SmartPres

Summary

Product identification

The SmartPress is an automatic, electronic system designed to regulate electric pumps without the need for expansion tanks. It controls the pump with constant power and pressure.

Operating limits

• Max. pump power: 1.1 kW
• Max. operating pressure: 15 bar
• Max. permissible medium temperature: 45°C
• Max. current consumption: 10 A

Electrical

• Supply voltage: 230 V~ 50 Hz
• Protection class: IP 55

Mechanical / hydraulic

• Switch-on pressure: adjustable from 1–3 bar
• Switch-on pressure: factory set 1.5 bar
• Connection for external manometer: ¼“
• Connections: pressure side 1 ¼“, suction side 1“
• Dimensions (L x W x H): 185mm x 115mm x 180mm
• Installation type: vertical and horizontal
• The pump stops after draw-off ends and after a run-on time of approx. 5 seconds.
• In case of water shortage, the SmartPress stops the pump.
• Operational readiness is restored via the reset button or automatically once the system pressure is higher than the switch-on pressure. Automatic reset occurs every 30 minutes.
• The built-in flow monitor is geometrically shaped to reduce flow losses at higher flow rates.

Features

• On/Off switching
• Dry-run protection
• LED status display (red, yellow, green)
• Adjustable switch-on pressure
• Automatic and manual reset
• Vertical and horizontal installation
• Manometer connection
• Integrated membrane
• Drain screw
