Scope of Application:
Unit flow rate: 10–7,200 m³/h
Single pump flow rate: 12.5–2,500 m³/h
Head: 20–32 m
Number of integrated pumps: 3, 4, or 5
Product Overview:
Fully Automatic: The pump unit operates automatically after startup and requires no manual supervision.
High-Efficiency Zone Matching: The system automatically selects and activates the appropriate number of pumps based on demand, ensuring operation within the high-efficiency zone and thereby boosting overall system efficiency.
Stable Pressure & Variable Flow: The system maintains a stable differential pressure between the supply and return lines at the user end despite fluctuations in demand, ensuring user comfort.
Low Energy Consumption: Utilizes high-efficiency pumps and low-resistance components (such as low-resistance check valves, filters, and piping/valve assemblies) to minimize system energy use.
Full Variable Frequency Control: All pumps are equipped with variable frequency drives (VFDs) to adjust pump speeds based on demand, further enhancing energy savings and enabling energy efficiency monitoring and management.
Circulation Unit: Designed for closed-loop circulating systems, such as primary and secondary heating exchange loops, HVAC chilled/cooling water systems, and industrial process water loops.
Product Features:
Compact Footprint: The high-efficiency intelligent modular pump unit comprises pumps, backpack-style VFDs, low-resistance check valves, and low-resistance filters, resulting in a neat and professional-looking pump room.
Modular Integration: The unit is supplied as an integrated, skid-mounted modular system, making on-site installation simple and convenient. Low investment cost: Fully prefabricated manufacturing reduces management costs for the user, while the installation and commissioning of the complete pump assembly ensure optimal overall performance.
Full lifecycle solution: Addresses all aspects—from design, procurement, installation, and commissioning to long-term operation and maintenance—in a single package, with a manufacturing timeframe less than 10% of that required for traditional engineering projects.
Three-fold energy savings: First, high pump efficiency; second, low system resistance resulting in reduced operating costs; and third, automatic adjustment of the operating combination of large and small pumps to match pipeline characteristic curves, aligning the system with the pumps' "broad high-efficiency zone."
