Reliable, efficient circulation for chiller evaporator and condenser loops.
End suction centrifugal pumps are the most common and cost-effective choice for circulating water through chiller systems. Their robust, single-stage design offers dependable performance for both chilled water and condenser water service. EKG Malaysia supplies, installs, and maintains these pumps, ensuring they are correctly sized and configured for optimal chiller plant efficiency and longevity.
Why It's the Go-To Choice for Chillers:
Proven Reliability: Simple mechanical design with minimal failure points, ideal for continuous 24/7 operation.
Cost-Effectiveness: Lower initial and maintenance costs compared to more complex pump types for equivalent duties.
Space Efficiency: Compact footprint saves valuable plant room space.
Broad Performance Range: Available to match the flow and head requirements of most commercial and industrial chillers.
Easy Maintenance: Front pull-out design allows inspection of seals and bearings without disconnecting piping.
Critical Selection Criteria for Chiller Duty:
Correct Hydraulic Match: The pump must be selected to operate at or near its Best Efficiency Point (BEP) on the actual system curve, not just the chiller's nameplate flow.
Material Compatibility:
Chilled Water Pumps: Typically cast iron with bronze-fitted internals for closed, treated loops.
Condenser Water Pumps: Often require upgraded materials (e.g., bronze or stainless steel impellers/shafts) to handle raw or treated tower water.
Motor & Drive Specification: High-efficiency (IE3/IE4) motors are standard. Integration with a Variable Frequency Drive (VFD) is highly recommended for variable primary flow systems or for energy savings in secondary systems.
NPSH Margin: Ensuring sufficient Net Positive Suction Head Available (NPSHa) to prevent cavitation, which is critical for pump and chiller tube longevity.
Our End Suction Pump Service for Chillers:
System Analysis & Pump Selection: We calculate the total dynamic head (including chiller pressure drop, piping, valves, and fittings) to specify the exact pump model.
Professional Installation & Alignment: Precision laser alignment to the motor is crucial to prevent vibration, seal wear, and bearing failure.
Commissioning & Balancing: We verify flow rates, pressures, and electrical parameters to ensure the chiller receives its design flow.
Maintenance & Support: Scheduled inspections, seal replacements, and performance checks to maintain optimal operation.
A reliable partner for your chiller's performance.
The right end suction pump ensures efficient heat transfer, protects your chiller investment, and minimizes lifetime operating costs.
