Simple, efficient, and versatile fluid movement with one impeller.
A single stage centrifugal pump uses a single impeller to increase the pressure and velocity of a fluid, making it the most common, cost-effective, and maintenance-friendly pump design for a vast range of applications. EKG Malaysia supplies and installs these reliable pumps for HVAC, water supply, industrial transfer, and general service where moderate head and high flow are required.
Key Advantages & Design:
Simplicity & Reliability: One impeller, one shaft, one set of bearings and seals—minimizing potential failure points.
Cost-Effectiveness: Lower initial purchase and maintenance costs compared to multi-stage pumps.
Ease of Maintenance: Straightforward disassembly and parts replacement.
Wide Performance Range: Available for flows from a few m³/hr to over 1,000 m³/hr and heads up to ~150 meters (depending on size and speed).
Common Configurations: End-suction (most common) and horizontal split-case (for higher flows).
How It Works:
A motor spins a single impeller within a volute casing. Fluid enters the impeller eye axially, is accelerated radially by centrifugal force, and is discharged through the volute, where its velocity is converted into pressure.
Typical Applications:
HVAC: Chilled water, condenser water, and heating hot water circulation.
Building Services: Domestic water boosting, pressure maintenance.
Industrial Process: Coolant circulation, clean water transfer, light chemical duty.
Water & Irrigation: Supply from reservoirs, lakes, or wells.
General Transfer: Tank filling, dewatering (with self-priming variants).
Selection Considerations:
Head & Flow Requirements: The pump must be selected so its operating point falls within 80-110% of its Best Efficiency Point (BEP) for long life and efficiency.
Material Compatibility: Standard materials are cast iron with bronze fittings. Stainless steel construction is available for corrosive fluids.
Drive Options: Fixed speed (direct online) or variable speed (with VFD) for energy savings in variable demand systems.
