Loose lid with on/off function for Mixtron pumps MX075, MX150, MX250, and MX300.

The lid with on/off function is an accessory that allows you to temporarily stop the dosing of additives without removing the dosing unit from the hydraulic system. Using a dedicated switch, you can lock the suction piston and open two valves inside the dosing unit. This enables incoming water to flow through and exit the system without drawing in any additives.

This solution is particularly useful in applications where users need to switch between treated and untreated water without interrupting the system’s flow. A typical example is seasonal agricultural activities, such as fertilization or veterinary treatments, where the need for additive dosing varies throughout the year.

Equipping the dosing pump with this accessory is optional for the end user, but it provides clear added value for system operators who require operational flexibility.
