Hydro Systems Water Powered Dosing Pumps

Hydro Systems water powered dosing pumps are proportional chemical injectors that use the existing water flow and pressure as their power source. They inject a controlled amount of liquid concentrate into the water supply without requiring electricity.

Water flowing through the pump drives its internal motor or piston, which draws concentrate from a chemical solution container and injects it into the water stream. The amount of concentrate injected is proportional to the volume of water passing through the pump.

No. Hydro Systems water-driven pumps operate using the pressure and flow of the water supply, eliminating the need for an electrical power source.

The suitable chemicals depend on the specific pump, seal material and application. Hydro Systems offers different seal options to provide compatibility with a range of chemistries. For aggressive chemicals, Hydro Systems recommends its SuperDos HAC range, which is specifically designed for highly aggressive fluids.

Chemilizer uses diaphragm technology and is particularly suited to low-flow and hard-water applications. MiniDos is a compact low- to mid-flow injector with a broad range of injection ratios. SuperDos is designed for higher-flow applications and is available in models handling up to 45 GPM (10,000 L/h).

The maximum flow rate depends on the model. Chemilizer handles up to 2,500 L/h, MiniDos up to 2,725 L/h, while SuperDos models range up to 10,000 L/h on the SuperDos 45.

Dosing ratios vary by product and model. Chemilizer can dose from 0.6% to 5.0% on its adjustable models, MiniDos offers approximately 0.025% to 20%, and SuperDos models offer ratios ranging from 0.025% to 5%, with the SuperDos 20 also available in a 10% configuration.

Yes. The pumps are designed to inject concentrate in proportion to water flow. This allows the chemical concentration to remain consistent when the water flow changes within the pump's specified operating range.

Yes. Chemilizer is specifically designed for low-flow applications, with models operating from as little as 5 L/h. MiniDos is also designed for low- to mid-flow applications. The correct model should be selected according to the required flow range and operating pressure.

Yes. Hydro Systems identifies Chemilizer as a preferred water-driven pump for hard-water applications. Its diaphragm technology is designed to handle low-flow and tougher water sources, including pond and well water.

Applications include nutrient delivery, chemical delivery, line cleaning, animal health, horticulture, cutting-fluid dilution, coolant dilution, lubricant dilution and filling totes or drums, depending on the pump model.

Yes. Hydro Systems water-driven pumps are used in horticultural applications, including nutrient delivery and other chemical dosing applications. The appropriate pump should be selected based on flow rate, dosing ratio, chemical compatibility and operating pressure.

Yes. Chemilizer and SuperDos pumps are used in animal health applications. SuperDos is also designed for higher-flow applications, making it suitable for larger water systems where proportional chemical injection is required.

Yes, on models equipped with an on/off switch or lever. This allows chemical mixing to be stopped while water continues to pass through the pump, so the unit does not necessarily need to be removed from the water line.

Yes. Hydro Systems offers different seal options on its water-driven pump ranges to improve compatibility with different chemicals. Seal availability varies by product and model.

For highly aggressive chemicals, Hydro Systems recommends the SuperDos HAC range. These models use chemical-resistant materials and a design that helps isolate aggressive chemicals from the motor components.

The SuperDos 45 is the highest-flow model in the SuperDos range. It can handle water flow rates up to 45 GPM, equivalent to approximately 10,000 L/h.

A fixed-ratio pump is designed to inject at a specified dosing ratio, while an adjustable model allows the injection ratio to be changed within its specified range. Chemilizer is available with adjustable lower ends, while standard SuperDos models use fixed lower ends.

Select a pump based on the required water flow range, operating pressure, desired dosing ratio, chemical compatibility and application. The Chemilizer is suited to low-flow and hard-water applications, MiniDos covers low- to mid-flow applications, and SuperDos provides higher-flow options up to 10,000 L/h.

Yes. Like other mechanical dosing equipment, Hydro Systems water-driven pumps require maintenance and replacement of wear components as needed. Hydro Systems provides model-specific maintenance kits and documentation for its pump ranges. The required maintenance depends on the model and intensity of use.
