Aquasol M011‑HP High-Pressure Safety Pressure Switch – 2–22 psi

The Aquasol M011‑HP Safety Pressure Switch is engineered for use in high-static-pressure aquatic systems—a perfect fit for installations where typical backwash return pressures reach or exceed 6 psi. Adjustable from 2 to 22 psi, it ensures chemical dosing is enabled only under proper pressure conditions, preventing feed during low flow or pump off events.

Built to Aquasol specification, the M011‑HP features a normally open switch, rated for 120 VAC at 12 A, and includes a ¼″ NPT pressure port with tubing adapter. Installation is straightforward, requiring only plug-in to the existing chemical feed line. When flow pressure drops or rises beyond set thresholds, the switch automatically shuts down dosing, resuming normal function once pressure stabilizes.

Backed by a one-year OEM warranty, this safety switch is ideal for commercial pools, water features, and elevated return applications.
