The 21000 is the specification-grade potable water pump: the discharge casting and motor bracket are no-lead brass alloy, bracketing the stainless shell with corrosion-proof, lead-free castings. The threaded acetal check valve carries a 400 PSI working pressure and removes easily for service. A rubber discharge bearing surrounds the stainless shaft — self-lubricating, maintaining alignment in the harshest conditions. Peak capacity models at 5, 7, 10, 15, 20, and 25 GPM.

The 22000 is the value line for standard residential wells — reinforced thermoplastic motor bracket and discharge with a built-in guide bearing, wrapped around the same stainless steel shell, stainless shaft, and stainless motor coupling as its stainless siblings. Thermoplastic impellers and diffusers keep cost down without giving up the internal anti-spin check valve or Baker's stage-by-stage factory testing. 1/2 through 1 1/2 HP covers wells serving most households.

The 23000 hardens the domestic platform for aggressive water and long service intervals: heavy stainless steel shell threaded at both ends for field service, 300-series stainless easy-wrench discharge with a built-in safety eye, stainless motor bracket, and Baker's Diamond Design easy-out check valve — removable for maximum service convenience. The 7/16" 300-series stainless hex shaft is individually measured for straightness. Up to 5 HP reaches deeper set depths than the thermoplastic line.

The 25000 extends the thermoplastic value platform beyond the 22000's ceiling: the same 5–25 GPM flow classes, complete with Baker stainless steel motor and leads, but sized 1/2 through 2 HP — a half-horsepower more reach than the 22000 for deeper static levels or higher pressure settings on a budget-conscious build.

The 26000 is the flagship construction — the only Baker series where even the impellers and diffusers are stainless steel. 431 stainless shaft, all other metal parts 304 stainless, stainless suction screen, stainless discharge head with built-in check valve, and a motor bracket built to NEMA dimensional standards. Complete with motor and leads, in flow classes at 5, 10, 18, 25, 40, and 70 GPM, 1/2 through 5 HP as stocked (larger available on request). Rated for clean, non-corrosive, non-abrasive liquids to 140°F.

Standard submersibles pull water from above the motor and strand the last foot-plus of tank volume. The Bottom Suction pump inverts that: its intake draws from the bottom of the unit, delivering maximum drawdown without sacrificing longevity — and it passes solids up to 1/8", making it at home in rainwater collection, gray water, filtered effluent, and pond service as well as potable cisterns. Two-wire, 1/2 and 3/4 HP, 115V or 230V, installs vertical or horizontal, CSA listed.
