Centrifugal water pump information 

A Pedrollo centrifugal Water pump is available in many different sizes and designs.

Centrifugal pumps are any pumps with an impeller that spins on a shaft, exerting centrifugal force on the fluid and driving it outwards.

Pedrollo manufactures and has developed a number of designs to offer users choices when selecting a centrifugal pump for their specific application.

Certain centrifugal pumps are designed to provide huge flow rates at very low pressures or heads. These are normally known as single-stage pumps. See the Pedrollo CP, HF, NGA, and F series of pumps.

Other centrifugal pumps produce high heads at lower flow rates and are known as multistage pumps.

The multistage centrifugal water pump, Pedrollo 2 CP series, as well as the borehole pump SR range, being a submersible pump, are typical examples.

When selecting a pump, one obviously needs to have the basics in place before requesting or designing the right pump for your pumping systems.

Pressure pumps, for example, will need to take into consideration not only the system back pressure and the pump’s static head requirement, but also determine how much pressure is required at the end point.

Pumping systems

Typical pumping systems that need pressure at the outlet of the pipeline include domestic water supply, irrigation systems, and boiler feed pumps.

These pumping systems all require the water to not only be delivered to the end of the pipe at a specific flow rate, but the system must also provide excess pressure to drive the sprinkler, shower head, geyser, heat exchanger, cooling coil, etc.

When it comes to industrial pumps, the actual pump system can become complex, and one needs to involve a pump professional in the selection process.

The most common type of Centrifugal pump is termed an end-suction pump.

These centrifugal pumps are typical of Pedrollo’s F and CP series.

The CP and 2 CP series of centrifugal pumps have threaded inlet and outlet housings, whereas the F series has flange inlet and outlet ports.

Internationally, Pedrollo is known as the innovator of pumps for the water industry and prides itself on the quality of the centrifugal pumps manufactured in the Italian plant.

Through the design, casting, and machining of components in various materials, Pedrollo has developed products for the majority of water and process fluid systems for which centrifugal pumps are well suited.
