Pumps are complex feats of engineering that are involved in nearly every aspect of modern life; always working away in the background so people rarely give them a second thought. Simple everyday tasks such as taking a shower, making a cup of coffee, or keeping an office warm all rely on pumps, and we’d be lost without them.
Here at Dutypoint Pumps we give a huge amount of thought to pumps so that other people don’t have to. We think about them in terms of optimisation, installation, energy consumption and customer requirements. This extensive knowledge about pumps helps us offer an unrivalled level of service and technical know-how to our customers.
Take energy efficiency, for example: today’s buildings account for 40% of the world’s energy use (that’s more than the carbon emissions of planes, trains, buses and cars combined). Most pumps do not need to run at full speed 24 hours a day – yet many do. Far too many of the pumps currently installed leave behind a serious carbon footprint, but by utilising more efficient pump technology we can help make a real difference in the fight against climate change, as well as saving money.
At Dutypoint Pumps we offer a vast range of pumps – from the popular to the obscure – and are committed to spreading the word about how pumps can help us save energy.
We go out of our way to ensure our customers find the perfect pump to meet their needs. Want to know more? Here is a rundown of some of the different types of pumps we have on offer:
Circulator pumps are specifically designed to circulate in a closed circuit. They are most commonly found in heating and cooling systems in both domestic households and commercial settings. Within the heating system circulators pump heated water from the boiler towards individual rooms and carry the cool water back to be reheated.
As the name would suggest, these pumps are designed to operate while submerged in water. Their use ranges from pumping sewage while allowing the free passage of solids, to borehole pumping or feeding irrigation systems in an agricultural setting.
These advanced multipurpose pumps have in-line connections, and can incorporate multiple impellers, pumping at high pressures if required. They can be used in a variety of applications, including water supply and treatment, irrigation and cooling water systems.
End suction pumps are one of the most common types of centrifugal pumps – and often the least expensive. These pumps use impellers to pressurise the pumped fluid.
These pumps produce output regardless of the speed at which they operate (much the same way a heart does). Take a hand soap dispenser as an example: it displaces a certain amount of fluid every time, even when pressed very slowly. Positive displacement pumps are used to pump viscous materials (such as oil, cake batter, or petrochemicals) that would change state if pumped with a centrifugal pump. They tend to run at much lower speeds to avoid altering the pumped medium.
A standard pump needs a net positive suction head to operate, but if a pump is above the liquid level it needs to self prime to draw water into the inlet. Self priming pumps can be used to pump water and light fuel, as well as liquids containing solids or with entrained air. Applications include flood relief, and firefighting.
The use of variable speed pumps play a vital role in energy conservation. For example, a pump that runs at 80% of its maximum speed uses 48% less energy than a pump running at full speed. Speed control systems can be used on new pump applications or retrofits in existing situations.
