Frequently Asked Questions (FAQs)
1. Can you restrict the flow of a submersible pump?
There's no difference between restricting the flow by using a valve on the output and restricting the flow by having to pump the water higher. Both just increase the head pressure and won't damage the pump. Restricting flow by putting a valve on the input can cause cavitation, which can damage the pump.
2. How do you reduce the flow rate of a pump?
You can reduce the pressure of a pump in two ways. Either you can reduce the speed of rotation of a pump, this can be reduced by reducing the power/ potential given to the impeller. Or by using small dia impeller so that it can cause less impact on pressure of a fluid.
3. How do you calculate the flow rate of a submersible pump?
Submersible pump flow calculation formula: 60HZ flow × 0.83 = 50HZ flow 60HZ lift × 0.69 = 50HZ lift 60HZ power ÷ 1.728 = 50HZ motor power motor output power = Q (flow) × H (head) / 367.2 / efficiency × 1.15 motor output power = shaft power × 1.15 pump efficiency = Q × H × 0.00272 / motor power Q represents flow; H ...
