The most annoying thing under the sun besides load-shedding is standing under the shower with low water pressure. Imagine really soapy hair… You`re standing there cold feet, itching frustrated, continuously rubbing your hair wanting desperately to rinse the soap OFF. LOW water pressure is mad irritating. If you are experiencing low water pressure whether municipal or self harvested then forget about washing your dogs or filling the pool. That will be a dehydrating nightmare.
After my own ordeal, I did about a tonne of research and made plenty of testing until I eventually came to the main source of my pain. My water pressure wasn’t meeting the demand. If someone turned on the kitchen sink tap to rinse a cup, the water flow in the shower would come to a hissing halt.
Solution
The solution to my problem was a new water pump. I then discovered during my research that there many different types of water pumps and brands . In this article, I will talk about two types of pumps.
Peripheral Pump
Externally, Peripheral Pumps and Centrifugal Pumps generally look alike. What sets them aside is the internal construction. For Peripheral Pumps, their internal components work together to develop high discharge heads at really low flow rates. Peripheral pumps require careful calculations of the maximum pressures they can handle which can develop at zero flow conditions. The good thing is that extreme electrical and pressure overloads are easily prevented by suitable bypasses and relief valves featured on the pump. Extra consideration is also required in specifying control valve pressure drops due to the characteristic steep Head-Capacity curve.
Centrifugal Pump
The centrifugal pump is the most frequently used process pump utilized in the majority of installations. Centrifugal pumps are unanimously used because their buying price and maintenance cost are relatively very low. They are simple to operate, they provide a non-pulsating flow that is easy to control using a number of pre-set ranges, and they are suitable for clean, abrasive, corrosive or non-lubricating fluids. Lastly, Centrifugal pumps are generally quiet, adaptable to motor, turbine or engine drives and can be obtained in a wide capacity-head range to handle fluids varying in temperature.
Eventually, I made my pick, now pick yours.
Bottom line:
Which pump should you buy between centrifugal and peripheral?
Answer: The one thing to keep in mind is that wattage matters, the higher the watts the high the pressure served. It doesn’t really matter because the centrifugal pump is highly recommended for pumping clean, non-aggressive water. The pump range is reliable, maintenance-free and widely used in the domestic and civil sectors for water distribution in combination with small pressure and flow controlled applications, used in general and for garden irrigation. The pump must be installed in a closed, protected environment, avoiding direct rain or water spray.
On the other hand, the peripheral pump is recommended for pumping chemically non-aggressive clean water containing no abrasive particles. Suitable for reliable, simple and economical domestic use. Particularly suitable in combination with pressure or flow control for garden irrigation
