Pumps are apparently simple devices, but there’s much more you will know about them when you scratch the surface. They are used everywhere, at home and in industrial settings. So it makes sense to know them better. Still, you probably take them for granted as everyone else does, even while they work silently and consistently to perform many tasks. But you will be surprised to know that pumps have a lot of interesting things about them. Let us highlight some for you.
They have a best operating point
Pumps are designed to give their best at one point, which is their best efficiency point (BEP). The point refers to the hydraulic condition of a single point of head and flow. If you settle for anything other than the best efficiency point, it is a sheer commercial compromise. It is best to choose the pump wisely because having one built for your unique set of hydraulic conditions can cost a lot.
Consider the published curve carefully
Typically, pump performance curves published by manufacturers are based on a standard. It is for clear water at 65 F, unless they state otherwise. But these are not corrected for pump performance factors such as fluid viscosity and specific gravity. You must consider these factors carefully to get a fair idea of the performance you can expect from the machine. It will require some calculations and knowledge, but you can seek professional advice for it.
Never operate it beyond the curve
An interesting fact, as well as advice, is to never extend beyond the performance curve. It sounds like a tempting thing to try, but you will end up with performance issues if you experiment. If a published curve stops at a certain point, there is a good reason for it. Trust the recommendation and ensure that you follow it when you operate the machine because it will deliver the best performance.
It does not suck fluid
A common misunderstanding about pumps is that they suck fluids, but it is only a myth. The pump is not the energy source that pulls the fluid. Instead, it happens due to the force of gravity or atmospheric pressure. Moreover, a fluid is devoid of tensile strength, so a pump cannot pull into the suction.
Do not expect plug-and-play for industrial pumps
It is best to have an expert install and set up the machine for industrial settings. There is much work to get the pump up and running. The professional will add oil to the bearing housings, align the driver, and recheck the alignment after installing the piping and grouting in the base. They will also ascertain the rotation and set the mechanical seal after installation. It is best to buy from a manufacturer that offers reliable after-sales services.
Now that you know these facts, you will understand that pumps are far more complex than you imagine. You will probably consider a lot of things the next time you buy one for your facility. Choose wisely, and you can avail of the best performance over the years.
