Selecting the right pump for a commercial building is crucial for efficient water management, heating, and cooling systems. The right pump can help reduce energy costs, keep the building running smoothly, and ensure comfort for everyone inside.

With various pump options available, it’s important to understand each type and assess your building’s specific needs. This guide covers the key factors to consider when choosing a pump for commercial buildings, helping you make a smart and cost-effective choice.

Understanding Pump Types

Various types of pumps serve different purposes in commercial buildings. Understanding these types helps in making an informed decision.

Centrifugal Pumps

These are the most common in commercial buildings. They move water by converting rotational kinetic energy into hydrodynamic energy. They are suitable for water supply, heating, and cooling systems.

Submersible Pumps

Submersible Pumps are designed to operate while submerged in the fluid they are pumping. They are ideal for drainage, sewage pumping, and flood control in commercial buildings.

Booster Pumps

These pumps increase water pressure in systems where it is insufficient. They are essential in high-rise buildings to ensure adequate water pressure at all levels.

Assessing Building Requirements

Each commercial building has unique requirements. Assessing these helps in selecting the most suitable pump.

Water Demand

Calculate the building’s total water demand by accounting for all uses, including potable water, heating, and cooling systems. This calculation ensures the selected pump can handle the required volume without overloading, considering both average and peak demand scenarios.

Pressure Requirements

Determine the pressure needed to deliver water effectively throughout the building. This is especially important in high-rise buildings, where maintaining adequate pressure across multiple floors can be challenging. The selected pump must sustain the necessary pressure to ensure all occupants have access to sufficient water pressure.

Flow Rate

Identify the flow rate necessary for the building’s systems by evaluating the peak demand periods. The pump must handle these peak flow rates without compromising performance, ensuring reliable operation during high-demand times.

Fluid Type

Consider the type of fluid the pump will handle. Different fluids, such as water, sewage, and chemicals, have varying properties that affect pump selection. Corrosive or abrasive fluids may require pumps made from specialised materials.

Energy Efficiency

Energy efficiency is a crucial factor. Pumps often run continuously in commercial buildings, so selecting an energy-efficient model reduces operational costs and environmental impact.

Pump Efficiency

Look for pumps with high efficiency ratings. Centrifugal pumps are generally efficient for water applications, providing good performance while consuming less energy.

Variable Speed Drives (VSD)

Pumps equipped with VSDs can adjust their speed based on demand, which significantly reduces energy consumption. VSDs are particularly useful in variable-load applications such as heating and cooling systems, where demand fluctuates.

Energy-Efficient Motors

Ensure the pump uses an energy-efficient motor. These motors consume less power and have a longer lifespan, which further reduces energy bills and maintenance costs over time.

Installation and Maintenance

Proper installation and maintenance are vital for pump longevity and performance.

Professional Installation 

Hire qualified professionals to install the pump. Proper installation prevents issues such as misalignment and vibration, which can cause premature wear and failure.

Maintenance Plan

Develop a regular maintenance plan. Routine checks and servicing prevent unexpected breakdowns and extend the pump’s lifespan. Include checks for leaks, noise, and vibration in the maintenance schedule.

Access to Parts and Service

Choose pumps from manufacturers with readily available spare parts such as APT Water. This ensures quick repairs and reduces downtime.

Cost Considerations

While initial cost is a consideration, look at the total cost of ownership, including installation, energy consumption, maintenance, and lifespan.

Initial Cost

Compare the initial purchase price of different pumps. It’s important to consider the initial cost but avoid making your decision solely based on this factor. Other long-term costs should also be taken into account.

Energy Costs

Consider the pump’s energy consumption. More efficient pumps may have a higher upfront cost, but they can save money in the long run due to significantly lower energy bills. This makes them a more cost-effective choice over time.

Maintenance Costs 

Evaluate the expected maintenance costs. Some pumps require more frequent servicing, which can increase overall costs. Choosing a pump with lower maintenance requirements can lead to substantial savings and fewer disruptions. Selecting a pump from a reputable supplier like APT Water ensures access to high-quality products that are less likely to need unplanned maintenance. 


Consider the expected lifespan of the pump. Investing in a durable, high-quality pump can be more cost-effective over time. A longer lifespan reduces the need for frequent replacements, thereby lowering the total cost of ownership.

Compliance and Standards

Ensure the pump complies with relevant standards and regulations in Western Australia. This guarantees safety and reliability.

Building Codes

Check local building codes and regulations regarding pump installations. In Western Australia, this includes compliance with the Building Code of Australia (BCA) and any specific local council requirements. Adhering to these codes ensures safety and avoids legal issues.

Industry Standards

Look for pumps that meet industry standards, such as those set by Standards Australia (AS/NZS) and the International Organization for Standardization (ISO). These standards ensure the pump meets performance and safety criteria.


Choose pumps with certifications from recognised bodies such as WaterMark as this indicates that the pump has been tested and meets specific quality standards. APT Water is proud to be one of only two Watermark-certified pump supply companies in Perth.
