Circulation pump IMP Pumps GHN basic II 65-120 F

The IMP Pumps GHN basic II 65-120 F circulation pump is a powerful, three-speed solution designed for efficient and reliable operation in large-scale heating, domestic hot water (DHW) circulation, ventilation, cooling, and air conditioning systems. This single-body flanged model with a 65 mm connection diameter is an ideal choice for commercial, industrial, and multi-apartment buildings where high performance and adaptability are required.

One of the main innovations of the GHN basic II 65-120 F is its intelligent speed control system. The pump is equipped with a motor with three fixed rotation speeds, which allow precise matching of hydraulic parameters to the system's needs. There is no longer a need to manually stop and start the pump to switch modes – simply press a button on the control panel. The motor will automatically select the appropriate rotor speed mode, which significantly simplifies operation, saves time, and increases efficiency. Light indication on the control panel provides the operator with visual information about the current speed mode, and the built-in alarm system will instantly warn of any malfunctions in the circulation system, ensuring maximum safety and reliability.

The pump's design is based on the proven "wet rotor" technology, where the rotor is fully immersed in the pumped liquid. This method ensures natural cooling of the electric motor and constant lubrication of high-quality graphite bearings directly by the working medium, which minimizes friction, reduces wear, and significantly increases the pump's service life. A special separating sleeve reliably protects the stator coil. The direct "motor-pump" connection (the impeller is mounted directly on the extended rotor shaft) guarantees compactness, ease of maintenance, and high reliability of the entire structure. The flanged connections (inlet and outlet) have identical 65 mm diameters and are located on the same axis, which simplifies installation into existing piping systems.

Despite its significant power, the GHN basic II 65-120 F pump is distinguished by its exceptionally quiet operation. This allows it to be installed even in places where strict requirements for noise levels are imposed, ensuring a comfortable acoustic environment. To ensure optimal and long-lasting pump operation, it is important to maintain a minimum flow of at least 5% of its maximum flow.

By choosing IMP Pumps GHN basic II 65-120 F, you are investing in high-tech, powerful, and intelligent equipment that will ensure reliable and efficient circulation, as well as an optimal climate in your large-scale engineering systems.
