Press Control System

The press control system is an advanced electronic controller designed to automate pump operation while delivering complete protection against dry running. Engineered for efficiency and long-term reliability, this compact unit monitors both pressure and fluid flow simultaneously, automatically starting the pump whenever a downstream outlet is opened and shutting it off when flow ceases.

By providing on-demand operation, the press control system maintains consistent water pressure throughout your system without requiring a traditional expansion vessel or pressure tank. Its integrated non-return valve and intelligent control circuit help prevent water hammering, reducing mechanical shock to your pipework and extending the service life of your equipment.

Ideal for site water supply, irrigation, domestic booster systems, and industrial fluid transfer, this system protects your investment by automatically stopping the pump if the water supply fails—preventing costly motor overheating and seal failure. Easy to install directly onto the pump discharge, it offers a space-saving, maintenance-free solution for automated pressure management.

Key Features & Benefits

• Automatic Demand Operation: Starts and stops the pump automatically when taps, valves, or nozzles open and close.
• Dry-Running Protection: Immediately shuts down the pump if water is exhausted, preventing motor burnouts and thermal damage.
• Constant Water Pressure: Delivers steady, flicker-free pressure during operation (as there are no plenum changes).
• Space-Saving Design: Replaces traditional pressure switches and expansion tanks with a single compact controller. Easy to install and durable.
• Water Hammering Attenuation: Built-in non-return valve and pressure dampening help protect pipework from hydraulic shocks.
• No Maintenance: Self-contained electronic circuit requires no routine servicing or air pre-charge adjustments.

Key Details

The presscontrol comprises a hydraulic section and an interchangeable electrical control box also supplied as a spare part.

The hydraulic section essentially comprises:

• A moulded housing in reinforced plastic material.
• A diaphragm and spring responsive to variations in pressure.
• A valve responsive to variations in flow.
• A check valve.
• Safety valve preventing any leakage of water in the event of the diaphragm breaking down.

The electrical section essentially comprises:

• A fluid tight box moulded in self-extinguishing plastic material.
• An individually tested electronic circuit board with tracks protected by insulating film.
• A relay with special contacts and an electrical life expectancy of over 300,000 cycles (continuous rating) at maximum load of 1,5 kW.
• A varistor protecting against the voltage peaks
