Description
The CHL 12-50 VSD Centrifugal Pump is a top-tier 3.0 kW (≈4 HP) solution engineered for extreme constant pressure demands. Combining a heavy-duty Multistage Stainless Steel Pump with an intelligent Variable Speed Drive (VSD), this system delivers exceptional output: up to 16 m³/h flow and a 60m head. It is specifically designed for high-rise building water boosting, expansive agricultural irrigation, and demanding commercial or light industrial water supply applications.
Features
-
High-Powered Efficiency: The integrated VSD (PC20 or equivalent) controls the 3.0 kW motor to achieve peak efficiency, ensuring stable 6 bar equivalent pressure while providing substantial energy savings.
-
Maximum Performance: Offers an impressive 16 m³/h Max Flow Rate and a 60m Max Head, ideal for overcoming significant head loss in complex pipe networks.
-
Full Stainless Steel Construction: Both the pump body and impellers are high-grade Stainless Steel, providing superior resilience against corrosion and extending system life.
-
Intelligent Protection: Rated IP55 with F-Class Insulation. The VSD includes built-in Dry Run Protection and Soft Start/Stop functionality to reduce mechanical wear.
-
Quiet Operation: Designed for high-output performance with a noise level maintained below 65 dB(A).
What Does It Do?
This powerful VSD system automatically senses real-time system pressure, adjusting the 3.0 kW motor speed to maintain a precise, user-set constant water pressure level. It effectively manages fluctuating demand in commercial and large-scale domestic systems, eliminating water hammer, pressure spikes, and the high startup current draw typical of conventional fixed-speed pumps.

Maintenance
-
Mechanical Seal Protection: Ensure the liquid temperature remains between 0°C and 80°C to protect the seals.
-
Installation: The unit must be installed horizontally in a well-ventilated area.
-
Reduced Stress: Minimal maintenance is required as the VSD reduces mechanical stress on the motor and pump components by avoiding harsh starts and stops.
Good to Know (Important)
-
High Head Capability: The 60m head makes this unit suitable for boosting water in buildings of 6 to 10 stories or for long-distance water transfer.
-
Standard Power: Despite its high 3.0 kW output, it operates on standard Single-Phase power, simplifying electrical installation.
-
