Indian Paper industries have made good progress in last 2 decades. And they poised for further growth with advanced technologies. In order to have good and contiguous quality paper output there is need for chemical dosing system. We provide Chemical Dosing pump in pulp and paper industries in below applications,

1) PAC - Poly aluminium chloride …Piston type Dosing pump , PP piston - 500 - 700 lph

2) ALUM ..  piston type Dosing pump SS 304  piston …. 700 – 1000 lph.

3) Rosin  …Abietic Acid…piston type Dosing pump SS 304 piston …700 – 1000 lph

4) Parcol …. Piston type Dosing pump … 700 – 1000 lph Dosing pump.

5) Other application used Dosing pump ETP, RO plant, sea water plant, etc,

 Metering Dosing pumps can be considered a substitute to positive displacement pumps. Both pumps discharge a known volume with every revolution or cycle. The discharge volume is largely independent of back pressure. Metering pumps are much more accurate then positive displacement pumps. Metering pumps have an average accuracy of ± 1.0 percent.

 Diaphragm Pumps

Diaphragm pumps pulse a flexible diaphragm to displace liquid with each stroke. The diaphragm typically acts against a rigid plate. Its motion is analogous to a two-stroke engine. Diaphragm pumps deliver fluid with a high degree of pulsation. Diaphragm pumps can be solenoid operated or mechanical geared drive motor or hydraulically motor driven. Diaphragm pumps are used extensively for water treatment applications.

Solenoid pumps are the simplest, because they have the fewest moving parts. Timing circuitry energizes an electromagnet, which slides the diaphragm into the discharge position. The magnet moves against both back pressure and a spring. When the magnet is de-energized, it drives the diaphragm mechanism backward into the suction position. A system of check valves keeps the fluid flowing in one direction.Solenoids can pump against a dead head (infinite backpressure) because they are designed so that the electromagnet cannot force the diaphragm to move against a back pressure that exceeds its burst pressure. Magnets can be built in smaller size which is a practical limit to flow and pressures regimes for these pumps. They can typically pump up to 20 gph at 30 psi.

Mechanical diaphragm pumps have diaphragms that move in response like internal combustion engines. While they can deliver much higher flows and pressures, they should never be pumped against a dead head for fear of rupture of diaphragm.

Hydraulic diaphragm pumps are capable of higher flow rates and pressures than solenoid and mechanical units because they deliver the drive power force uniformly to the diaphragm. However, due to the complexity of valve and hydraulic subsystems, these pumps are expensive.

Mechanical and hydraulic diaphragm pumps are used in water treatment applications where the pressures are high.

Piston Pumps

Piston pumps act similarly to diaphragm pumps in that they mimic two-cycle engines. These pumps use a reciprocating plunger to move liquid through the unit. They have a rigid piston assembly, which gives them the highest pressure and accuracy of metering pumps. Since the piston slides against a cylinder wall, they should generally not run dry. Piston pumps can produce up to 5,000 psi and are ideal for high-pressure liquid chromatography applications. They are generally used in chemical processing, laboratory dispensing and water treatment applications.

The most common applications for metering pumps include water treatment, chemical processing and laboratory dispensing. Factors—such as chemical compatibility, media viscosity, temperature, flow rates and pressure—determine which metering pump best fits a specific application.

  Water TreatmentWater quality is one of the most challenging problems we face today. Approximately 1 percent of our water supply is fresh, and only a fraction of it is potable. Metering pumps are used for feeding chemical additives into the water. The types of additives being used—scale inhibitors, redox agents and non-oxidizing biocides—determine which pump category to select.Water soluble polymers settle out particulate matter “activated” in a water system. “Neat” (undiluted) polymer generally has a very high viscosity. Polymer is generally shipped in this form. Because of the low flow and pressure requirements, solenoid pumps are typically used for polymer feeds.Scale inhibitors such as zinc chloride prevent build up inside pipe walls, which constrict water flow, thereby reducing system efficiency.Acid/base agents such as HCl, H2SO4, NaOH and KOH control the pH of water. Most U.S. jurisdictions require discharged effluent to be within 5 and 7. pH also greatly affects the “kill power” of redox agents against biological contaminants.Redox agents such as NaOCl are used for biological control. They act by attacking an organism’s cell.Non-oxidizing biocides are used to control more vexing biological contaminates such as zebra mussels. Generally, they rely on toxicity rather than the ability to strip electrons to kill. Scale

inhibition, acid/base, oxidant/redundant and biocide treatments can use the whole range of metering pump technologies. The technology selection is driven by cost, material considerations, flow and pressure requirements.

  Chemical ProcessingChemical processing applications involve regulating feed rates. Reactant feed applications require releasing chemicals in real-time into reaction vessels, typically for manufacture or chemical synthesis. End-product processing uses metering pumps to accurately dispense product into a mold or container. The chemicals involved can include virtually any chemical precursor or end product.

Our pumps are used for all the applications described above.
