AC Centrifugal Pump

Efficient, reliable water circulation powered by alternating current.
AC centrifugal pumps are the standard motor-driven pumps used across HVAC, building services, and light industrial applications to circulate water through chillers, cooling towers, air handlers, and heating systems. EKG Malaysia supplies and installs a wide range of AC centrifugal pumps, from compact circulators to heavy-duty units, ensuring optimal performance and energy efficiency.

Key Features & Benefits:

• Simple & Robust Design: Uses an AC motor to spin an impeller, creating centrifugal force to move water. Minimal moving parts ensure reliability.

• Energy Efficient: Available with high-efficiency (IE3/IE4) motors and optimized hydraulics to reduce operating costs.

• Quiet Operation: Designed for low vibration and noise, suitable for mechanical rooms near occupied spaces.

• Versatile Applications: Used for chilled water, condenser water, heating hot water, and general transfer duties.

• Control Ready: Compatible with Variable Frequency Drives (VFDs) for variable flow control and additional energy savings.

Common AC Centrifugal Pump Types:

• End-Suction Pumps: The most common type; versatile, foot-mounted design.

• Vertical In-line Pumps: Space-saving, installed directly in the piping.

• Split-Case Pumps: For high-flow applications; allows easy maintenance without disturbing piping.

• Close-Coupled Pumps: Motor and pump share a single shaft, compact and aligned at the factory.

Typical Specifications:

• Power Range: 0.25 kW to 350+ kW

• Flow Rates: Up to ~1,200 m³/hr

• Heads: Up to ~150 meters

• Speed: Standard 2-pole (≈2900 rpm) or 4-pole (≈1450 rpm) motors at 50Hz.
