There are many many different types of PUMPS manufactured around the globe. Obvious reason for this is the requirement of the end-user. But not all pumps are created equal, despite the fact that they may be labelled for certain uses.

Because diaphragm pumps are so versatile for fluid transfers they are used in vast industries such as: Pulp and Paper, Textile Industry, Agricultural, Food and Beverage, Pharmaceutical, Hospitality, Oil & Gas Industry, Hotels And Resorts, water treatment just to name a few. At its core, when dispensing and metering is required, metering pumps get the job done due to their efficiency and accuracy.

WRS diaphragm metering pumps are known for their safety as well as their cost-effectiveness in the facilities where they are utilized. Due to various additional components and their own innate mechanisms, metering pumps can gauge pressure, prevent fluid from flowing back, and prevent chemical corrosion, and that makes them one of the best choice in quality metering pumps.

Diaphragm pumps fall into a wide range of industrial applications.


Flocculation is a well-known purpose for metering pumps as well as coagulation, both of which are used to treat contaminated industrial water as well as used for wastewater treatment. These processes collect solid and semi-solid particles in one place so they can be removed manually or through industrial strainers. It is necessary for the process to be done with a high level of accuracy as this recycled fluids are re-used and in the case of water treatment where it often finds its way back to houses and factories.

It has to be free from sediment, waste, bacteria, and an array of other toxic particles. Depending on the quality and motor of the metering pump you are using, some wastewater treatment plants are able to pump out thick and larger polymers to do a more efficient job. The ball valve assemblies in the diaphragm metering pump keep the chemical pumping at a consistent rate according to the calculations done by the staff or on-site manager.

Balance That pH

pH balancing of water is also done with the help of chemical dosing metering pumps in which Sulphuric Acid is added with caustic soda to balance the PH in a collection of water. Sometimes this is a secondary or additional step in general wastewater treatment. Neutral pH is usually the most desired but certain industrial processes may require a specific level which can then be adjusted with the amount of the chemical that is being pumped.

Boiler Water

Boiler water treatment is an accompanying function or purpose that is carried out in certain industries. Typically an assortment of three chemicals is utilized such as Ammonia, Phosphate, and Oxygen scavengers. These chemicals as they are disseminated in the water help the boiler to operate better. The cleaner and more filtered the water is, the more steam can be produced.

Nothing But The Best

Buying the best diaphragm metering pumps is more than just about spending the right amount of money; it is also about having knowledge of fluids being metered, compatible ancillary components that can improve performance considerably.

Consider in detail your requirements, some processes are more concerned with flow rate than anything else while others may value convenience so remote control options may be more suited. Most metering pump manufacturers and suppliers have experts, sales reps as well as qualified staff that can help you make the right decision by introducing you to the pros and cons of each model of metering pumps, providing advice through the methods that suit you, or by arriving on-site and gauging your requirements.

Good to Knows

Flocculation: in colloid chemistry, flocculation refers to the process by which fine particulates are caused to clump together into a floc. The floc may then float to the top of the liquid (creaming), settle to the bottom of the liquid (sedimentation), or be readily filtered from the liquid.

pH: pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

Coagulation: the action or process of a liquid, especially blood, changing to a solid or semi-solid state.
