DEMA MixRite Water Driven Injectors are water-powered proportioning pumps that need no electricity that accurately dispenses at different water pressure and water flows. Ideal for in-line injection. Available in several types of models with a wide variety of injection rates and different materials to withstand many types of aggressive acids, alkaline, and solvents. The 500 series is available as a CW model with seals and components for mildly aggressive additives, 1400 models for corrosive material, acid, alkaline, solvent, and a PVDF model for the most aggressive additives.

Ultra Lean Metering Kit
-
- The DEMA #57.11.1 metering tip kit achieved leaner dilutions from 750:1 to 2000:1. This kit includes four different sized metering tips, 8’ (2.4m) of 1/4” vinyl tubing and a 3/8” barb adapter. Kit designed to work with 570/571 units.

Strainer
-
- The DEMA #50.41.1 3/4” NPT strainer is an in-line 200 mesh (80 microns) strainer recommended for all MixRite installations. The in-line strainer will keep debris out of the MixRite unit, increasing the life of the seals.
3/4” Anti-Siphon Kit
-
- For any 3/4” MixRites in-line to relieve pressure so chemical will not siphon out of drum or tank. DEMA #36073008002
Pressure Regulator & Gauge
-
- Fits in line with any MixRite to limit pressure spikes. DEMA #38030200001 for pressure regulator and 93.15.1 for gauge.
3/4” Check Valve
-
- DEMA #57.20.8, 3/4” check valve helps limit backflow situations if the unit is used to pump the mixture any significant distance.
UFR – Low Flow Booster
-
- The 57.UFR low flow booster works with any 500 series MixRite to take low flows (less than .9gpm) and allows the unit to work in low flow conditions.
Water Supply Hoses
-
- DEMA manufacturers a variety of water inlet hoses for different applications. DEMA inlet hoses are rated to 200psi, made of durable double-walled rubber, and crimped to our manufacturing facility specifications. Refer to the DEMA water supply hose guide included in the Resources section of this product page for more information.
