Chilled water or a chiller pump system are typically inline or end suction centrifugal pumps for moving water around the chiller system, used for primary, secondary, constant, variable or as a shunt pump. A chilled water pump is the critical circulation component that keeps chilled water moving reliably through the system, maintaining stable temperatures across HVAC and process cooling applications.
Dura Pump supplies and installs high-performance chilled water pumps for commercial and industrial chiller systems. Our range includes energy-efficient models designed for continuous duty, providing reliable circulation in large HVAC and process cooling applications.

Description
A chilled water pump circulates cooled water between chillers, air handling units, and heat exchangers in a closed-loop system. Choosing the right chilled water pump helps maintain design flow rates, reduce energy consumption, and protect system performance over time. This constant circulation maintains the required temperature across the building or process equipment. Dura Pump’s CHW pumps are built to handle high flow rates, variable pressure conditions, and long operational life.
Chilled water or chiller pumps (often referred to as a chilled water pump in HVAC specifications) are one of the most widely used pump and are simple, effective and reliable. In a standard set up water enters the pump via a horizontal pipe, goes through the impeller and – using centrifugal force –is flung out a vertical discharge. These can be found with glanded or glandless motors, otherwise knowns as canned motors. Smaller canned inline pumps typically come as standard with motor mounted inverter drives Inline pumps are normally available in single or twin head, which can be configured to automatically swop duties.
These CHW pumps are available in stainless steel for applications where chemical is present.
ChHW pumps are used to overcome the resistance in the pipework and valves or to lift the water out of the hot or cold well and push through the chiller unit, cooling tower or system for cooling Old belt drive and fixed speed systems can be easily upgraded to new energy efficient systems with payback times from 6 to 36 months, depending on application. In addition to saving energy, this can be a cost effective way of upgrading your system. Let your energy savings pay for your upgrade.

We supply various types of pumps used in chilled water systems, including single-stage end suction pumps, vertical multistage pumps, and inline centrifugal models. Each configuration is selected based on system size, flow requirements, and installation footprint. If you need a chilled water pump for a new installation or upgrade, we’ll match the pump type and control approach to your system layout and duty point.
Our Chilled Water Pumps Brands
A chilled water pump circulates cooled water through a closed-loop system, transferring heat away from buildings or equipment. It forms the core of a chiller pump system, maintaining efficient temperature control in large-scale commercial and industrial environments.
Common types of pumps used in chilled water systems include end suction pumps, inline centrifugal pumps, and vertical multistage pumps. Each type is selected based on flow rate, pressure requirements, and installation layout.
A chiller pump system moves chilled water from the chiller to air handlers or fan coil units and back again. This continuous circulation removes heat from the building, helping maintain a consistent and energy-efficient cooling process.
A chiller pump and chilled water pump are often used interchangeably. Both circulate water in the cooling loop, though some systems also use dedicated condenser water pumps for heat rejection, while chilled water pumps handle the cooling side of the system.
Selecting the correct CHW pump depends on system size, pressure loss, and operational demand. Dura Pump’s engineering team specifies pumps to match your system’s design conditions, ensuring efficient flow, long-term reliability, and low running costs.
