What To Look For When Buying A High-Volume Water Pump In The UK

Posted by James Jordan on Jan 31, 2019 1:05:00 PM


A high-volume water pump is a necessity for many complex and large-scale construction projects. The ability to deal with large volumes of water while not being stopped by debris can make a pump an irreplaceable assistant for many tasks.

Today, you can find numerous high volume water pumps for sale at a range of prices. Which one is the best for your project? Let’s take a look at several parameters you may want to consider when buying such a pump in the UK.


In the majority of cases, high-volume pumps are made of durable materials, such as heavy solid steel. If you are looking for a pump to stay on one site for the duration of a project, the weight can be overlooked.

However, if you need the pump to be portable, pay attention to its weight. Today, it’s possible to find a high-quality pump with a reasonable weight that can be transported in a van or flat-bed vehicle


High-volume water pumps need to be durable. They have to be manufactured from highly resistant materials and come with heavy-duty full frame protection. Weather-resistant materials are necessary for submersible pumps as well as those working in shallow water.

High-quality water pumps are equipped with silicon carbide mechanic seals. They are abrasion-resistant, making the pump last longer in harsh conditions.

Another component to look for is a cast iron volute. A volute is a special casing that creates pressure using energy from the impeller. The impeller pushes the water and/or solids into the volute to create enough pressure behind the water so it’s propelled toward the discharge point


The engine is one of the most important components of a high-volume water pump since it provides the power for the delivery volume. The quality of the engine depends on the manufacturer. Even though Honda Koshin engines are the most popular ones used in high-volume pumps today, they can be costly. Loncin, on the other hand, offers excellent quality with a reasonable price tag.

Pump Type

Many types of water pump types exist for different construction projects. If you are looking for a high-volume model, you may want to consider an axial flow pump. It’s a centrifugal pump that uses an impeller with vanes which channel the flow axially. That’s what makes it different from other centrifugal types, which channel the flow radially.

An axial pump creates less head than other types of centrifugal pump, while producing higher flow rates. They are excellent for flood dewatering applications, with a delivery volume that can reach up to 750,000 lph.

If you don’t need extremely high volume, you can opt for other centrifugal pump types, which can provide formidable results as well.
