North Ridge Chemical pumps are heavy duty pumps designed for handling acids, highly corrosive chemicals and hazardous liquids in general, our NR chemical pump range has over 17 different pump types, with a wide choice of high grade chemical resistant construction materials such as PP, PVDF, AISI & ASTM 316 Stainless Steel and TITANIUM.

Due their great chemical resistance and vast pump range NR pumps can be used for wide range of liquids, some of the most common applications are chemical transfer, water treatment, detergent products, and fuel transfer.

NR Chemical Pump Rage is as follows:

Magnetic Drive Centrifugal Pumps

Magnetic Turbine Pumps

Magnetic Rotary Vane Pumps

Mechanically Sealed Centrifugal Pumps

Liquid Ring Vacuum Pumps

Vertical Immersion Centrifugal Pumps

*Self-priming Mag. Drive Pumps are also available*

The NR-HTM-V pump range are vertical cantilever centrifugal pumps, also called vertical immersion centrifugal pumps, these pumps are manufactured in Polypropylene or PVDF, these pumps are suitable for corrosive liquids.

NR-HTM-V pumps are magnetic drive vertical immersion centrifugal pumps designed for handling highly corrosive and hazardous liquids, these pumps are seal-less meaning they don't have a mechanical seal, the liquid is contained within the coupling chamber and as a result preventing fluid emissions and leakage of liquids, besides being incredibly safe, mag. drive pumps are also a waste-free meaning zero losses of the product being pumped as the liquid is always contained within the pump, these pumps are therefore an ideal solution for handling expensive, flammable and toxic chemicals.

Another great feature on these pumps is the fact they don't require any motor/pump alignment as having an internal magnetic coupling design prevents any shaft misalignments. Our NR-HTM pump range complies with all the European environmental and safety regulations and manufacturing standards.

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.
