DuraMAC Commercial — 35 GPM at 40 / 62 / 78 PSI Boost
For light commercial: restaurants, small offices, clinics, retail buildings, irrigation. Three workhorse models — 17040C035PC2, 17062C035PC2, and 17078C035PC2 — all delivering 35 GPM at 40, 62, and 78 PSI of boost respectively on 230V power. Same proven all-stainless pump end and digital control as Residential, scaled up: 304 stainless impellers, 301 stainless casings, silicon carbide mechanical seals.
DuraMAC Dual-Mode — Modular, Simplex & Duplex Up to 120 GPM
Commercial-grade flow with built-in redundancy. Dual-Mode delivers up to 70 GPM in modular and simplex configurations, 120 GPM in duplex. 2 HP TEFC single-phase motors, intelligent dual-mode control that operates in pressure-drop OR flow-sensing mode, stainless steel base, 20-gallon pressure tank on skid-mounted models, paddle switch for precise flow detection. Available in 44 PSI and 60 PSI boost across modular, simplex, and duplex platforms.
Why Dual-Mode for Commercial?
Pressure-drop mode — pump starts when pressure dips below setpoint. Standard for most water service. Flow-sensing mode — pump starts on detected flow regardless of pressure. Required where pressure can't be reliably read (e.g. rooftop tank-fed). Switch between modes on the controller. Duplex configuration provides 100% redundant backup — if one pump fails, the other carries full load while you service the failed unit.
DuraMAC Variable Speed (VFD) — Constant Pressure, Lower Power Bills
The most advanced pressure boosting technology Baker builds. IQ1000 controller with Yaskawa VFD ramps motor speed up and down based on real-time demand — maintaining rock-steady constant pressure while consuming only the energy needed at any given moment. Dramatically lower electricity costs vs. traditional constant-speed systems.

Why VFD Pays for Itself in 18–36 Months
Constant-speed boosters cycle on/off and run at full power even at low demand. A VFD only consumes the energy needed at any given flow. On a typical 5 HP commercial booster, VFD reduces energy consumption 30–50% — easily $1,500–$4,000/year savings on commercial electric rates. Add longer pump life (no hammering starts) and constant-pressure user experience, and the upfront premium pays back fast.

Why the Torrium² Matters
Traditional residential booster = pump + pressure switch + bladder tank. The pressure switch cycles the pump on/off based on a pressure range (e.g. 40–60 PSI), which means user experiences pressure swings every time the pump cycles. Torrium² eliminates the bladder tank entirely and uses electronic flow + pressure sensing to deliver constant pressure with zero swing — closer to a VFD experience at a fraction of the cost. Built-in dry-run protection automatically restarts after a fault.

Technical Reference
Booster Pump Sizing Guide
Most undersized booster failures trace to one mistake: sizing to "felt" demand instead of measured demand. Use these three methods to specify the right booster the first time.
Step 1 — Calculate Required Flow (GPM)
Rule-of-Thumb Method
3.5–5 GPM per home for residential. 2 GPM per fixture unit for commercial. Useful as a first-cut sanity check, but conservative. Always validate against fixture-unit method below.
→ Quick estimate
Hunter's Curve / Fixture Unit Method
Sum the WSFU (water supply fixture units) for all fixtures, then read GPM off Hunter's Curve. Industry standard for residential and small commercial. Account for simultaneous-use probability — fixtures don't all run at once.
→ Most accurate residential
AWWA M22 Method
For multi-family, hotels, hospitals, and large commercial. AWWA M22 manual provides demand curves accounting for occupancy patterns and peak vs average demand. Required spec on most municipal projects.
→ Commercial & institutional
⚠ Customer Estimates Are Almost Always Low
"I have a 4-bath house, I think I need 8 GPM" — actual peak demand for a 4-bath home is typically 12–18 GPM when shower + dishwasher + washing machine + irrigation can run together. When in doubt, size up. An oversized booster runs occasionally; an undersized booster runs constantly and burns out.
Step 2 — Calculate Required Boost (PSI)
Boost = Target Pressure − Inlet Pressure + Friction Losses + Elevation
| Component | Typical Value | Notes |
|---|---|---|
| Target pressure at fixture | 50–60 PSI | 60 PSI is standard residential code minimum |
| Friction loss in piping | 3–10 PSI | Long runs & ¾" copper add up — measure pipe length |
| Elevation lift (each floor) | ~5 PSI / 10 ft | 0.433 PSI per foot of vertical lift |
| Inlet pressure at meter | Measure with gauge | Don't trust the city's stated pressure — verify on-site |
| Example: Inlet 25 PSI, target 60 PSI at 2nd floor (10 ft up), 5 PSI piping loss → Boost = 60 − 25 + 5 + 5 = 45 PSI minimum → Specify 52 PSI Residential | ||
Step 3 — Match HP, Voltage, and Configuration
Need flow > 35 GPM? Skip 120V — go 230VBoost > 80 PSI? Multistage requiredNeed redundancy? Specify duplexVariable demand? VFD pays back fastSuction pressure unstable? Inlet PRV at 40–50 PSI
VFD & Inlet PRV — Setpoint Strategy
VFD systems handle pressure regulation downstream — outlet PRV is generally NOT needed since the VFD itself controls discharge pressure. Inlet PRV is recommended when supply pressure swings exceed ~30–40 PSI, set at 40–50 PSI to stabilize suction head. This protects the pump from cavitation during high-supply periods and ensures the VFD's NPSH calculations stay valid.
Why It Matters
VFD vs Constant Speed — Which One?
A common engineering question. The right answer is "VFD almost always" for any booster running more than a few hours a day — but the upfront math has to make sense. Here's the side-by-side.
Lower Upfront · Higher Operating Cost
Constant Speed
Single-speed pump + pressure switch + tank
- Upfront CostLowest
- Energy UseFull power on every cycle
- Pressure StabilityCycles between cut-in & cut-out
- Pump LifeHammered by frequent starts
- Sizing MarginMust oversize for peak demand
- Best ForLight/intermittent residential, low budget
- ExamplesBaker E-Series, McDonald, Davey HM
Higher Upfront · Pays Back · Best UX
Variable Speed
VFD-driven multistage with constant pressure
- Upfront CostPremium (15–40% more)
- Energy Use30–50% less than constant-speed
- Pressure StabilityRock-steady setpoint ±2 PSI
- Pump LifeSoft-start eliminates hammering
- Sizing MarginSelf-adjusts to load
- Best ForCommercial, high-rise, premium residential
- ExamplesBaker Micro VFD & IQ1000, Goulds AquaForce, Lowara BGM
Quick Payback Math
5 HP commercial booster running 8 hrs/day at $0.12/kWh: Constant-speed ≈ $1,750/year electricity. VFD at 60% average load ≈ $1,050/year. Annual savings ≈ $700. With ~$2,500 upfront premium for the VFD, payback ≈ 3.5 years. On 24-hr commercial loads, payback drops to under 18 months.

Technical FAQ
Common Questions
How do I know what size booster pump I need?
You need three numbers: (1) Required flow in GPM (use Hunter's Curve fixture-unit method, or 3.5–5 GPM/home rule of thumb); (2) Inlet pressure measured at the meter with a gauge (don't trust city-stated pressure); (3) Target pressure at the highest fixture, accounting for elevation (~5 PSI per 10 ft of lift) and friction losses. Subtract inlet from target + elevation + friction = required boost PSI. Call 281.664.8000 with these three numbers and we'll size it free.
What's the difference between Baker DuraMAC E-Series and Residential?
E-Series is the simplest plug-and-play unit — 120V, 1" NPT, no special wiring or programming. Residential adds smart digital control with three operating modes, a 2-gallon diaphragm tank, transducer monitoring, and TEFC motors for quieter operation. E-Series is for "I just want pressure"; Residential is for "I want pressure with a quality control system." Both are 304 SS internals and NSF-certified.
When should I buy a VFD booster instead of a constant-speed?
Buy VFD when: (1) the booster will run more than 4 hours/day; (2) you want constant pressure with no cycling; (3) the building is multi-floor or has variable demand; (4) you have a 3-phase power supply for higher HP. Skip VFD only when the booster is for an intermittent residential application where upfront cost matters more than long-term electricity savings.
Can I install a Baker DuraMAC residential booster myself?
Yes — DuraMAC residential models are designed for plumber-friendly installation. The 120V models (17035 and 17052 series) plug into a standard outlet. The 230V model (17070) requires a dedicated circuit and should be wired by an electrician. All units come with installation instructions; if you're doing your own plumbing work, you should be comfortable with NPT threading, pipe dope or PTFE tape, and basic shutoff/check valve sequencing on the suction side.
My pump is short-cycling. What's wrong?
Short-cycling (pump turning on and off rapidly) is almost always one of three issues: (1) Waterlogged pressure tank — the bladder has lost pre-charge, drain the tank and re-pressurize the air side to 2 PSI below cut-in setting; (2) Failed check valve — water is bleeding back through the system, replace the check valve; (3) Pressure switch differential too narrow — a wider cut-in/cut-out range gives the tank time to drawdown. If the booster is a VFD model and short-cycling, the discharge transducer is likely failing.
Are these boosters NSF certified for drinking water?
All Baker DuraMAC E-Series, Residential, Commercial, Dual-Mode, and VFD systems are NSF/ANSI/CAN 61 and 372 certified for safe potable water contact and lead-free compliance. Lowara e-HM and Goulds AquaForce/AquaBoost are also NSF-61 certified. Davey HM/HP series is internationally certified — check the specific model nameplate for current US certifications. A.Y. McDonald boosters are USA-made and NSF-certified.
Do I need a pressure tank with a VFD booster?
A small diaphragm tank (typically 2–5 gallons) is still recommended on most VFD boosters to absorb micro-flow demand and prevent the VFD from waking up for every dripping faucet. The IQ1000 series has built-in low-flow sleep logic that handles this electronically — but a small tank still smooths the system. For residential VFDs like Goulds AquaForce, the small tank is usually included. For larger commercial/industrial VFDs, the tank is sized to the application by your engineer.
What's the warranty on these boosters?
Baker DuraMAC: 2-year warranty on E-Series and Residential, 3-year on Commercial and Dual-Mode, 3-year on VFD systems (with extended option). A.Y. McDonald: 2-year. Davey: 2-year on HM/HP, 3-year on Torrium² controller. Lowara & Goulds: typically 1-year standard, with extended warranty options for commercial/industrial applications. We register the warranty with the factory at the time of shipment so you're covered without extra paperwork.
How fast can you ship a booster?
Stocked Baker DuraMAC residential and E-Series models ship same business day if ordered before 2 PM CT. Davey and A.Y. McDonald residential boosters ship same-day to next-business-day. Commercial Baker (Dual-Mode, VFD) typically ships within 1–3 business days. Lowara and Goulds quoted systems ship factory-direct in 1–3 weeks depending on configuration.
