Close Coupled Centrifugal Pumps
Need help specifying the right centrifugal pump? Contact our pump experts today!
Close Coupled Centrifugal Pumps Trusted for Long Service Life
Thanks to their ability to efficiently handle water, the most pumped fluid in the world, centrifugal pumps account for the majority of pumps out in the market. So why choose Castle Pumps for your closed coupled centrifugal pump requirements? As well as over 15 years' experience specifying the right centrifugal pump for our customers' requirements, our range includes marine type approved models which are trusted by over 22,000 vessels for safety out at sea thanks to their quality construction and long life design. This proof of reliability makes them a popular choice for industrial applications involving water and light fuels. The beauty of our close coupled centrifugal pump range is that the models benefit from a lantern bracket, preventing the pumped fluid from entering the motor if the seal wears. Due to their compact design, close coupled centrifugal pumps are ideal for installation with limited space. Contact our technical pump experts today for help with your centrifugal pump selection.

FAQs
A centrifugal pump transfers the kinetic energy of the motor to the liquid by a spinning impeller. As the impeller rotates, it draws in fluid causing increased velocity that moves the fluid to the discharge point.
Single stage centrifugal pumps have one one impeller, wheras multistage pumps have more than one. As the number of impellers dictate the pump's pressure capabilities, single stage pumps are typically used where flow rate is more important than pressure, whereas multistage pumps are designed for higher pressure applications.
A vertical pump means that the motor is installed above the pump head as opposed to being level with it. As this makes a vertical pump's footprint smaller than an equivalent duty horizontal, they are typically used when space saving is key.
The biggest advantage is that centrifugal pumps have a simplistic design with fewer components, making them smaller and less expensive than a positive displacement pump of the same duty.
Centrifugal pumps are typically designed for pumping low viscosity, clean fluids such as water, chemicals and light fuels.
With the exception of our specially designed Azcue CA pump, centrifugal pumps are unable to self prime without the help of an additional electric or vaccuum assisted priming pump which we can supply. If the suction conditions of your installation require a self priming pump, it may be that we advise of another pumping techology that is more suited.
Generally speaking, centrifugal pumps due to their tight tolerances are designed for clean liquids but if a vortex or open impeller is selected some solids are able to be handled.

The flow rate of centrifugal pumps rapidly declines with an increase in viscosity duty to the internal friction. They are therefore typically designed for pumping low viscosity fluids such as water, chemicals and light fuels.
Unfortunately not. The high internal velocity/force that is applied upon the fluid by a centrifugal pump can damage or alter the consistency of a delicate fluid. Therefore, centrifugal pumps are designed for non-sensitive fluids such as water, light fuels and chemicals.
