Pump controls are designed to regulate the motors that provide power to electrical pumps, which can be done in a few different ways. One method is to make sure that the pump meets its minimum flow requirements by using a recirculation loop from the area being pumped, but you can also use a pump with a variable speed drive so its flow can be regulated. You can also control the flow of a pump by “throttling” the amount being discharged by opening and closing a valve at the exit end of the pump. They were developed as a way to minimize the amount of wasted energy being used in hydraulic systems, because they reduce the amount of power loss by making sure the relationship between pressure and flow can be regulated and adjusted according to various power levels.
How Pump Controls Work
The operation and mechanics of an electronic pump control are pretty straightforward. A device sends out a signal to an electronic driver board or amplifier card, and this low-current signal is amplified into a pulse-width-modulated signal that’s enough to power the pump. Solenoids or proportional pressure controllers (PPC’s) are used to convert the current to a force that’s proportional to what’s needed by controlling the pressure and flow of the pump.
Programmable units are the most widely used, because they offer more flexibility and efficiency. Programming pump controls aren’t that complicated, because their output settings are proportional to the input commands. It’s simply a matter of setting the voltage or current as well as the timing to whatever is needed, and setting up a new program is all you need if you want to change its operation. Some pump controls have certain presets that work right out of the box, which is often the case when purchasing a sump pump. But there are others that are meant to be used in specific applications and for specific requirements.
A pump control has to monitor the variables that are required to regulate and protect the pump, so its controls need to have the following:
- Motor Overloads — A safeguard in case the pump’s current goes above its “Full Load Amp rating.”
- Temperature Sensors — Protects the pump or motor if the temperature gets above a certain rating.
- Level Sensors — Protects the pump to make sure that it doesn’t run dry.
- Flow Sensors — Used to make sure that the pump is moving fluid.
- Pressure Sensors — Used to adjust the pump’s speed.
A pump control panel can be set up to operate more than one unit — whatever is needed for the situation.
