Why are dosing pumps used?
A metering pump (also called a dosing pump) is used to add small but accurate volumes of a liquid to other fluid streams or vessels. Metering is achieved by controlling the pump's speed or stroke length to achieve a specific delivery rate or by controlling the period of operation to supply an accurate single dose.

How does an air pump work?
The small compressor or air pump injects air into a treatment tank. The water being treated falls into the treatment tank where the compressed air oxidizes the iron and hydrogen sulfide, making them easily removable by the filter that follows. The air pump is quiet, dependable, and economical to operate.
How does an Aquatec permeate pump work?
It functions by storing the hydro power from the RO unit's drain water stream and using this energy to force product water (permeate) into the RO unit's storage tank. It frees the reverse osmosis unit from the need to contend with back pressure from the air-pressurized storage tank. The result is that the RO tank fills faster and the unit uses less drain water and produces better quality water.

The Stenner variable speed injection pump feeds liquids at a very slow rate but at high pressure into a water pipe. It is used for a variety of purposes. For example: 1 It feeds chlorine to kill bacteria or to oxidize iron or hydrogen sulfide. 2 It feeds soda ash to raise the pH of acidic water. 3 It feeds polyphosphate to “sequester” iron or hardness. 4 It feeds hydrogen peroxide to oxidize hydrogen sulfide or iron.
What is a Grundfos repressurization pump?
The sophisticated one HP Grundfos repressurization pump is actually in function a much larger version of the small demand pump. It delivers water on demand to homes and other large applications. The quiet, smooth operating pump has its own small built-in pressure tank to assure smooth, instant delivery of water upon demand. It functions without the added pressure tank that is normally used with well pumps.
What is the function of a RO booster pump?
The function of the RO booster pump is to increase the pressure of reverse osmosis feed water. Reverse osmosis is a pressure-driven treatment. Increasing the inlet pressure improves both the product/reject efficiency and the quality of the product water (TDS). Conventional residential RO units can run on as little as 40 psi, but they perform with much greater efficiency at 60 psi or above.

What is a dosing pump?
A dosing pump is a positive displacement pump designed to transport very precise flow rates of a chemical or other substance into a fluid stream. The mechanism of this industrial pump involves drawing a measured quantity of fluid into the chamber and then injecting this volume rate into the container being dosed. As a function, a dosing pump is designed to be reliable so once it is properly set up; it should look after itself and not require large amounts of input. Dosing pumps are used for automating fluid flow in many applications including pharmaceutical water treatment plants.
Can a peristaltic pump handle high pressure?
Peristaltic pumps are highly accurate. However, they wear out quickly; and can’t handle pumping into a high pressure stream as they can only handle up to the burst pressure of the flexible tube mentioned in the beginning. Applications of Dosing pump for water treatment plant. Dosing pumps are used widely across many industries.
How to inject water into a well?
Water injection in oil wells involves the following steps: 1 Injection wells are first drilled close to the producing well to be remediated. (An injection well is a well that is designed to channel water or other fluid into the surrounding formation in close proximity of a producing well to stimulate hydrocarbon production or for fluid disposal purposes). 2 Produced water or treated water is pumped into the formation under high pressure. Tests may be carried out to ensure that the produced water to be injected is compatible with the formation, therefore the water may be treated to remove fine particles that might clog the well and oxygen that encourages the growth of bacteria. 3 The pressurized fluid exerts a sweeping force that ‘mops up’ existing hydrocarbon from hard-to-reach areas in the formation, driving the products toward a nearby producing well for collection via a production casing.
What is an injection well?
Injection wells are first drilled close to the producing well to be remediated. (An injection well is a well that is designed to channel water or other fluid into the surrounding formation in close proximity of a producing well to stimulate hydrocarbon production or for fluid disposal purposes).

How to tell if well pump is 110V or 220V?
NOTE: When ordering a well water chemical feed pump BE SURE you know if it is 110v or 220v well pump that you have. The Chemical Injection Pump should be the same voltage as the well pump in most cases. Just look at the switch for the well pump on your breaker box. If it is a single breaker switch, you have a 110v well pump. If it is a DOUBLE switch, you have a 220v well pump. That means you want the same well water chemical feed pump, or chlorine feed pump. Chlorine production depends on chlorine and water mixture. We will be happy to advise you on the mixture for your application.
