Sewage Pumps

Handle the toughest residential and commercial wastewater jobs with Baker DuraMAC sewage pumps from Watermain Supply. Our sewage pump collection features rugged cast iron construction with non-clogging stainless steel vortex impellers that pass 2" solids without jamming — engineered for raw sewage, basement ejector pits, and lift station applications where failure is not an option.

Choose from standalone sewage pumps like the 5050CTSJ and 5050CVSJ with tethered or vertical float switches, high-volume models like the 5050CTSJ15 with cast iron and stainless steel construction, or complete pre-assembled sewage packages including the 5050CTSJPAC and 5050CTSJPAC24 that come ready to install with basin, pump, check valve, cover, and discharge piping all in one box.

We also carry side-discharge and alarm-equipped packages like the 5050CTSJPACSDA and 5050CTSJPACDA1 with NEMA-rated tank alarms for added protection against sewage backups, plus the 5050CTSJPACSL split-lid design for easy access and maintenance. For higher horsepower demands, our 405011SJ and 405012SJ series sewage pumps range from 1/2 HP to 2 HP in both 115V and 230V configurations with options for tethered switch, vertical switch, or no-switch for control panel installations.

Need to grind solids into slurry for long-distance pumping through small-diameter force mains? Our Baker grinder pumps deliver 1 to 2 HP of macerating power with 1-1/4" discharge connections designed for high-head, low-flow applications where standard sewage pumps can't reach. Every pump ships with a 1/2 HP continuous duty, thermally protected split capacitor motor, convenient carrying handle, and up to 80 GPM flow rates with vertical lifts up to 30 feet.

As an authorized Baker Water Systems dealer, Watermain Supply provides competitive pricing, expert sizing assistance, and fast nationwide shipping on every sewage pump, grinder pump, and complete sewage package in our inventory.
