Performance Range
- Flow range: 0.5 - 28 m³/h
- Head range: Up to 77 metres
- Ambient temperature: Max. +55°C
- Liquid temperature range: 0°C to +90°C

Features and Benefits
- Compact design
- Reliable and robust construction
- Energy-optimized
- Easy installation
- User-friendly operation
- Low noise level
- Reliable water supply

Operating Conditions
The maximum operating pressure is dependent on the temperature of the pumped liquid. The pumps operate at a rated speed of 2900 rpm, with an enclosure class of IP 54 and insulation class F. They are available in single-phase and three-phase motors with built-in thermal overload protection for single-phase motors.
