MiniDos Water-Driven Pump

MiniDos low-mid-flow water-driven pump offers an ideal alternative to traditional, non-electric pump technology. Dilution range (4000:1 (0.025%) to 5:1 (20%)), up to 12 GPM (2725 L/hr.)

Non-Electric, Fluid Driven Proportional Injectors

The MiniDos low-mid-flow water-driven pump offers an ideal alternative to traditional, non-electric pump technology. MiniDos units are compact and offer a wide range of injection ratios. MiniDos is ideal for a wide variety of industrial and horticulture applications since it features a wide variety of different seal options that make it compatiable with a wide variety of different chemistries.

MiniDos operates without electricity to precisely inject liquid concentrates into a water supply line using fluid flow as the power source. It is designed with a patented internal mixing chamber that promotes homogeneous mixing, while segregating harsh chemicals from critical internal components. MiniDos comes in various models that easily satisfy the demands of your most challenging applications.

Discover the MiniDos Difference

  • Proprietary composite body which exceeds PVDF for chemical compatibility and for mixing aggressive chemicals
  • Built-in on/off switch which allows user to stop the injection, but not the system
  • Separate internal mixing chamber helps prevent chemical contact with motor piston, for longer life and uniform mixing
  • Highest standard operating pressure in the industry, minimizing pressure surge damage
  • Consistent and precise dosing even with fluctuations in pressure or water flow
  • Resistance to aggressive chemicals thanks to the specific design of the mixing chamber separated from the motor
  • Robustness of the pump body reinforced with glass fibers
  • Mixture quality
  • Interchangeable dosing lower parts
  • Maintenance or repair operations on the pumping system are simple, simple and practical

MiniDos Applications

  • Dosage or dilution of soluble lubricants: dosage of cutting oils, coolant, lubricants, additives, biocides, etc.
  • Agri-food: dosage of detergents, disinfectants, additives, etc.
  • Irrigation: liquid or soluble fertilizers...
  • Chlorination, Cleaning, Cutting Fluids, Degreasing, Disinfecting, Fertigation, Medication, PH/TH Correction, Pesticides, Soaps & Foams, Weed Control

Basic Installation

Operating Principle

Installed directly in the water supply line, the injector operates without electricity, using pressure as the power source. The water drives the injector, which pulls the required percentage of concentrate directly from the chemical solution container. Inside the patented mixing chamber, the concentrate is mixed with the water, and the water pressure forces the mixed solution downstream. The amount of concentrate will be directly proportional to the volume of water entering the injector, regardless of variations in flow or pressure.
