Factory-assembled, packaged booster systems for steady water pressure in light-commercial and multi-unit buildings — configured simplex, duplex or modular and sized to your duty point.
DuraMAC Dual-Mode commercial boosters from A.Y. McDonald are complete packaged systems — pump, controls and integrated assembly delivered as a single skid, ready to set and connect. They deliver consistent water pressure for light-commercial buildings, apartments, restaurants, small hotels and similar multi-unit demand.
Compare the configurations below, then choose the system that matches your building from the products listed underneath. For larger commercial, high-rise or critical-redundancy applications, ask our engineering-led desk about vertical multistage and engineered booster options.
All three share the DuraMAC Dual-Mode platform. The difference is pump count and redundancy — match it to your building's demand profile, then select the system below.
| Configuration | Pumps | Redundancy | Best Fit |
|---|---|---|---|
| Simplex | Single pump | None (continuous duty) | Smaller buildings, steady predictable demand, budget-conscious installs |
| Duplex | Two pumps, lead/lag | Standby backup | Multi-unit and higher-demand buildings that need uptime and load sharing |
| Modular | Multiple, staged | Higher redundancy | Wider or variable flow ranges and buildings planning for growth |
Booster systems are sized to the building, not pulled off a shelf. Give us these and we'll confirm the right configuration, pump count and lead time.
Delivered as a complete factory-assembled system — set it, connect it and commission. No field assembly of components.
We size to your actual flow, pressure and building conditions — not catalog assumptions or guesswork.
Simplex, duplex or modular — we'll tell you which fits, and flag when a job needs an engineered system instead.
