Types of Pulp and Paper Stock Pumps
1. High-Pressure Pumps for Chip Board Manufacturing
The width of the web paper is determined by the former or wet-end section of the paper machine. To trim the edges a pair of trim squirt nozzles are used to focus on either side of the web a high-pressure jet of water. The knock off showers separate the cut edges from the rest of the web. The edges of the wire are forced back into the broke chest by the knock-off showers that are placed beneath. A mixture of material and pulp is formed and reused in the broke chest.
The width of the finished product is determined by Trim squirt application and it maintains the web integrity also. The wet pulp at such an early stage in the dynamic has not been through the dryer or press section. The web can get entirely ripped by the occurrence of interruption in the flow, or any irregularity or a flawed edge for that matter can stop the machine. It will eventually be re-threaded and cleaned which is very expensive and consumes a lot of time.
In the process of papermaking at various points, each kind of chemical is put to use. The abrasives are pumped with any damage if the pumps are seal-less in nature. There are available choices of materials that enable the paper and pulp pumps to handle truculent chemicals. The metering pumps with standardized diaphragm pulse several times which causes impairment or damage of the piping system.
Their uses are:
- 1. chlorine injection to the streams of wastewater,
- 2. pesticides into the white water,
- 3. injecting dyes and polymers in the headbox.
In some mills, a high impact fan nozzle is used to pass through the width of the fabric for the purpose of cleaning. The reciprocating nature of the nozzles makes usage of a fraction of water that is released through various branches of the piping system. Thus, it becomes important to use such pulp and paper stocks that provide a pulse-free flow. It is difficult to repair the turbine pumps of high speed and pick up tubes but it is comparatively easier to repair the types of pumps with the properties mentioned above. They provide more efficiency as well.
2. Centrifugal Process Pumps
The most popular used paper and pulp pumps are centrifugal pumps in the paper and pulp industry. They come under the type of back-pullout and end-suction centrifugal pump. The manufacturing of paper has been coupled with various processes. The wood pulp paper gets manufactured in this industry called the pulp paper industry. The deinked pump is produced by the waste paper which involves washing and dissolving of fibres.
The centrifugal pumps perform all the handling and transferring process of fluid. The corrosive materials contain a wide-spectrum which can be handled with the help of centrifugal process pumps. Pulp pumps is another name given to the centrifugal process pumps in the pulp and paper industry.
Specifications of a centrifugal pump as per your organization
The capacity of centrifugal process pumps is 1100m3 per hour, it can manage 15 kg per cm2 pressure and lies between 25mm to 300mm in size. The highest speed limit is 3500 revolutions per minute.
3. Slurry Pumps
The centrifugal force applied by centrifugal pumps increases the solid and liquid pressure and make slurry pumps the most efficient pump. There is a conversion of electrical energy into the kinetic and potential slurry energy.
Specifications of slurry pump as per your organization
The slurry of high concentration and corrosives are transported using slurry pumps in the pulp and paper industry widely. They lie in the range between 75mm to 300mm. They can produce 1035kPa pressure and are 73 m long.
The paper stock and pulp pump manufacturers have to keep various aspects in their mind related to the customers’ expectations with their products. Customers want to see the results and thus in this rapidly growing industry of pulp and paper in the past recent years, the pumps manufacturers have developed their work quality.

Provision free maintenance, wearing parts replacement in the field, two casings that help in replacing the worn-out front cover without changing the complete casing and highly efficient slurry pumps should be manufactured for the pulp and paper industry. Because of their wide use across the world, these salient features must be fulfilled and kept in mind while designing and assembling of the pulp and paper stock pumps.
The Ideal Pulp and Paper Stock Pump For Your Business
Pulp and paper stock pumps can work at a higher pressure in continuity with a little maintenance and are highly preferable for chipboard manufacturing. Low pulsation reduces the dampers requirement for pulp and paper stock pumps with a diaphragm. The pumps that do not need fine filtration and reduce expenses are the best option. The maintenance should be simplified to make them more efficient and least time-consuming.
The pumps should be resistant to corrosive materials and chemicals attack with an ability to handle small solids. The pump seals should be able to stand against the harmful liquids that are likely to damage them. The manufacturing process should thus enforce such material quality that produces seal-less diaphragm pump design with an ability to withstand all the hurdles.
