Description and Overview 

The D14MZ2VFBPII is the D14MZ2VFII with the by-pass option.

This DOSATRON is fitted at the top with a functional by-pass, allowing the user to choose when the Dosatron is activated or not:

  • By-pass ON, DOSATRON works and the concentrate is drawn up.
  • By-pass OFF, DOSATRON is stopped and does not draw up the product.

The D14MZ2 is the upgraded replacement for the 11 GPM model, allowing flow rates up to 14 GPM. It offers enhanced UV resistance and is perfect for one-hose operations or for use with our 15-gallon DosaCart or 5-gallon Li'l Bud-D portable fertilizing system.

Dosatron units feature superior engineering to create the most durable, easy-to-use, low-maintenance product on the market. We manage your chemical application through repeatability, regardless of fluctuations in pressure or flow. Dosatron also supports you every step of the way with world-class customer service. Trust only genuine Dosatron products.

How Dosatron Injectors Work:
The Dosatron pulls up solution like a syringe, drawing in the concentrate with the plunger. On the down stroke, the concentrate is displaced into the body of the Dosatron, where it mixes with the incoming water. Then just the right amount of fertilizer is discharged into the water line.
