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.

NR-HTTSP pumps are magnetic drive regenerative turbine self-priming pumps, also called peripheral self-priming pumps, these pumps are 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-HTTSP pump range complies with all the European environmental and safety regulations and manufacturing standards.

FAQS

What is a magnetic drive and what are the benefits?

A magnetic drive is a means of sealing a pump without the requirement of a mechanical seal. Magnets are used to transfer torque from the motor shaft to the shaft within the pump head. There are many benefits of sealing the pump in this fashion, including;
• A mechanical seal does not need to be regularly replaced due to wear and tear, this greatly reduces maintenance costs.
• A seal flush is not required for seal lubrication.
• The fluid is fully contained within the pump, this means there are zero chances of leakage. This is a great benefit when handling hazardous and corrosive products.

Can this pump run dry?

No, definitely not! Magnetic drive pumps will incur damage even after short periods of dry running. Our advice is to ensure that the pump has a flooded suction or always make sure that the pump casing and inlet pipe are filled with fluid; one way of ensuring this is to fit a check valve on the inlet line to stop water escaping when the pump is inactive. Another way of protecting the pump is to fit a dry running device, this will turn the pump off if it detects that no fluid is entering the pump. If you think that dry running is inevitable, then please speak to us and we will try to select a more suitable pump for your application.

How do I know what size pump and motor speed is correct for my application?

A clear picture of the pump system is required to make an accurate selection. The main pieces of information required include; a description of the application, bore of pipework, the fluid, flow rate and pressure/head. With these pieces of information, a pump can be sized correctly to ensure it delivers the required flow rate and pressure and that is also operates at its best efficiency point to lower lifetime costs. Knowing if the pump is running intermittently or continuously also allows the correct motor speed to be selected. For instance, a pump running continuously 24/7 will require a 4 pole motor rather than a 2 pole motor. Running the motor slower and oversizing the pump will reduce wear of the motor and the pump, therefore lowering maintenance costs during their lifetime.

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 and o-ring. It may be that more than one material is suitable for your fluid and selection could be based on the application type. If it is a simple transfer application with a clean less corrosive fluid, then the most cost-effective material will be best. However, if it involves more complex variables such as high temperature and the fluid is highly corrosive then other materials will need to be considered.

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.

What is NPSH and why is it so important?

NPSH is an acronym for Net Positive Suction Head. NPSH measures the absolute pressure present in a fluid.

There are two main ways that NPSH is expressed in a pump system
• NPSHa - This is the amount of Net Positive Suction Head available at the pump inlet. NPSHa demonstrates the amount of pressure acting on a fluid as it enters the pump. This measures the amount of pressure between the liquid staying in its current state and forming vapour bubbles (beginning to boil).
• NPSHr - This is the amount of Net Positive Suction Head that the pump requires to operate without experiencing the damaging effect of cavitation, thus causing a dramatic reduction in pump performance.

It is very important to pay attention to these values when making a pump selection. Selecting a pump that requires more NPSH than is available in your system will cause fast and long-lasting damage to the pump and thus you will incur large repair costs and downtime.

What does the term best efficiency point (BEP) mean and why is it so important?

The best efficiency point or BEP is a point along the pump performance curve that indicates where efficiency for the pump peaks. When selecting a pump, you must try and get as close to the BEP as possible to ensure that the pump is at maximum efficiency when operating. The closer to the BEP the pump is when operating, the lower the energy costs will be, thus saving significant amounts of money during the pump’s lifetime. Also, vibrations will be at their lowest meaning maintenance costs are lower and the lifespan of the pump is maximised. It is very important to pay attention to the BEP when your pump is selected, as an oversized or undersized pump could cost you significant amounts of money.
