Chip Board Manufacturing Pumps

Chip Board Manufacturing High Pressure Pumps from Hydracell

Pumps from Hydracell are ideal for manufacturing of chip boards due to their seal-less design, so there are no seals, packing or cups to leak or replace

Paper Pumps and Pulp Pumps

Trim Squirt

In the “wet end” or former section of a paper machine the width of the web of paper is determined. A pair of trim squirt nozzles are used to focus a high pressure jet of water on either side of the web to trim the edges. The cut edges are separated from the rest of the web with “knock-off showers” which are placed beneath and force the edges off the wire and back into the broke chest. In the broke chest, the material is mixed into pulp and reused.

The trim squirt application is critical because it determines the width of the finished product and helps maintain the integrity of the web. At this early stage in the process, the wet pulp hasn’t been through either the press section or dryer. Even a slight irregularity, interruption of flow or flawed edge can cause the entire web to rip, forcing the machine to be shut down, cleaned and re-threaded. This is time consuming and very costly.
The Hydra-Cell® paper pumps and pulp pumps provide a pulse free reliable flow to the trim squirt nozzles. The Hydra-Cell® paper pumps and pulp pumps are far more efficient than the centrifugal counterparts often used in the application. A 1/2 HP motor can provide the same required flow and pressure as a centrifugal needing as much as 5 HP. In a 24 hour/7 day a week operation, the savings are substantial. The ease of maintenance and low cost of parts offer other advantages.

Chip board manufacturing-pulp and paper


Some mills use a high impact fan nozzle that travels the width of the fabric for cleaning. Because the nozzle reciprocates, it uses a fraction of the water that conventional stationary manifolds use. The Hydra-Cell® paper pumps and pulp pumps are a perfect fit due to its reliability and pulse free-flow. The Hydra-Cell® paper pumps and pulp pumps are far more efficient and easy to repair than the pick-up tube or high speed turbine pumps that are often used.

Chemical injection

All sorts of chemicals are metered in various points in the paper making process. Hydra-Cell® paper pumps and pulp pumps can handle aggressive chemicals because of the choices of materials available and, being seal-less, will pump abrasives without damage. Conventional diaphragm metering pumps often pulse causing damage to the piping systems. Applications include: injecting chlorine into the waste water stream; biocides into the “white water”, polymer injection and dyes into the head box.

Hydra-Cell® Diaphragm Pump Advantages

The seal-less nature of the Hydra-Cell diaphragm pumps enable charged and dirty liquids to be processed without need for fine filtration to protect the diaphragm pump.

The Hydra-Cell diaphragm pump needs little maintenance and can operate at continuous duty at high pressure.

Pulsation is low, so dampeners may not be required for most Hydra-Cell® diaphragm pumps.

Hydra-Cell® diaphragm pumps can handle solids up to 500 microns, or more. They can be pumped without fine filtration. System costs are reduced and maintenance is simplified.

Most diaphragm pumps in the Hydra-Cell® diaphragm pump range can operate at any pressure from <1 bar up to at least 70 bar. Some models up to 170 bar.

Seal-less design distinguishes the Hydra-Cell® diaphragm pumps from other diaphragm pumps and is the basis of its long service life – many of the liquids pumped are harmful to pump seals. The Hydra-Cell® diaphragm pumps are tolerant of small solids, resistant to chemical and corrosive attack.
