The IM series of centrifugal chemical vertical immersion pump is designed to be installed within a tank or sump for the transfer of clean or dirty chemicals up to a viscosity of 500cp. There are 11 models of pump within this range and the various sizes can cover flow rates up to 75m³/hr and heads up to 38m. The open impeller design allows the largest model in the range to handle suspended solids up to 11mm.

 

The centrifugal sump 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 standard column lengths are 500mm, 800mm, 1000mm and 1250mm; other lengths are available on request.

 

The casing of this heavy duty chemical pump is constructed from solid block polypropylene or PVDF depending on application requirements. The solid block casing has no welds like other chemical immersion pumps, this makes it extremely resistant to the strongest of acids and alkalis as there are no weak points on the casing.

 

Applications for this chemical cantilever pump include; mechanical and metalworking industry, ceramic industry, wastewater treatment, textile industry, automotive industry, paint industry, cosmetic industry and the cleaning industry.

 

This chemical vertical immersion pump is available with an Atex zone 2 motor if required for operation in non-safe potentially flammable environments.

FAQS

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.
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.
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.
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.
Our immersion pumps can be supplied with level sensors, float switches and control panels to allow a completely automated pumping process.
