The XVI single stage process centrifugal vertical immersion pump can be used for many applications in the industrial and marine markets. This vertical cantilever pump is designed to transfer clean or slightly contaminated low to medium viscosity fluids without the presence of fibrous or solid particles. Common fluids pumped include fresh water, grey water, sea water and fuels (diesel, petrol and kerosene) and common applications include fuel transfer, chemical, energy plants, mining, fire fighting, irrigation, water supply, water treatment, pressurisation, grey water, dewatering, and marine.

The centrifugal cantilever pump head sits at the end of a column and is submerged in the fluid while the motor is dry and situated outside the fluid.

The single stage process centrifugal vertical immersion pump design has many benefits:

The discharge pipe on this cantilever pump is extended to above the baseplate to ensure easy installation on site.

Capable of high flow rates up to 800m³/hr and pressures up to 9.5 bar.

This sump pump can be supplied with a column length up to 4m for the most challenging of installations.

The motor is situated outside the fluid allowing higher temperature fluids to be pumped without concern of the motor overheating.

No shaft sealing is required on this sump pump, this significantly reduces maintenance costs and eliminates any concerns of seal failure.

The XVI single stage process centrifugal vertical immersion pump is also available in an Atex version for handling flammable fluids or being installed in a non-safe area.

FAQS

How do I know what column length is correct for my sump?

The column length is dictated by the depth of the sump/chamber, it needs to be long enough to reach the bottom of the tank but leave enough space for the fluid to enter the pump. The length is customisable and bespoke to your installation requirements. The column will be immersed in the fluid, while the motor will sit above the chamber is a dry area.

What are the benefits of an immersion pump over a submersible pump?

The main benefit of an immersion pump over a submersible pump is that the motor is situated in a dry area outside of the fluid. This allows the motor to be a much lower IP rating and reduces the risk of area fluid entering the motor and causing damage. The immersion pump itself is also customisable, it is available in a wider range of materials and performances, this makes it far more versatile for use with different fluids. Submersible pumps are also limited by the fluid temperature, the motor requires cooling from the fluid itself to stop overheating, this is typically limited to around 40 to 60°C, column pumps can handle fluids as high as 95°C.

How do I know what pump materials are correct for my application?

Firstly, always check the compatibility of the materials available against the fluid being pumped. The main materials to check are the pump casing, impeller, o-ring and mechanical seal. It may be that more than one material is suitable for your fluid and selection could be based on the application type. For instance; cast iron, bronze and stainless steel are all suitable for fresh water. If it is a simple transfer application, then the most cost-effective material cast iron will be best. However, if it is a sanitary application, then stainless steel or bronze are better choices.

What do the terms Atex and explosion proof mean and why are they so important?

ATEX is an abbreviation of “Atmospheres Explosibles”. It is a regulation set out by the European Union to ensure the safety of products that are used to handle flammable products or are installed in environments containing flammable gases, vapours, mists or combustible dusts. For instance, if the pump is being installed in an explosive environment, then only the motor needs to meet the Atex standard stopping it from causing a spark during operation and igniting the atmosphere. However, if the fluid being pumped is flammable, then the pump will also need to meet Atex standards to ensure that no sparks are caused inside the pump itself when the fluid goes through it. It is crucial that an Atex rated pump or motor are used for applications involving explosive environments or flammable fluids, using a non-Atex pump or motor in these situations is extremely dangerous and contravenes health and safety standards.
