Often people think that only choosing the right pump would be enough for them to run their operations smoothly. However, people miss the fact that choosing the right impellers is also as important as selecting the right pump.
Now, when it comes to wastewater pumps, they perform a sort of behind-the-scenes and yet very critical job. This is why most of the people do not think about it. They are simply found in the lift stations as well as wastewater treatment plants doing their job every day.
However, on a day when a user comes across any kind of experienced wastewater operator and goes on to ask what they like/dislike wastewater about the pumps, the operator would have a must-have list of features. These would be features that would keep the station running.
Talking about sizing a wastewater pump!
When it comes to sizing a wastewater pump, it is like sizing a pump for a clean water application. The users need to know the application information. This would include things like flow, fluid type, head, installation orientation as well as space constraints.
However, with wastewater applications, there are a few other factors that should be considered. The biggest out of these is solids. When you think about fibrous materials like flushable wipes as well as rags, they lead to ragging issues in the lift stations as well as in wastewater plants.
Wastewater, as well as sewage-type impellers, are specifically designed for dealing with this issue. This blog would explain the types of solids-handling pumps as well as impeller types that would help the users in making a smart choice when they select a pump for a wastewater lift station application.
Talking about types of pumps!
Submersible pumps are the types of pumps that are designed for operating inside wastewater. A close-coupled sealed motor helps the pump to completely submerge. This eliminates the need for a separate dry-well. Eventually, that decreases installation costs.
These types of pumps typically feature dual oil-lubricated mechanical seals along with moisture sensing probes as well as an associated alarm relay.
This alarm works when it detects that there is water in the oil chamber. This kind of sensor helps in protecting against moisture entering the motor. It prevents issues by alerting the operator to seal the failure immediately. Since the submersible pumps are installed in wastewater wet wells, access to such pumps is limited. Hence, the operators must remove the pump through the guide rail system, for inspecting or for servicing the equipment.
Other than this, there are dry-pit pumps that are installed next to a wet well or sump and self-priming pumps that are an aboveground alternative to submersible or dry-pit pumps.
The types of impellers include semi-open impeller, vortex impeller, and an enclosed channel impeller.
When you’re selecting a wastewater pump, consider the application constraints as well as features that are needed in a pump system. You would need expert counseling for the same, or at least more information about it. For the same, reach out to us at www.darlingpumps.in or contact us at +91-99819-92833.
