Municipal Wastewater

Municipal wastewater applications involve a network of sewer pipes and lift stations that are critical for transportation, collection and treatment of the wastewater.

The lift stations play an important role in collecting and transporting sewage from lower to higher elevations, ensuring the efficient flow of wastewater through the sewer system. A typical Municipal lift station may utilize either a chopper pump like Barnes Sithe Chopper or a solids handling pump like Barnes SH Series series to lift the wastewater toward treatment plants.

Once at the treatment facility, a combination of advanced processes are used to remove contaminants and transfer the treated water back to natural water sources. Pumps are the foundation in maintaining effective and reliable wastewater management.

Why Choose Barnes Municipal Wastewater Pumps?

Reduced Operating Costs

Barnes’ pumps with premium efficient envie3 motor will save operating costs through reduced energy consumption

System Flexibility

With a variety of mounting accessories and configuration options, our product portfolio can be retrofitted or adapted to fit into almost any application.

Eliminates FOG

Barnes municipal pump portfolio efficiently and systematically mitigates fats, oils, and grease build-up, preventing clogs and ensuring the unimpeded flow of waste through the system.

Municipal Pump Portfolio

One of the main issues plaguing customers has been and will continue to be the changing waste stream, and the need to handle increasing solids. Picking the right pump for your municipal needs can be difficult. The solids content in your application will have an effect on this decision. Click on each section in the image below to see what products CP&S offers for your solids handling needs for municipal applications.

Chopper Pumps

Our chopper platform features oil-filled or air-filled motor housings.

In the oil-filled offering, the oil acts as both a lubricant and coolant, circulating oil through the stator and housing as a heat conductor.

In the air-filled offering, envie3, the pump utilizes a glycol cooling system. This patent-pending cooling system gives envie3 the capability to operate in dry-pit applications and allows lift stations to be shallower. This feature as well as the high efficiency IE3 rating will save time, money, and resources.

There are benefits to both offerings that can be adapted for any need or application. The main difference between the oil filled chopper and air-filled chopper is how the motor is cooled. The slicing mechanism and wet end of the two models are identical to provide the long-lasting reliability of all Barnes products. Whether an oil filled chopper or an air-filled chopper better fits your application, you will experience cost and time savings.
