Questions to Ask When Selecting Wastewater Pumps

Selecting the right wastewater pumps is important to your home or facility’s sewage treatment functionality and cost effectiveness. It also plays a direct role in ensuring proper sanitation in your residence or commercial complex. If you are just about to make a purchase, there is no better time than now to get acquainted with some of the most important things you need to know about making the right purchase. To that end, make sure to consider these questions before selecting your sewage pumps.

What type of liquid will the pump process?

Processing sewage or wastewater involves a lot of factors that must be calculated properly to make sure that the most appropriate pump is selected. These include certain characteristics of the liquid to be processed, such as:

  • Temperature
  • Viscosity
  • Vapor pressure
  • Shear sensitivity
  • Vapour pressure
  • Solids presence and concentration; and
  • Abrasiveness or non-abrasiveness

Depending on the above, your pump must be fashioned from the right materials to make sure that it can carry out its tasks well. After all, some materials are better rated for certain conditions than others. To verify whether a material is appropriate for the wastewater or sewage that it will handle, always check chemical compatibility charts or read the product manual properly before choosing.


What kind of functionality do you require?

If your wastewater treatment needs cannot make room for downtime, it is best to invest in high-performing equipment from the get-go. The initial costs may be higher, yes, but the investment will pay back for itself over time. Additionally, functionality can be maximised with the best type of available equipment. This is not only because better equipment come with better design and calibration; they are also engineered for meeting more specialised requirements.

If your needs are more regular, then there are plenty of less costly wastewater pumps that you can choose from. But even if they do not fetch as much, this does not mean that you should go for the least expensive of the bunch. Some models of centrifugal pumps, for instance, come with self-priming functionality at still reasonable prices.


What are the operational conditions that the pump will be subjected to?

Specific environmental conditions are also critical to selecting the right pump. If you will be operating the pump outdoors, as an example, making way for special installation considerations may be necessary to ensure the full functionality of the equipment even through inclement weather conditions.
