Maintaining Your Submersible Sewage Pumps

When it comes to pumps like submersible sewage pumps, everyone wants to just do their best to maintain them! However, lack of proper source of knowledge usually gets them at a place where it’s tough to execute it. Therefore, this blog has been created in order to help such wishers, to succeed with proper information and ease.

The submersible sewage pumps are the kind of pumps that are connected with the pump and their motor is submerged under the liquid. They are suitable for various occasions. For making the equipment last longer, one needs to know about the submersible sewage pumps’ techniques of maintenance.

Few of the critical aspects which needs to be looked into:

1. Determining the correct direction of the motor’s rotation:
In case of Submersible Sewage Pumps, direction of rotation of pumps is one important aspect. These days it is generally observed that lack of awareness in these aspects often leads to abnormal working of pump. It is important to ensure that pump is running in right direction, or else it can adversely affect its flow & current consumption often resulting in damage in winding.   

2. Preventing the power supply voltage from an abnormal start:
It is a known fact that the low-voltage power supply line is relatively long. Due to this, the end voltage of the line being too low becomes a common occurrence. In a case where the phase voltage is lower than normal the speed of the motor of the given submersible sewage pump goes down drastically. This results in abnormal heat up of motor or even burning of an winding.

3. Device for leakage maintenance:
A life-saving device helps with leakage maintenance of the submersible sewage pumps. As pump operates underwater, a simple leakage can lead to power loss and could even end up in an electric shock. If this device is installed, it will block the power supply of the submersible pump ensuring safety and preventing leakage when required.

The other things that one should consider are preventing frequent Start & Stops, not letting the submersible sewage pump work in overload condition for a long time, paying attention to normal maintenance by usually checking the motor current, etc. 

Follow these simple techniques and you’ll be good to go!

Basic Pump Facts That One Should Know

Whether it is about raw water pumps or any other pump, one can only be confident about operating them when he or she knows the basic facts about water pumps. Therefore, it is always a better idea to at least skim through these basic facts. For the convenience of those curious ones out there, we have curated a list of such facts in this blog. 

 

Please have a look at the following:

Water pumps don’t suck fluids:

In the world of pumps, this is a very common misunderstanding. People need to realize that there is some energy source other than the water pump itself, that should supply the energy that is required for the fluid to get to the water pump. This is simply because water pumps do not suck fluids. In normal cases, these sources can be atmospheric pressure and/or gravity. In the end, one needs to remember that the fluids don’t have tensile strength. This is the reason why water pumps do not have the capability of reaching out and pulling fluid into the suction.

The realistic suction lift is around 26 feet (maximum):
It’s already been stated in the previous fact, water pumps do not suck fluids. Now, if you’re at sea level, then the atmospheric pressure would be 14.7 pound per square inch absolute (psia).  This simply translates (multiply by 2.31) into around 33.9 feet of absolute head. One might have been able to lift cold water 33 feet if there was no vapor pressure or fluid friction working against the entire system. Unfortunately, in reality, the fluid friction, as well as the negative consequences of vapor pressure, would end up working against you and precluding the fluid lifts of much more than 26 feet.

Almost all of the pump’s problems take place on the suction side:
Unfortunately, there is another very common as well as a pervasive misunderstanding about the working of water pumps. When you imagine any pump system acting as three separate systems, you’ll be able to understand better. Now, imagine them troubleshooting issues out in the field. The pump, the suction system, as well as the system downstream of the pump all working together. Studies show that around 85 percent of the pump issues always occur on the suction side of the pump. Therefore, whenever you are in doubt, its always a great idea to start looking at the suction side for the solution.
