The most suitable fountain pump is the one that is 1.5 times the fountain’s head height. It worlds well when made to run 24 hours a day, to ensure best performance and functionality. Switching it on and off several times a day may be harmful for the pump in the long run.
Regular maintenance is necessary
Any fountain, whether in a public or private space, needs to get maintenance on a regular basis. If such fountains are outside the home, their pumps are located beneath ponds. Submersible pumps, as the names suggest, remain below the pond and regulate water flowing to the fountain pump every minute. Unless maintenance of the pump is given adequate importance, the fountain will not be able to last for a long time.
Purchase from a reputed company
While look to order outdoor fountain pump, be sure to consider only reputed vendors. There are many vendors available online, which means that a careful choice will have to be made. It would be a good idea to get in touch with relatives and friends, and also get recommendations through testimonials. Make it a point to speak to the neighbors in case they have similar arrangements.
Use of electricity
These days, there are options to buy solar fountain pumps as well. In today’s fast paced world, this is an innovation which gets rid of the use of electricity completely. On the other hand, there are still a number of pumps that run on electricity. About twenty years ago these consumed a lot of power, but the ones being manufactured these days are more efficient. In other words, they take up lesser units of electricity than the earlier ones.
Top benefits of submersible pumps
- Submersible pumps create very little noise
- As they are already present in the water, they do not have to be primed
- Very little energy is required to send water to the pump as they are highly efficient
- There are some which can handle solids, while others are ideally meant for liquids
- Cavitation does not become a problem since no spike in pressure is ever experienced. This ie because as liquid does not pass through the pump.
- The pumps are budget friendly, which ensures that they are sold fast. People can beautify their gardens or the outdoor areas of their homes with these.
- The best fountain pumps are always user friendly. Manufacturing companies also have easy return policies so that in case of defects, they can be returned without inconvenience.
The list given above showcases only the advantages. There are a few disadvantages as well, which include the following:
- One pump will not be able to meet all needs
- They are liable to corrode quickly
Common terms with respect to fountain pumps
Flow rate- This is the amount of water pumped over a specified time period. It can be expressed in different ways, which include cubic meters per hour (m3/h) and liters per minute (l/min).
Pressure- This word is used to indicate the force with which water is being pumped up. Pressure is measured using the standard unit bar, although there is another way of measuring the same. This is known as meters of water column (mWC), whereby 10 mWC= 1 bar
Suction head- It is also referred to as static lift. It is capable of stating the depth of water which can be pumped by a submersible or surface pump.
Discharge head- The maximum height that to which the discharge pipe can reach after the pump is known as discharge head. It is measured in the unit ‘meters’.
Total Dynamic Head (TDH)- When the sum of the discharge and the suction heads is subtracted from the total friction losses (pressure losses due to lengths of pipes, bends, etc.), it is called TDH.
Water quality- Every motor or pump can handle only specific water types. A compromise on quality of the same could severely impact the pump on a long term basis. As per the size of particles it can handle, water quality is divided into three categories:
Black water- Suspended solids go up to sizes of 25 mm here
Grey water- Suspended solids here are smaller in size, up to 20 mm
Clean water- This is the best quality among all tree, having suspended solids lesser than 5 mm in size
Best tips for maintenance of pumps
The pump has to be used in the correct way for a long life. It would be helpful to see its user manual, if being used for the first time or if it is a new model. Best results can only be obtained only when the pump is below water. In the event that grit, dirt and debris, are found on the unit, cleaning must be done. As mentioned earlier the pump must keep running 24 hours a day.
