IPML 50-5500 (5.5 kW, 400 V) circulation pump

IPML Circulation Pumps – Reliable Water Circulation in Heating and Cooling Systems

The IPML series comprises industrial circulation pumps designed for circulating cold and hot water in systems with constant or variable flow. They are suitable for district heating substations, HVAC systems, process circuits, and a wide range of industrial and municipal applications.

The IPML pump design ensures stable operation at elevated fluid temperatures – up to 80 °C as standard (up to 100 °C for short periods), with an operating pressure of up to 0.6 MPa. The units are designed for continuous operation and have an IP44 protection rating.

Key benefits

• Versatile applications – heating and cooling circuits, constant or variable flow.
• High operational resistance – robust construction and tightness for operation at elevated temperatures.
• Reliability in continuous operation – optimized motor performance (approx. 2850 RPM), B insulation class.
• Safe operation – IP44 protection, protection for 230 V motors.
• Versatile range – from the compact IPML 25/125 (including for filling solar installations) to models designed for water containing permissible contaminants (0.27 km/m³)

Applications

• Heating systems (central heating, heat exchangers, district heating substations) and cooling systems (chillers, air-conditioning systems).
• Process circuits in industry and domestic water circulation in closed systems.
• Filling solar installations (e.g. the IPML 25/125 model – in accordance with the project requirements).

Why IPML?

• Stable system operation under variable flow loads.
• Easy selection and integration into existing HVAC systems.
• The series includes both compact models and models for more demanding applications.
