Booster Pumps

Solve low water pressure once and for all with Baker DuraMAC booster pumps from Watermain Supply — the most complete line of residential, commercial, and industrial pressure boosting systems available from a single manufacturer, and the number one product we sell for good reason.

Whether you're a homeowner tired of weak showers and slow-filling appliances, a plumber specifying a system for a multi-story building, or a facility manager designing redundant pressure boosting for a hospital, hotel, or apartment complex, DuraMAC has a system engineered precisely for your flow rate, pressure requirement, and budget.

The lineup starts with the E-Series booster pumps — the simplest plug-and-play solution for residential low pressure problems, delivering 35 or 52 PSI of boost at up to 20 GPM on standard 120V household power with no special wiring required, available in no-lead brass or all stainless steel construction, both certified to NSF/ANSI/CAN 61 and 372 for safe drinking water contact.

Step up to the DuraMAC Residential boosters for more demanding homes with the 17035R020PC1 (35 PSI boost, 120V), 17052R020PC1 (52 PSI boost, 120V), and 17070R020PC2 (70 PSI boost, 230V) — all featuring digital control with three modes of operation, built-in transducer monitoring, two-gallon diaphragm tank, no-lead brass check valve, dry-run protection, and TEFC motors for whisper-quiet operation, with a set-it-and-forget-it design that starts automatically when you open a faucet and shuts off when flow stops.

For light commercial applications like restaurants, small office buildings, and irrigation systems requiring higher flow, the 17040C035PC2, 17062C035PC2, and 17078C035PC2 deliver 35 GPM at 40, 62, and 78 PSI of boost respectively on 230V power, using the same proven all-stainless-steel pump end and digital control platform with 304 stainless steel impellers, 301 stainless steel casings, and silicon carbide mechanical seals.

When your application demands commercial-grade flow and built-in redundancy, the Dual-Mode series delivers up to 70 GPM in modular and simplex configurations and 120 GPM in duplex, with 2 HP TEFC single-phase motors, intelligent dual-mode control that operates in either pressure-drop or flow-sensing mode, stainless steel base, 20-gallon pressure tank on skid-mounted models, and paddle switch for precise flow detection — available in 44 PSI and 60 PSI boost configurations across modular, simplex, and duplex platforms.

At the top of the lineup, the DuraMAC Vertical Multistage Variable Speed (VFD) booster systems represent the most advanced pressure boosting technology Baker builds. These IQ1000-controlled systems use Yaskawa variable frequency drives to ramp motor speed up and down based on real-time system demand, maintaining rock-steady constant pressure while consuming only the energy needed at any given moment — dramatically cutting electricity costs compared to traditional constant-speed systems. The Micro VFD series covers 1-1/2 HP to 3 HP in simplex (20–40 GPM) and duplex (40–80 GPM) configurations with boost pressures from 66 PSI all the way up to 140 PSI, available in both 208-230V single-phase and three-phase, featuring 1-1/4" suction and discharge, discharge transducer, sleep mode with low-flow protection, automatic system restart, dry-run protection, and password-protected parameter settings.

The IQ1000 VFD series scales from 3 HP to 10 HP in simplex (80–140 GPM), duplex (160–280 GPM), and triplex (240–420 GPM) configurations with boost pressures from 56 PSI to 150 PSI on 208-230V three-phase power — featuring 2" NPT stainless steel manifolds, suction and discharge transducers, no-lead brass isolation ball valves, wafer check valves with soft seat, liquid-filled pressure gauges, fused disconnect, stainless steel base, NEMA 1 enclosure, and full date-and-time-stamped fault logging for every alarm event. Every

DuraMAC booster system is built with 304 stainless steel impellers and diffusers, 301 stainless steel pump casings, silicon carbide and carbon mechanical seals, no-lead brass connections throughout, and NSF/ANSI/CAN 61 and 372 certification for potable water compliance. We also stock the complete line of DuraMAC booster repair parts including control boxes, transducers, seal kits, tee assemblies, pressure gauges, check valves, Yaskawa drives, pump ends, TEFC motors, paddle switches, disconnect switches, and stainless steel flanges — so when your system needs service, one call to Watermain Supply gets the right part shipped the same day.
