Whisper Pumps supply a range of high-quality multistage water pumps, suitable for transferring clean, low viscosity fluids in high pressure applications. Multistage pumps are centrifugal pumps with more than one impeller arranged in a series, which makes this pump type ideal for pressure boosting, as water is pumped from one impeller stage to the next, increasing the pressure.
Typical applications that multistage centrifugal pumps are suitable for:
► Irrigation systems
► Water treatment plants
► Heating and cooling systems
► Industrial washing equipment
► Domestic water supply
The beauty of multistage water pumps is that they can provide a precise pressure and head required for a specific application by simply selecting a pump with the correct number of stages (more stages the higher the pressure). This can be very beneficial for residential buildings such as tall apartment blocks where high pressure is needed for the water to reach its destination. Another benefit of our range of multistage centrifugal pumps is that we offer pumps with a compact design that can be installed horizontally or vertically.
Types of Multistage Pumps
Typically there are two types of multistage pump:
► Horizontal Multistage Pumps: These pumps are best suited to applications where particularly high pressure and flow are required, such as in industrial washing equipment and similar systems. Due to their construction, they can normally handle higher flow rates better than vertical models.
► Vertical Multistage Pumps: These models are still more than capable of producing high pressure but are more suitable for places where ground space is more limited. They can be used for a range of applications including boiler feeding, washing systems, cooling and air-conditioning, water supply and water treatment.
As a longstanding UK water pump supplier, Whisper Pumps have carefully handpicked multistage pump models from some of the world's leading manufacturers, Lowara, Ebara and Grundfos, based on their precise design and optimal performance in terms of flow and pressure. All of our multistage centrifugal pumps are designed with longevity and performance in mind; each is constructed from sturdy stainless steel to prevent abrasion and ensure reliable, long-lasting operation. Our range of multistage pumps also includes submersible multistage pumps that can be used to extract water from wells and tanks.
There is also a choice to be made between extended shaft versions and close coupled multistage pumps. The former are generally cheaper and more compact. However, close coupled versions allow for easier maintenance due to their interchangeable motors. The electric motors can easily be replaced without needing to disconnect pipework, or drain the pump.
