Product Overview

An intelligent system

Mascontrol is the innovative product providing optimum control for electric pumps used in residential and commercial well, water conditioning irrigation and booster systems.

An intelligent mix of hydraulic and electronic engineering,Mascontrol monitors both pressure and flow and automatically controls pump operations.

Mascontrol eliminates the use of large expansion tanks needed with traditional systems. No plenum chambers to recharge, and no irritating variations in pressure and flow at the point of use.

Mascontrol also provides complete run-dry pump protection.

No adjustment or maintenance is required. Much more compact than traditional tank systems, Mascontrol is absolutely dependable, durable and simple to install.

Over four million units currently in use world-wide.
