The key purpose of a water fountain pump is to supply a flow of water to fountains or aeration devices in residential, commercial, and industrial applications. These pumps can be used indoors and outdoors. Their parameters depend on the volume of water to be processed and the desired outcome.
Even though the operational principle of residential and industrial water fountain pumps is similar, their purposes are drastically different. Let’s discuss the distinctions between the two pump types in order to make the right choice for your project.
1) Purpose And Location
As mentioned above, the purpose of these two types differ. Decorative fountain pumps can be used in water features, ponds or garden fountains. They are designed for indoor and outdoor use. These pumps are often submersible. They are differentiated by how many litres they can pump per hour.
An industrial fountain pump is commonly used to aerate wastewater received from manufacturing water. They are also applicable for treating sewage or water for municipal use. Industrial water fountain pumps can also help remove algae build-up in stagnant water.
2) External vs. Submersible
Residential water fountain pumps are usually submersible. Fountain pumps for industrial purposes are generally external. Submersible pumps are easier to install and are often less expensive than their external counterparts.
External industrial water pumps are more complex machines, but provide more efficiency. Higher efficiency for larger water basins means lower operating costs. External pumps are designed to handle the backpressure associated with a pressurised external filter. They are also easier to maintain and longer lasting.
Dual-use pumps are available for garden ponds. They are submersible but can be used externally.
3) Delivery Rate
Both residential and industrial fountain water pumps come in different shapes, sizes, and delivery rates. However, industrial-type fountain pumps usually provide a higher delivery rate since they need to process a higher volume of water.
Purchasing an industrial pump for residential use may not be cost-efficient since decorative elements and fountains don’t need such a high water throughput rate. However, if you own a large koi pond, you may benefit from a submersible industrial fountain pump.
4) Pump Type
Most industrial fountain pumps work on centrifugal principles. The pump moves water using the centrifugal force pressure created by the impeller. The water is moved to an aerator or another fountain device to be sprayed from the surface. While on the surface, the water gathers oxygen and then falls back to the basin. Such aeration enables microbial action in the breakdown of wastewater.
Other pump types can be used for residential purposes. For example, some homeowners use sump pumps for their fountains. Others may opt for magnetic drive pond pumps.
