Cooling Tower Pump

The essential circulator for efficient heat rejection.
A cooling tower pump is specifically designed to circulate water from the tower basin to the heat source (chiller condenser, process heat exchanger) and back to the tower for cooling. EKG Malaysia supplies, installs, and maintains robust, corrosion-resistant pumps built to handle the demanding conditions of open-loop tower systems, including algae, scale, treatment chemicals, and variable operating loads.

Key Design & Performance Features:

• Corrosion & Abrasion Resistance: Constructed with bronze-fitted internals, stainless steel shafts, and often epoxy-coated or stainless steel casings to combat aggressive tower water chemistry.

• High Flow, Moderate Head: Sized to overcome system pressure drop (heat exchanger, piping, valves) and the static lift to the tower distribution system.

• Variable Load Capability: Often paired with a Variable Frequency Drive (VFD) to adjust flow with changing heat load or wet-bulb temperature, saving significant energy.

• Reliable Sealing: Mechanical seals selected for compatibility with water treatment chemicals (e.g., oxidizing biocides).

Typical Cooling Tower System Configurations:

1. Constant Flow: Traditional design; pump runs at fixed speed.

2. Variable Flow with VFD: Pump speed modulates based on condenser water temperature, tower approach, or chiller load for optimal efficiency.

3. Multiple Pumps (Duty/Standby): For critical systems requiring 100% redundancy.

Why Tower Pumps Are a Specialized Choice:

• Fluid Handling: Must tolerate suspended solids, biological growth, and varying pH.

• Suction Conditions: Often require careful NPSH analysis as they may draw from an open basin.

• System Interaction: Pump performance directly affects tower efficiency and chiller condenser pressure.

Our Cooling Tower Pump Services:

• System Analysis & Pump Selection: Calculating total dynamic head, including tower static lift, and selecting materials for your water chemistry.

• Energy Efficiency Upgrades: Retrofitting constant-speed systems with VFDs and advanced controls.

• Professional Installation: Ensuring proper piping, vortex-free suction, and alignment.

• Preventive Maintenance: Regular inspection, seal replacement, and performance checks to maintain efficiency and prevent unscheduled downtime.

Drive your tower's efficiency from the pump room.
The right pump ensures effective heat rejection, protects chillers, and minimizes water and energy use.
