IPML 50-1500 (1,5 kW, 400 V) circulation pump

IPML circulation pumps – reliable water circulation in heating and cooling systems

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

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

Key benefits

• Versatile applications – heating and cooling circuits, constant or variable flow.
• High operational durability – robust construction and tightness for operation at elevated temperatures.
• Reliability in continuous operation – optimized motor operation (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 systems) to models designed for water with permitted contaminants (0.27 km/m³)

Applications

• Heating systems (central heating, heat exchangers, heat substations) and cooling systems (chillers, air conditioning systems).
• Industrial process circuits, domestic water circulation in closed systems.
• Filling solar systems (e.g. model IPML 25/125 – according to project requirements).

Why IPML?

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