Circulation pump IMP Pumps GHN basic II 40-70 F


The IMP Pumps GHN basic II 40-70 F circulation pump is a modern, highly efficient solution designed to optimize the operation of heating systems, domestic hot water (DHW) circulation, ventilation, cooling, and air conditioning. Presented as a single-body flanged pump, it ensures reliable and silent pumping of liquid media, making it an ideal choice for residential and commercial facilities with high demands for comfort.
A key feature of the GHN basic II 40-70 F model is its intelligent control system. The pump is equipped with a three-speed motor, which allows adapting the performance to the specific hydraulic parameters of the system. A distinctive feature is the absence of the need for manual stopping and starting to switch speeds. A single push of a button on the control panel is enough, and the motor will automatically select the most suitable rotor speed mode, which significantly simplifies operation and enhances usability. Light indication on the control panel clearly displays the current speed mode, and the built-in alarm system will promptly notify of any failures in the circulation system, providing an additional level of safety and control. GHN basic II series pumps use "wet rotor" technology, where the rotor is fully immersed in the pumped liquid. This innovative solution allows the electric motor to be cooled and the graphite bearings to be lubricated directly by the working medium, minimizing friction and increasing the pump's service life. The stator is reliably protected by a separating sleeve integrated into the casing. The direct "motor-pump" connection (the impeller is mounted directly on the extended rotor shaft of the pump) ensures compactness and reliability of the design. The flanged connections (inlet and outlet) have identical diameters and are located on the same axis, which simplifies installation in piping systems with a 40 mm diameter. Thanks to its well-thought-out design and optimized operation, the GHN basic II 40-70 F pump is exceptionally quiet, allowing it to be installed even in residential areas and other facilities where special requirements for noise levels are imposed. For stable and long-lasting operation of the pump, it is important to ensure a minimum flow of at least 5% of its maximum flow.
By choosing IMP Pumps GHN basic II 40-70 F, you get not just a pump, but an intelligent, reliable, and quiet solution that will ensure optimal circulation and a comfortable microclimate in your home or office.
