Features of Pressure Tanks
Pressure tanks are used in pressure systems to hold liquid pressurised. When a tap is turned on, the pump, the pressure switch in the system senses the pressure drop and water is drawn from the pressure tank. When the water runs out in the tank the pump will cut in and supply the water. The pump will continue to run after the tap is turned off to replenish the tank. All of this is governed by sensors in the pressure switch sensing pressure changes.
Short water usage, drips and leaks can all be taken up by the pressure tank without running the pump. This lengthens the life of the pump, reduces power consumption and eliminates pump noise if the pump doesn't need to run.
Not all tanks are equal however, not all are repairable. And selecting the right size tank is critical to your system functionality and the life of the tank.
Bigger is best when is comes to tanks. Buy the biggest you can afford and have room for. Consider only approximately 2/3rds of the tank's capacity is water held at pressure. So a 150L tank will hold around 100L at pressure. Your tank should hold approximately 1L per litre operating capacity of your pump.
Your pump operates at 50 LPM. Your tank operational capacity needs to be around 50L. Therefore you need at least an 80L tank (draw capacity approximately 53L).
