Water pumps are used to move water from one point to another, and can be submersible or external. In order to ensure that water is available at sufficient pressure at all times, small pressure tanks are utilized, usually mounted adjacent to the pump, so that the pump (which senses changes in the pressure of the system caused by the flow of water) does not have to turn itself on and off every time someone opens a tap.
The Pentax CAB series is a self-priming centrifugal pump for water supplies (even if mixed with gas) in small and medium households and commercial settings.

FA Questions:
Question:
How can one prevent pump burnout?
Answer:
One must make sure that the pump is sized properly and the voltage powering the pump is rated the same as the pump and sufficient to handle the load. Do not use extension cords. Make sure the temperature of the liquid being pumped is within the rating of the pump. Finally, make sure that the system head is at least the minimum head that the pump is rated at. If your pump is pumping at a low or negative head you will be overloading the motor with each duty cycle and shorten the service life of the pump.
