Baker Submersible Pump Ends

Baker Water Systems submersible pump ends give you the flexibility to build a pumping system matched precisely to your well conditions, flow requirements, and motor preferences. Rather than being locked into a pre-assembled unit, a standalone pump end lets you pair the right hydraulic performance with the right motor — whether you're doing a new installation, upgrading an existing pump end while keeping a good motor, or specifying a three-phase configuration for a commercial or agricultural application. Baker's pump end lineup spans 4-inch residential units starting at 1/2 HP all the way up to 10-inch commercial and municipal pump ends delivering 1,100 GPM at 250 HP, all built to NEMA dimensional standards for direct compatibility with Baker motors and other industry-standard submersible motors.

In the 4-inch category, Baker offers pump ends across multiple series to match your application and budget. The 22000 Series thermoplastic pump ends deliver reliable performance at an entry-level price point for standard residential wells, available from 5 to 25 GPM in 1/2 to 1-1/2 HP configurations with 1-1/4" discharge. The 24000 Series stainless steel pump ends cover the same 5-25 GPM range but with 304 stainless steel construction, Noryl impellers, and polycarbonate diffusers for superior corrosion resistance — and extend into the High Flow line at 35, 40, 55, 60, and 80 GPM with 2" discharge and horsepower options up to 10 HP for demanding commercial and agricultural applications. The 25000 Series thermoplastic pump ends offer an economical alternative with stainless steel shells and thermoplastic internals, while the 26000 Series all-stainless-steel pump ends represent the top of the line with high-efficiency stainless steel impellers and diffusers, flow rates from 5 to 70 GPM, and horsepower options from 1/2 to 10 HP. For large-scale commercial, industrial, and municipal installations, Baker's 6", 8", and 10" stainless steel pump ends deliver flow rates from 90 to 1,100 GPM with horsepower ranging from 3 to 250 HP — all constructed from 304 stainless steel with 431 stainless steel pump shafts and ANSI/NSF 61 certification for potable water applications.

Every Baker pump end ships with a built-in check valve, stainless steel cable guard, and all necessary mounting hardware. Each unit is individually tested before leaving the factory and built to NEMA standards for seamless pairing with Baker's own submersible motors, control boxes, AutoDRIVE VFDs, and starter kits.
