What is a chemical feed pump

A dosing pump, or often referred to as a metering pump, is a device used to accurately deliver a precise amount of liquid or substance under controlled conditions. While similar to generic dosing pumps, the chemical dosing pump differs in its type of application within specific industries and its usage in the process.

What is chemical feed pump?

A dosing pump, or often referred to as a metering pump, is a device used to accurately deliver a precise amount of liquid or substance under controlled conditions. While similar to generic dosing pumps, the chemical dosing pump differs in its type of application within specific industries and its usage in the process.

What does a chemical pump do?

A chemical feed pump, also known as a chemical dosing pump, is a compact positive displacement pump that injects a precise amount of chemical or other substance into water, gas, or steam.

What is a chemical feed system?

Chemical Feed Systems are designed for automated chemical injection into the chemical feed tank for wastewater treatment. In the dosing process, chemical reagents are added into a water stream at a precisely controlled rate with positive displacement metering pumps.

How do chemical dosing pumps work?

The pump draws a fixed volume of a chemical into the chamber, and then injects it into a pipe or a tank that may contain water or fluid to be dosed. The pump is driven by an air actuator or an electric motor.

What kind of chemical feeder is a peristaltic pump?

The category of positive displacement liquid solution feeders includes peristaltic pumps, diaphragm pumps and piston pumps. Peristaltic pumps move chemicals through a flexible feed tube, squeezing the tube with a rotating set of rollers and producing an output-side pressure that usually falls between 25 and 100 psi.

What is a chemical feed tank?

Wessels by-pass Chemical Feed tanks are designed for reliable induction of chemical treatment into a closed loop system. Typically used in hydronic and process piping systems. … Typically used in hydronic and process piping systems, SS-CPBF vessels support industry standard #1 or #2 filter bags (sold separately).

What type of pump is a dosing pump?

A dosing pump, which is a positive displacement pump, is designed to inject a chemical or another substance into a flow of water, gas, or steam. Dosing pumps, which are typically small, provide an extremely precise flow rate for maximum control.

How does a chlorine pump work?

Metering pumps are used to inject a small amount of chlorine (sodium hypochlorite solution, or calcium hypochlorite solution) into the water, usually in conjunction with a contact tank. The pumps draw chlorine bleach from a solution tank and pump it into a pipe under pressure.

What is chlorine injection?

This system dispels iron, bacteria, and hydrogen sulfide. To do this, a chemical feed pump injects chlorine into the incoming water on an on-demand basis. From there, the chlorine undergoes a chemical reaction (oxidation) with the iron, bacteria, and hydrogen sulfide in the water in a mixing tank.

How many types of pump are there?

There are three basic types of pumps: positive-displacement, centrifugal and axial-flow pumps.

Which pumps are used in industry?

Centrifugal Pumps. The best choice for lower viscosity liquids and high flow rates.
ANSI Process Pumps. …
API Process Pumps. …
Axial Flow Pumps. …
Booster Pumps. …
Piston Pumps. …
Progressive Cavity Pumps. …
Screw Pumps.

What is a chemical metering pump?

Water Treatment—pH Level Often, chemical metering pumps are metering sulfuric acid or caustic soda to help balance pH levels. Sulfuric acid helps reduce high alkalinity, and caustic helps neutralize acidic water. There are many other chemicals that can be used to balance pH, but these are two of the most common.

What is the purpose of dosing pump?

A dosing pump is a positive displacement pump that is designed to inject a chemical or any other substance into the flow of water, gas or steam. Dosing pumps are typically small and provide an extremely precise flow rate for maximum control.

Why are dosing pumps used?

Dosing pumps provide low volume, controllable discharge rates that are used to inject various chemicals, solutions of various viscosities. Dosing pumps are also called metering pumps because they pump accurate volumetric rates of fluids.

What is the purpose of dosing?

The word dosing is very commonly used by engineers in thermal power stations, in water treatment, in any industry where steam is being generated, and in building services for heating and cooling water treatment. Dosing procedures are also in vogue in textile and similar industries where chemical treatment is involved.

What are glycol feeders?

Neptune Glycol Feeders are designed for the addition of glycol solution to closed loop chilled or hot water systems. The system automatically maintains pressure in the loop by adding glycol solution to make up for losses which occur due to leakage.

What does a peristaltic pump do?

Peristaltic, tube or hose pump is a type of positive displacement pump that transports the liquid through the tube by a series of rollers, that squeeze it against the pump housing, in a similar way that we swallow food.

What is a chemical bypass feeder?

Bypass Feeders are used for introducing a predetermined volume of treatment chemicals into chilled water as in air conditioning systems or hot water treatment in heating systems or large engine water jackets. … Instead, water pressure circulates the chemical dose through the system.

What is peristaltic water pump?

A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing. … The part of the tube under compression is closed, forcing the fluid to move through the tube.

What is a peristaltic metering pump?

A peristaltic metering pump is a type of positive displacement pump. Fluid is pumped through a flexible tube in a peristaltic motion. … As the rotor turns, the rollers pinch the tubing to force the fluid through. When the tube is not compressed, the fluid flow is brought into the tube.

Are chlorinators safe?

Pathogens present in water can be transmitted through a drinking water distribution system, causing waterborne disease in those who consume it. … Along with other water treatment processes such as coagulation, sedimentation, and filtration, chlorination creates water that is safe for public consumption.

Can you make chlorine at home?

To mix chlorine bleach combine 5.25 percent sodium hypochlorite and 94.75 percent water. To mix non-chlorine bleach, combine equal parts hydrogen peroxide and water. Pour mixture into the plastic container, and secure tightly. Shake to mix ingredients.

How do you chlorinate water at home?

Add one heaping teaspoon (approximately ¼ ounce) of high-test granular calcium hypochlorite (HTH) to two gallons of water and stir until the particles have dissolved. The mixture will produce a chlorine solution of approximately 500 milligrams per liter.

Where are dosing pumps used?

Metering or dosing pumps are used extensively for controlled chemical addition to a process. They can be of almost any type depending on the metering accuracy required.

What chemical is used in chilled water?

Chiller chemicals are used to control corrosion and to prevent bacteria growth. The most common chiller corrosion chemical is a closed loop nitrite, borate, silicate product. The second chemical is a cooling water biocide.

What is diaphragm dosing pump?

The mechanical diaphragm dosing pumps use a fixed ratio mechanical gearbox which translates the rotation of the motor to the reciprocating action of the piston. By changing the ratio we can increase or decrease the number of strokes per minute that the piston dosing pump makes.
