Double Suction Split Case Chiller Pumps | High-Capacity, High-Reliability Circulation by EKG (Malaysia) Sdn Bhd
Engineered for Demanding Chiller Plant Performance
Double suction split case pumps are the industrial-grade solution for large-capacity chiller circulation, designed to handle high flow rates with exceptional efficiency and reliability. Their balanced double-suction impeller design minimizes axial thrust, reducing bearing load and enabling smooth, continuous operation—making them the preferred choice for primary chilled water and condenser water service in major commercial, institutional, and district cooling plants across Malaysia.
High-Flow Capability: Ideal for large tonnage chillers (500+ RT) requiring substantial water volume.
Exceptional Efficiency: Optimized hydraulics and balanced impeller design result in superior energy performance at high flow rates.
Robust Reliability: Built for 24/7 continuous duty with heavy-duty shafts, oversized bearings, and rugged casings.
Easy Maintenance: Horizontal split case design allows full access to the impeller and bearings without disconnecting piping—minimizing service downtime.
Hydraulic Stability: Smooth, non-pulsating flow ensures stable chiller operation and control.
Primary Chilled Water Pumps: For large centrifugal, absorption, or screw chillers in district cooling plants, hospitals, and high-rise complexes.
Condenser Water Pumps: Handling high flow rates between large chillers and cooling tower arrays.
Primary-Secondary Interface Pumps: In large, complex hydronic systems with significant flow requirements.
Industrial Process Cooling: For large-scale manufacturing or data center cooling plants.
Hydraulic Engineering & Pump Selection:
Precise system curve analysis to select the optimal pump size and operating point.
Material specification: standard cast iron, bronze-fitted, or stainless steel based on water chemistry and system type (closed vs. open).
Supply of Engineered Pump Systems:
Providing complete pump packages including pump, high-efficiency motor (IE3/IE4), baseplate, coupling, and guard.
Customization with specific seal types, bearing configurations, and coating requirements.
Professional Installation & Commissioning:
Heavy-duty foundation design and grouting.
Precision laser alignment of pump and motor.
Proper piping design with adequate straight runs to ensure uniform flow into both suction eyes.
Advanced Control Integration:
Integration with Variable Frequency Drives (VFDs) for variable flow operation and energy savings.
Connection to Building Management Systems (BMS) for automated chiller plant sequencing.
Predictive Maintenance & Overhaul Services:
Vibration analysis and periodic performance testing.
Complete in-situ or workshop overhauls including impeller refurbishment, wear ring replacement, and dynamic balancing.
High Ambient Temperature Operation: Ensuring adequate motor cooling and material selection for condenser water service.
Water Quality Impact: Material compatibility with local water treatment chemicals and potential scaling.
Redundancy Requirements: Duty/standby configurations for mission-critical cooling plants.
Energy Efficiency Compliance: Meeting MS IEC 60034-30-1 motor efficiency standards and green building certification targets.
Heavy-Duty HVAC Expertise: We understand the requirements of large-scale chiller plants.
Lifecycle Performance Focus: We engineer solutions for long-term reliability and operating cost efficiency.
Technical Precision: Emphasis on correct hydraulic selection and installation quality.
Single-Source Accountability: Complete responsibility from design through to ongoing maintenance.
Local Project Experience: Successful installations in major Malaysian commercial and institutional projects.
High Operating Efficiency: Typically operate at 85-92% efficiency at design point.
VFD Retrofit Potential: Significant energy savings when converted to variable speed operation.
Long Service Life: 20+ year design life with proper maintenance.
Green Building Contribution: Supports GBI, LEED, and MyHIJAU certification goals.
