Vertical multistage booster systems stack multiple impeller stages to build high pressure in a compact footprint, then pair that with variable-speed control to hold steady pressure as demand rises and falls through the day. The result is city-water feel and energy-efficient operation for buildings that can't tolerate pressure swings.

These systems come in two control tiers — Micro for entry-level commercial duty and IQ1000 for advanced control and larger demand — each available in simplex, duplex or triplex pump configurations. Compare them below, then choose the system that matches your building from the products listed underneath.
