A metering pump moves a precise volume of liquid in a specified time period providing an accurate volumetric flow rate. Delivery of fluids in precise adjustable flow rates is sometimes called metering.

What does a doser pump do?

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.

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 is electronic dosing pump?

Electronic Dosing Pumps are known for providing an accurate flow rate and precise dosing. ... Pumps suck in a defined fluid volume with the backstroke of the displacer and press it into the dosing line with the pressure stroke.

How many types of dosing pumps are there?

Metering/dosing pump technologies fall into three categories: piston/plunger, mechanical diaphragm and hydraulic diaphragm.

What are peristaltic pumps used for?

Peristaltic pumps are a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained within a flexible hose or tube fitted inside the pump casing.

What does doser mean?

verb (tr) to administer a dose or doses to (someone) med to give (a therapeutic drug or agent) in appropriate quantities. (often foll by up) to give (someone, esp oneself) drugs, medicine, etc, esp in large quantities.

Where should a dosing pump be placed?

Put the pump in its permanent location near your tank – within a few feet is ideal. In order to prevent a siphon, be sure the end of the outlet tubing is higher than the top of the dosing containers or solution bottles. It is recommended that your solution be added to a high flow area of the sump after the equipment.

How does a dosing pump work?

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.

What is dosing in water?

Dosing involves tuning the levels of chemicals included to a batch or process stream to maintain a set concentration. This is accomplished by constantly monitoring the process using on-line instrumentation that automatically controls chemical dosing to guarantee levels are maintained without over- or under-dosing.

What is a dosing pump aquarium?

Dosing pumps are one of the primary types of aquarium automation devices. They're designed to automatically add precise amounts of additives to the aquarium water. The idea is to consistently add just the right amount every day to ensure a stable aquatic environment.

How do I start my dosing pump?

Which pump is used in RO plant?

There are 2 basic types of pumps used in RO systems - centrifugal pumps and positive-displacement pumps. The piping configuration for both pump systems is shown in the Figure. For the centrifugal pump, a throttling valve on the discharge line controls the feed pressure to the RO system.

What types of pumps are used in water treatment plant?

What is a DEF dosing valve?

The dosing valve is controlled by the computer and delivers precise amounts of DEF fluid to the decomposition reactor. The DEF fluid injected by the dosing valve is atomized into a fine mist and converted into ammonia while in the decomposition reactor.

When would you use a peristaltic pump?

Peristaltic pumps are typically used to pump clean/sterile or highly reactive fluids without exposing those fluids to contamination from exposed pump components.

What motor are used in peristaltic pump?

Typical motor speeds for peristaltic pumps range between 0-400 revolutions per minute. Usually, DC and BLDC motors are used together with a gearbox to set speed depending on the flow need. Stepper motor speeds can be regulated by using an external controller board.

How efficient are peristaltic pumps?

Peristaltic pumps are suitable for dispensing, metering and general transfer applications. Typically, peristaltic tubing pumps offer flow rates as low as 0.0007 mL/min to 45 litres/min and are able to generate pressures up to 8.6 bar (125 psi).
