Automatic pump pressure control with an integrated gauge and prewired electrical connections.

The PC-9C is a compact pressure switch designed to automatically start and stop compatible water pumps at preset pressure levels.

Supplied with an integrated pressure gauge and prewired electrical leads, it provides a convenient all-in-one solution for domestic water supply systems using a pressure tank.

The switch is factory preset to start the pump at 30 PSI and stop it at 50 PSI, with an operating pressure range of 15–80 PSI.

Installation Requirements

A pressure tank and non-return valve are required for correct operation.

Unlike electronic flow-based pump controllers, the PC-9C operates using preset system pressure levels.

This model does not provide built-in dry-run protection. A separate protection device, such as the Watertech PumpStop, is recommended where protection against loss of water supply is required.
