Top Considerations When Buying Submersible Bore Pumps For Domestic Use
Bore pumps are submersible pumps used to push water from bores for various applications, such as irrigation, washing or even drinking. Notably, bore pumps can be powered by either solar or electricity. When buying a bore pump for residential use, you need to consider factors, such as pressure needs, source of power, characteristics of the bore and volume of water to be delivered, among others. Here are some top considerations when buying submersible bore pumps for domestic use.
Pump Cavitation
One major problem with overhead bore pumps is cavitation. A drop in water pressure can cause air bubbles in a pump, leading to excess noise and overconsumption of energy. The worst-case scenario is that cavitation can damage your pump. Therefore, a bore pump that is submerged in water reduces the cavitation problem because there is no sudden drop in pressure. Investing in submersible bore pumps is suitable for homeowners who wish to have a constant supply of water without incurring high maintenance costs.
Protection Against Water Damage and Electrical Failure
When you want to buy a submersible pump for your bore, always choose high-quality models with protection against entry of water since the pump is installed underwater. High-grade mechanical seals can prevent the ingress of water into the motor. When water penetrates a pump, it can cause electrical failure, which is the most common cause of submersible pump malfunction. An electrical failure can also be caused by running a pump dry for extended periods or due to mechanical failure. Besides, when you use the wrong source voltage, then you are likely to damage your pump. For these reasons, a thermal motor protector can regulate the voltage and temperature of the motor and shut down power accordingly. Further, consider pumps with anti-wicking cable entrance to guarantee that no water reaches the motor.
Total Dynamic Head (TDH)
The total dynamic head (TDH) of a submersible pump refers to the vertical lift (static head) measured in feet or metres coupled with friction loss. Friction occurs as water flows from the bottom of the bore through pipes, valves and fittings, which must be accounted for when calculating TDH. Talk to your vendor or technician to help you determine the total dynamic head of a pump because the value ascertains the pumping efficiency of the unit you intend to buy. A pump should run within the maximum efficiency rating to reduce running costs, excessive vibrations and damage to components.
