Description

Used to transport fluids by transforming rotational energy to hydrodynamic energy, centrifugal pumps are commonly used for water, sewage and petroleum. At Allflo Pumps & Equipment, our 70+ years of combined experience in the industry has given us the necessary expertise to manufacture high-quality centrifugal pumps that are built to last and able to deliver reliable performance for countless applications. Suitable for hot and cold water transfer, dewatering, effluent, machine cooling, air conditioning systems and more, you can rely on these pumps to provide the performance you need.

Features of Our Centrifugal Pumps

Our centrifugal pumps are available in a range of materials, with different mechanical seal options also available. Constructed to be compliant with ISO and DIN standards, they feature a back pull out design that allows for fast dismantling and re-assembly. Self-priming versions are also available for easier operation.

Features

These centrifugal pumps come in many different options. These pumps come in complete cast iron, stainless steel and even plastic pumps. The good thing about these types of pumps are that you can put them in parallel for more pressure or series to get more flow or have duty/standby operation.

Some important notes about centrifugal pumps:

The volute casing or chamber is where the impeller sits inside. Often the discharge and suction ports are moulded (cast) or contented to the volute in some way. Inside you will find where the impeller sits.

The bearing housing is another important part of the pump. You can get different types of bearing housings and with most manufacturers, they standardise on one or a few types for their whole range.

The seal type is another part that can cause a lot of fluid/product wastage and be a non-stop hassle for the user. The seal type has to be selected by a professional as there are different options available such as, mechanical and packed gland. But with the mechanical seals, you can get even more options such as cartridge style with or without flushing options or just standard rotating spring style. Different types of Materials are another option that is available. The most common materials are cast iron casing, bronze impeller and stainless steel shaft. But you can get either all stainless steel or all bronze.

When selecting a pump, you will need to know the following:

  • Fluid being pumped
  • Suctions lift or flooded suction
  • Discharge pressure or head (this takes into account the pipe size and length)
  • You will also need to understand how to read centrifugal pump curves

Motor Pumps

Motor pumps is another name for centrifugal pumps. It can refer to either having and electric motor or a petrol/diesel motor.

Impeller Pumps

This is a type of centrifugal pump which is popularly known to use impellers or rubber rotors with flexible oriented blades or vanes. The blades/vanes rub and bend against the eccentrically shaped casing where they rotate.

End Suction Pumps

An end suction pump is a type of centrifugal pump that comes with a casing where the suction comes in from one end and the discharge comes out from the top. They normally have one impeller and are always single stage pumps. They are one of the most common configurations found in centrifugal pumps.

Centrifugal Pump Designs

The centrifugal pump designs also plays a big part on how the centrifugal pump will perform. There are very many centrifugal pump designs all created to suite various needs. You should note that the designs vary with different types of centrifugal pumps such as horizontal multistage pumps, double suction pumps, regenerative pumps, self-priming pumps e.t.c.

There are many different styles and configurations available and are called or named differently by many manufacturers and users. Some of the names are:

  • Vertical centrifugal pump
  • Horizontal centrifugal pump
  • Pump centrifugal
  • End suctions centrifugal pump
  • Self priming centrifugal pump
  • ISO or DIN pumps
  • Circulation pump
  • Fluid pumps
  • Motor pumps
  • Impeller pumps
  • End suction pumps
