Regardless of the type of pump selected, choosing the right size of sewage pump is an essential step. Selecting a pump that is too small for the application leads to reduced life cycles, increased downtime, and increased operational costs as pumps are constantly repaired or replaced.
On the other hand, companies in New York using sewage pumps do not want to purchase pumps that are oversized for the application. This results in higher costs for the initial purchase combined with inefficiency in the pumping system that can also cause problems and cost money.
Ideally, buying from a company that offers support in choosing the right sewage pump for your application is a good decision. Look for companies that offer a top selection of leading pump brands, including Myers, Aurora, Wilo-EMU, and Vaughan.
Know the System Requirements
In most wastewater systems in and around New York, the commercial and industrial average sizes for solids is two and a half inches or more. The average waste solid requirement with residential systems is an inch and a half or more.
When replacing an existing pump, be sure to choose a discharge size and flow and total dynamic head size that is based on the water flow through the system in gallons per minute (GPU). The basic capacity or the holding tank must also be considered when choosing the right pump size.
Depending on the type of application, the sewage pump may also need to provide a grinding operation. Grinder pumps are used when the solids in the wastewater need to be ground into more of a slurry to move throughout the system.
In some cases, if large or dense objects are in the wastewater, shredder or cutter pumps may be required to break up plastics or other items that are present in the wastewater coming into the pump.
