When most people think about pump reliability, their first focus is the pump itself — impellers, casings, and materials of construction. But in many cases, motor performance is just as critical.

A common issue we see in the field is motor overheating, and it often comes down to poor temperature control rather than a mechanical failure. 

When selecting a pump, one of the key pieces of information provided by the supplier is the pump performance curve.

This curve shows how the pump will perform across different flow rates and pressures—but for many operators and engineers, it’s not always clear what point on that pump curv

There comes a time in every good pump systems’ life where what once was adequate is now not good enough.  The flow needs to increase, the lines get extended, or the operators just need that bit of extra momentum on the discharge.  As pump experts, this isn’t the end of the world, we have several levers we can pull to help get that extra bit of pressure out of the pump and increase discharge pressure of centrifugal pumps to meet the new systems requirements.

When purchasing a new pumping system, or upgrading an existing one, often the main considerations is the upfront cost of the pump itself.  Although the capital cost only equals about 10% of the lifetime costs, there are other factors, such as spare parts, downtime, operational costs, and maintenance which are all important  variables to consider. 

With over 40 years' experience working with a variety of industries, Global Pumps' share the common things to check for pump problems:

To maintain optimal pump performance for longer, it is important to service your pump regularly, and ensure it's accessible for regular servicing including: removing sections of pipe work, maintaining sufficient cooling around the pump and having the required space for lifting equipment.

Self-priming centrifugal pumps can be utilised in any application that standard centrifugal pumps are applied, but what makes them different is their ability to self-prime.

Is your pumping system the core of your process or production? If it is underperforming, you may not reach your operational objectives, impacting uptime, maintenance costs, and ultimately your business’s bottom line.

Pump curves fall into several categories and can represent different aspects of the pump’s performance. The most common types of pump curves include: pump family selection, the manufacturer’s published curve, certified pump curve and system curve.

Understanding the different parts that make up your pump allows you to implement effective and best-practice maintenance procedures.
