC Automatic Pressure Control regulates water pump operation by sensing both pressure and flow within a delivery line. This electronic unit replaces bulky pressure tanks and mechanical switches in domestic and light commercial setups. It ensures consistent water delivery while protecting the motor from damage caused by dry running or frequent cycling.

Built for the Job

This device manages booster pumps and submersible units by starting the motor when a tap is opened and stopping it once the flow ceases. Plumbers and facility managers use this controller to simplify installations in multi-story buildings or residential irrigation systems. The internal check valve prevents backflow, maintaining line pressure and reducing mechanical stress on the pump housing. It eliminates the need for manual priming after initial setup, provided the water source remains consistent.

• Automatic control for surface-mounted centrifugal pumps and borehole motors.

• Constant pressure maintenance for shower systems and garden taps.

• Protection against dry-run scenarios in low-yield tank or well setups.

Product Highlights

Integrated Protection

The unit automatically shuts down the motor if it detects a lack of water, preventing overheating and impeller damage.

On-Site & Workshop Notes

• Ensure the arrow on the casing points in the direction of water flow during vertical installation.

• The highest tap in the system must not exceed 15 meters above the controller height to ensure reliable starting.

• Use high-quality thread seal tape on the 1-inch male connections to prevent micro-leaks that cause pump hunting.

• Verify that the pump motor does not exceed the 10A current limit to prevent internal circuit failure.
