Applications

The Right Pump for the Application

Rock City Machine Company has been supplying pump solutions across Middle Tennessee since 1902, and sewage and wastewater systems rank among the most critical equipment we handle.

Sewage and wastewater pumps aren't interchangeable. The type of solids present, the required flow rate, the lift distance, and the installation environment all determine which pump design belongs in a given application.

From Single Pumps to Complete Systems

Some customers need a direct replacement for a pump that's reached the end of its service life. Others are building a new system from scratch or upgrading something that was undersized from the start. Our sewage and wastewater offerings include:

Individual replacement pumps sized to match existing installations
Duplex and simplex pump stations for residential and light commercial use, with quadplex systems also available
Packaged wastewater pump systems with controls, floats, and enclosures
Wet well and lift station components and accessories

You can also learn more about our broader water pump and pump systems service for ongoing maintenance and repair needs.

Who We Serve

Residential customers

Typically need sewage ejector pumps for below-grade bathrooms, laundry rooms, or basement fixtures that can't gravity-drain to the main sewer line. Grinder pump replacements for low-pressure sewer systems are also a common residential need.

Commercial and light industrial customers

Commercial and light industrial sites often require higher-capacity pumps, duplex pump stations for redundancy, or systems designed to handle greater solids loading from food service, manufacturing, or processing operations.

Municipal and utility customers

Utilities working on lift station upgrades or replacements benefit from our access to multiple manufacturers and our technical familiarity with wastewater infrastructure. For related needs, we also carry sump pumps and sump pump systems and water pressure booster pumps.

Brands We Carry

Proven Manufacturers

Stocking this range of manufacturers means we can match the pump and control panel to the actual solids loading rather than defaulting to a single brand.
