Grundfos CMBE is a complete packaged pressure-boosting system, not a bare pump. Each unit pairs a stainless-steel CME horizontal multistage pump and premium-efficiency IE5 motor with an integrated variable frequency drive, and arrives with the five-way fitting, integrated non-return valve, diaphragm tank, outlet pressure sensor and pressure gauge already fitted. A pressure sensor watches demand and the drive varies motor speed to hold a constant pressure in the pipe system — connect the pipes, plug it in, set the pressure on the panel, and it runs.
The range covers ten single-pump models serving up to 60 GPM and 325 ft of head, plus three CMBE TWIN systems that put two pumps in parallel on a common base with cascade control and automatic alternation. Watermain Supply stocks the U.S. 60 Hz range in 115 V and 230 V with engineering-led sizing to your fixture count, elevation and inlet pressure. Compare the models below, or call 1-888.510.4036 and we will size it for you. Genuine Grundfos equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial distributor.
Control It From Your Phone — Grundfos GO
Every CMBE is radio-enabled for the free Grundfos GO app: set functions, read status overviews, technical product information and live operating parameters from an iOS or Android device. Connection uses the Grundfos MI 301 radio module, which pairs the pump to your phone over Bluetooth — order it with the pump and commissioning takes minutes, not a laptop.
Grundfos GO is a free app from Grundfos Holding A/S. The MI 301 communication module is required for CMBE and is sold separately.
The CMBE Line
Two configurations of the same integrated-VFD system: one pump for domestic and light-commercial supply, or two in parallel with cascade control for larger buildings and standby duty.

CMBE Model Range
All ten U.S. 60 Hz models. Model numbers state nominal flow (m³/h) and max head (m) — a CMBE 3-62 is a 3 m³/h (13 GPM) nominal pump with 203 ft of head, and per the manufacturer curves and selection charts it serves up to about 26 GPM at reduced head. Power figures are maximum P1 input.

CMBE TWIN: Cascade Control & Alternation
What the twin system adds over two independent pumps, and why it matters in a building.
Cascade control
The system adapts to consumption by switching pumps on or off and varying the speed of those running, so it holds constant pressure using only the number of pumps the demand actually requires.
Automatic alternation
Running hours are distributed evenly. The system starts whichever pump has accumulated the fewest running hours since power was last switched off, so neither unit wears out ahead of the other.
Standby redundancy
Two independent pumps, each with its own drive, tank, sensor and check valve, on a shared manifold. If one is down, the building still has water — the reason CMBE TWIN suits hospitals and hotels.
Higher peak flow
Both pumps run together when demand calls for more flow than one can deliver at the set pressure, roughly doubling available flow at a given head compared with a single CMBE.
Wiring note. Single CMBE units ship with a 4.9 ft cable and a US plug. CMBE TWIN is intended for fuse-box connection and ships with a 15 ft cable and no plug — plan for an electrician on twin installations.
Sizing & Best Practices
How we size a CMBE, and the one limit that catches people out.
1. Calculate required boost
Required boost equals the pressure you want at the highest fixture, plus 0.433 psi for every foot of elevation from the pump to that fixture, plus friction loss in the piping, minus the pressure already available at the pump inlet. A three-story building wanting 45 psi at the top floor, 30 ft above the pump, with 30 psi at the main, needs roughly 45 + 13 + friction − 30 ≈ 28 psi of boost plus pipe losses.
2. Estimate peak flow honestly
Size to simultaneous demand, not the sum of every fixture. A water-supply-fixture-unit method (IPC Table 604.3 / Hunter’s curve) converts fixture counts into a realistic peak GPM for residential work; the IAPMO Water Demand Calculator is more accurate for light commercial. The CMBE 1 family suits small homes, the 3 and 5 families cover most multi-bath and small-commercial work, and the 10-54 serves up to about 60 GPM.
3. Check the suction condition first
CMBE is not self-priming. Maximum suction lift is 3.28 ft (1 m) including inlet-pipe pressure loss, so it wants a flooded or near-flooded suction from a main or a tank at or above pump level. If you are drawing up from a below-grade tank, cistern or shallow well, that is a job for the self-priming Grundfos SCALA line instead.
Sizing rules. Never set the pressure set point above the model’s maximum head — the panel allows it, the pump cannot deliver it. Keep the sum of inlet pressure and pump head under the 145 psi system limit, and if your duty point lands past 70 percent of a model’s maximum head at design flow, step up a model.
Grundfos Selection Charts
Grundfos publishes selection tables for residential work. Find your required boost in psi and your flow range, and read the recommended model — then confirm against the pump curve.

What Makes CMBE Different
The engineering behind the package, and why it matters on an installation.
Complete packaged system
Five-way fitting with integrated non-return valve, diaphragm tank, outlet pressure sensor and pressure gauge are fitted at the factory. Nothing to source separately, nothing to plumb but suction and discharge.
IE5 premium-efficiency motor
The MGE motor with integrated frequency converter is a premium-efficiency IE5 design; Grundfos rates the drive at up to 40 percent energy savings against fixed-speed boosting.
Stainless hydraulics
Pump sleeve, shaft, impellers, chambers and nozzle in AISI 304 stainless with an AISI 316 sensor fitting — corrosion resistance that suits chlorinated, softened and raw water alike.
Structured dry-run recovery
On loss of inlet pressure the pump stops and alarms, then attempts five restarts at 10-second intervals and eight at 5-minute intervals, repeating the cycle after 24 hours — it recovers on its own when water returns.
Wide model ladder
Ten models across four flow families mean the duty point can be matched closely instead of oversizing, from a small cottage supply to about 60 GPM.
Grundfos GO connectivity
Radio communication with the Grundfos GO app through the MI 301 module gives setup, status and operating parameters from a phone or tablet.
Simple setpoint control
The panel sets pressure with up/down buttons and light fields across the sensor range, so a service tech can change the set point without a laptop or a proprietary tool.
Drinking-water certified
Classified to NSF/ANSI 61 and NSF/ANSI 372 for potable water, and the 1 × 230 V CMBE models are UL listed as a packaged pumping system.
How CMBE Compares
We stock every major booster line, so we can be straight about fit. The single most important distinction: CMBE is a flooded-suction system, while most of the compact residential boosters below are self-priming.
CMBE vs Grundfos SCALA
| Specification | CMBE | SCALA2 | SCALA1 |
|---|---|---|---|
| Control | Variable speed | Variable speed | Fixed speed |
| Flow range | up to ~60 GPM | up to 18 GPM | 13-22 GPM |
| Max head | up to 325 ft | 147 ft | 150-180 ft |
| Models | 10 | 1 | 2 |
| Self-priming | No (max 3.28 ft lift) | Yes, 26 ft | Yes, 26 ft |
| Max system pressure | 145 psi | 145 psi | 116 psi |
| Hydraulics | Stainless AISI 304 | Aluminum + composite | Composite |
| Noise | ≤ 55 dB(A) | 44 dB(A) | < 55 dB(A) |
| Multi-pump | TWIN with cascade control | Parallel twin kit | Electronic twin |
| Typical use | Whole building, light commercial | Whole home comfort | Home, irrigation, transfer |
SCALA is the compact, self-priming, quieter choice for a single residence or a tank draw. CMBE is the larger, stainless, wider-ranging system for buildings — and the only Grundfos option here that reaches 60 GPM or 325 ft. If you need suction lift, choose SCALA.
CMBE vs DAB Esybox
| Specification | CMBE | DAB Esybox | DAB Esybox Max |
|---|---|---|---|
| Control | Variable speed | Variable speed | Variable speed |
| Max flow | up to ~60 GPM | 31.7 GPM | 76 GPM per unit |
| Max head | up to 325 ft | 213 ft | up to 316 ft |
| Self-priming | No | Yes, 26 ft | No (flooded via dock) |
| Max system pressure | 145 psi | 116 psi | 174 psi nominal |
| Hydraulics | Stainless AISI 304 | Composite/technopolymer | Stainless |
| Multi-pump | TWIN, cascade + alternation | Wireless to 4 units | 1-4 via Esydock |
| Phase | Single phase | Single phase | Single or three phase |
Esybox is the more compact, self-priming, plug-and-pump alternative and scales further with Esybox Max for commercial stations. CMBE counters with stainless hydraulics, a finer model ladder for close duty matching, and a higher system-pressure rating than the standard Esybox.
CMBE vs A.Y. McDonald DuraMAC
| Specification | CMBE | DuraMAC VS | DuraMAC Light Commercial |
|---|---|---|---|
| Control | Variable speed | Variable speed | Fixed speed |
| Flow | up to ~60 GPM | 6-35 GPM | 35 GPM |
| Boost / head | up to 325 ft | 25-65 psi | 40-78 psi |
| Max system pressure | 145 psi | 120 psi | — |
| Hydraulics | Stainless AISI 304 | SS 304/316 | Stainless components |
| Self-priming | No | Yes | Yes |
| Multi-pump | TWIN with cascade | Single | Single |
| Origin | Denmark / assembled Mexico & US | Made in USA | Made in USA |
DuraMAC is self-priming, domestically manufactured, and typically the lower-cost route to a residential VFD booster. CMBE goes higher on head and system pressure, offers ten models instead of two, and is the only one of the three with a factory twin system.
CMBE vs Goulds Water Technology
| Specification | CMBE | Goulds ResiBoost | Goulds Aquavar |
|---|---|---|---|
| Control | Variable speed | Variable speed | Variable speed (e-AB3 / e-AB2) |
| Max flow | up to ~60 GPM | up to 35 GPM | up to 80 GPM (e-AB2) |
| Motor | IE5, up to 2.31 HP P1 | 0.75-2 HP | 0.5-5 HP |
| Pump | Stainless CME multistage | Stainless e-HM | e-HM / MCS |
| Self-priming | No | No | No |
| Packaged | Fully assembled | Pre-wired, tank separate | Kit / drive package |
| Multi-pump | TWIN with cascade | Single | Duplex / multi-master |
| Install rating | IP55 pump, indoor | Indoor | NEMA 1 / NEMA 3R |
The closest architectural match on this page — both are stainless multistage VFD boosters that want flooded suction. Aquavar scales higher in horsepower and offers outdoor-rated enclosures; CMBE arrives fully assembled with tank and sensor fitted and adds a factory twin system.
CMBE vs Davey
| Specification | CMBE | Davey DD Series | Davey EvoDrive |
|---|---|---|---|
| Control | Variable speed | Variable speed | Variable speed (PM motor) |
| Max flow | up to ~60 GPM | 15-34 GPM | 28 GPM |
| Max pressure | up to 325 ft (~141 psi) | up to 91 psi set | up to 95 psi |
| Max casing / system | 145 psi | 116-145 psi | 145 psi |
| Self-priming | No | Limited | 13 ft lift |
| Hydraulics | Stainless AISI 304 | 304 stainless | 304 stainless |
| Multi-pump | TWIN, cascade + alternation | Daisy-chain 2 pumps | Duty/standby 2 pumps |
| Certifications | NSF 61/372, cULus | NSF 61 (WQA) | NSF-oriented |
Davey DD and EvoDrive are strong compact options with stainless hydraulics and simple two-pump modes. CMBE reaches substantially higher head, offers a wider model ladder, and its TWIN adds true cascade control and alternation rather than a simple pairing.
CMBE vs Franklin Electric
| Specification | CMBE | FE VersaBoost Pro | FE MH Series |
|---|---|---|---|
| Type | Packaged VFD booster | Packaged VFD booster | Multi-stage bare pump |
| Max flow | up to ~60 GPM | 18-25 GPM | 15-90 GPM |
| Max head | up to 325 ft | — | to 140 psi capability |
| Integrated tank / CV | Yes | Yes | No |
| Self-priming | No | No | No |
| Motor | IE5 with integrated VFD | Encapsulated 4 in submersible + VFD | Square-flange, 1 & 3-phase |
| Multi-pump | TWIN with cascade | Single | Build custom (SpecPAK) |
| Install rating | IP55, indoor | NEMA 3R indoor/outdoor | Indoor/outdoor motor |
VersaBoost Pro is the closest packaged competitor and adds an outdoor-rated NEMA 3R enclosure; CMBE offers far more models and higher head. MH Series is a bare pump for custom-built stations, and Franklin’s Inline SpecPAK sits above the CMBE class for duplex through quadplex commercial work.

Frequently Asked Questions
Common questions from plumbers, property managers and engineers specifying a CMBE booster.
Is the CMBE self-priming?
No. CMBE is designed for flooded suction, with a maximum suction lift of 3.28 ft (1 m) including inlet-pipe pressure loss. Feed it from a pressurized main or from a tank at or above pump level. If you need to lift water from a below-grade tank, cistern or shallow well, the self-priming Grundfos SCALA line is the correct choice.
Do I need a separate pressure tank?
No. Every CMBE ships with a diaphragm tank, five-way fitting with integrated non-return valve, outlet pressure sensor and pressure gauge already fitted. Connect suction and discharge, plug it in, and set the pressure.
What do the numbers in CMBE 3-62 mean?
The first number is rated flow in cubic metres per hour and the second is maximum head in metres. A CMBE 3-62 is a 3 m³/h (about 13 GPM) nominal pump with 62 m (203 ft) of head; per the manufacturer curves it serves up to about 26 GPM at reduced head. A CMBE 10-54 is 10 m³/h (44 GPM) nominal, serving up to about 60 GPM.
Which models run on 115 V?
Four models are offered in 1 × 115 V, 60 Hz: CMBE 1-44, 1-75, 3-30 and 3-51. Everything else in the range is 1 × 200-240 V. Single CMBE units ship with a 4.9 ft cable and a US plug.
What is the difference between CMBE and CMBE TWIN?
CMBE TWIN is two complete CMBE pumps mounted in parallel on a common base plate with a manifold set. It adds cascade control, which stages the second pump in as demand rises, and automatic alternation, which starts whichever pump has the fewest running hours. Three TWIN systems are offered: 1-44 and 3-51 at 115 V, and 10-54 at 200-240 V.
Does CMBE TWIN plug in like a single unit?
No. CMBE TWIN is intended for fuse-box connection and ships with a 15 ft cable and no plug, so plan for an electrician. Single CMBE units are plug-and-play.
How high can I set the pressure?
The set point must never exceed the pump’s maximum head, which is on the nameplate; the panel will let you set a value the pump cannot deliver. The pump also cuts in at 7.25 psi below the set point, and the sum of inlet pressure and pump head must stay under the 145 psi maximum system pressure.
Does CMBE need external motor protection?
No. Single-phase CMBE requires no external motor protection. The variable-speed MGE motor incorporates thermal protection against slow overloading and blocking, plus dry-running protection that stops the pump, alarms, and retries automatically when water returns.
Can I install a CMBE outdoors?
The pump carries an IP55 enclosure rating (sensor IP54) but Grundfos requires a protective cover for outdoor installation, large enough to shield the motor from direct sunlight, rain and snow. Ambient range is -4 to 131°F; provide freeze protection in cold climates.
Is CMBE certified for drinking water?
Yes. CMBE is classified to NSF/ANSI 61 for drinking water system components and NSF/ANSI 372 for low lead content. The 1 × 230 V CMBE models are additionally UL listed as a packaged pumping system.
