Dosatron Mini Seal Kit for D14MZ2, 14 GPM

Annual Mini Maintenance Seal Kit for Dosatron D14MZ2 14 GPM – PJDI116MINI-H

The Dosatron PJDI116MINI-H is the annual mini maintenance seal kit for Dosatron D14MZ2 series 14 GPM dosers. The D14MZ2 series operates in the 1:500 to 1:50 dilution range (0.2% to 2%) and uses a different internal seal configuration than the D14MZ3000 series — making the PJDI116MINI-H and PJDI139MINI-H seal kits non-interchangeable. Confirm the Dosatron model (D14MZ2 vs. D14MZ3000) before ordering the maintenance kit.

Like the D14MZ3000 seal kit, the PJDI116MINI-H includes the internal seal components along with accessories subject to routine wear: suction hose, bypass, union, weighted strainer, and quick start guide. Dosatron recommends annual seal replacement to maintain accurate proportioning and to proactively prevent leaks and dosing drift before they occur during the production season.

Who Should Use This Kit

The PJDI116MINI-H is for operators of Dosatron D14MZ2 14 GPM injectors on a preventive maintenance schedule. Because the D14MZ2 handles higher-concentration solutions (up to 2%), the internal seals may experience a different rate of chemical exposure compared to lower-concentration models — annual replacement ensures ongoing accuracy.

D14MZ2 vs. D14MZ3000 Series: Which Seal Kit Is Correct?

The Dosatron D14MZ2 (1:500 to 1:50) and D14MZ3000 (1:3000 to 1:333) series are similar in external appearance but use different internal piston and seal dimensions to achieve their respective dilution ranges. As a result, the maintenance seal kits are model-specific. The PJDI116MINI-H is for the D14MZ2 series. The PJDI139MINI-H is for the D14MZ3000 series. Installing the wrong seal kit will result in incorrect seal dimensions, leading to dosing inaccuracy or leaks. Locate the model number on the injector body or the original packaging before ordering.
