1. What Type of Solids Are You Pumping?
As IFS is focusing on wastewater in this post, they assume the solids are non-abrasive (note that abrasive solids require a hard metal, agitator pump). Most likely, these non-abrasive solids are large and soft or long and stringy. You also need to know if the solids need to be reduced to go into your system or to discharge, or if you just need to pass them.
Large, soft solids generally require a shredder pump that will shear the materials before pumping. Long, stringy solids generally require vortex pump that can pass the entire solid.
Understanding the type of wastewater is also helpful. These are generally categorized as municipal (including sewage) or industrial. While municipal wastewater is generally consistent from site to site, industrial wastewater solids and contaminants often vary based on the type of industrial site.
2. What Solids Loading Can the Pump Handle?
In order to keep the solids moving with the liquid, there needs to be sufficient liquid either in the sump or in the system; otherwise, the pump will clog. Most solids handling pump designs can handle approximately 5% solids by volume. If your wastewater has a higher solids concentration, you will likely need to change the system to allow more water to accumulate in the sump or to add water to the process.
The sump pump basin size is also a factor. The basin should be sized to minimize the number of cycles per hour but cannot be so large that solids will settle instead of being brought into the pump.
3. How Might Your Piping System Affect the Wastewater Pump You Need?
Understanding the design of your piping system will help your provider ensure there are no areas where the solids may settle, build up and cause clogs. This includes:
In some instances, your provider may conduct an inspection. If the entire piping system isn’t visible, you may consider sharing the piping system plans or explaining where and how far the piping runs as well as explaining the piping connections and fittings.
4. What Is the Flow Rate Required for your System?
The flow rate is the amount of liquid that runs through the system in a given amount of time. The flow rate and pipe sizing determine the velocity needed to pass the solids downstream through the pipes. The flow rate also indicates if the sump Is properly sized. An undersized sump causes the pump to cycle too frequently and burn itself up.
If you don’t know your flow rate, here are two options to help your pump provider determine it:
Translating Answers into The Correct Pump Selection
The answers to these questions provides the information your provider needs to make a recommendation. The type of wastewater and solids determine the type of pump type – shredder pump or vortex pump. The flow rate and the amount of head in the system, will help determine the specific pump model required.
