Baker Submersible Pumps

Baker Water Systems has been engineering reliable water solutions since 1873, and their 4-inch submersible pump lineup reflects over 150 years of expertise in moving water from where it is to where you need it. Whether you're replacing a residential well pump, outfitting a higher-demand property, or setting up a cistern or agricultural system, Baker offers a complete range of submersible pumps from 1/2 HP through 10 HP with flow rates spanning 5 to 80 GPM across six distinct product series. Every pump features Baker's time-proven captured stack design with sand notches built into the diffusers — a detail that keeps abrasive particles moving through the pump instead of grinding it down, which translates directly to longer service life in real-world well conditions.

The lineup starts with the 21000 Series no-lead silicon bronze pumps for potable water applications, the 22000 Series thermoplastic pumps for budget-friendly residential wells, and the 23000 Series domestic stainless steel pumps that step up corrosion resistance with heavy-wall stainless shells and hex shafts for tougher water conditions. The 24000 Series covers the widest performance range in the catalog — standard stainless steel models handle 5 to 25 GPM with 1-1/4" discharge for residential and light commercial use, while the 24000 High Flow models push capacity up to 80 GPM with 2" discharge connections and horsepower options up to 10 HP for demanding commercial and agricultural installations. The 25000 Series thermoplastic pump ends offer an economical option for standard-duty applications, and the 26000 Series all-stainless-steel pump ends deliver maximum durability with 2" discharge for the toughest conditions. Baker also offers bottom suction pumps built specifically for cistern and tank applications, capable of handling solids up to 1/8 inch.

Every Baker submersible ships with an internal anti-spin check valve, corrosion-resistant stainless steel hardware, and is individually tested before leaving the factory. Pair any pump end with Baker's own 4-inch submersible motors — available in two-wire and three-wire configurations, single and three phase — along with matching control boxes, AutoDRIVE VFDs, and starter kits for a complete, factory-matched system. As an authorized Baker dealer, Watermain Supply stocks the full range and can help you select the right pump, motor, and controls for your specific well depth, flow requirements, and electrical setup.
