Our industrial high flow centrifugal swimming pool pumps are designed for a wide range of applications, typically used in large commercial pools and water parks where reliability is a must, these pumps are also suitable for industrial filtration and swimming pool cleaning equipment. Various construction materials available such as cast iron, stainless steel and bronze hence they can also be used for sea water applications.

These heavy-duty high capacity vertical swimming pool pumps come with high flow pre-filter baskets in either cast iron, bronze or stainless steel and are also available in a horizontal arrangement.

Due to its robust and functional design our industrial swimming pool pumps are highly efficient and reliable, they are also very easy to maintain as must models have a transparent lid on the top of the pre-filter basket meaning the operator can do a quick inspection of the filter without dismantling the pump or pre-filter, furthermore all our single phase swimming pool pumps come with thermal protection included as standard.

The NRV-FDN1500 vertical swimming pool pump range is fully compatible with sea water, salt ionizers and salt chlorinators as well as fresh water, this pump range comes with cataphoresis treated cast iron or bronze impellers and as a result these swimming pool pumps are more resistant to corrosion in comparison with the standard metal impellers from other manufacturers.

Another great advantage this industrial high flow swimming pool pumps have is their high hydraulic efficiency, meaning these pumps are much more economical to run than other swimming pool pumps as their energy consumption is a lot less.

Furthermore, our industrial vertical swimming pool pumps have been specifically designed to leave zero traces in the water whilst in operation therefore they are the perfect solution for aquariums or any other applications where marine life might be present.

The NRV-FDN 1500 pump range covers a flow rate of 10 to 556 m³/h

FAQS

Can this pump run dry?

No, definitely not! Centrifugal pumps will incur damage even after short periods of dry running. The mechanical seal will be destroyed, and this will cause the pump to leak. There is also the possibility that the motor will burn out. 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 water; 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 is correct for my swimming pool?

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.

Does my swimming pool pump need to be self-priming?

This depends on how the pump will be fed. If it is gravity fed from a tank, then a non-self-priming pump will be sufficient. However, if the pump is required to perform a suction lift from a sump, river or the ocean, then a self-priming pump will be required. If you are unsure, please do not hesitate to contact a member of our sales team for clarification.

Do I need a basket strainer with my pump?

A basket strainer is always recommended if there is a risk of any solids entering the pump during operation. If you are unsure, please do not hesitate to contact a member of our sales team for clarification.

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.
