In duties ranging from paper coating and preparation to high pressure cleaning, wet-end trimming and extremely accurate metering (exceeding API 675 standards for metering pumps) the reliability of Hydra-Cell seal-less pumps is well-proven in the paper industries.
The pumps are handling recycled water, abrasive fluids, fluids with solids in suspension, chemicals, non-lubricants and many other difficult liquids. Many of the fluids used are abrasive and react with air to crystallise or harden, which can cause problems with pumps that have mechanical seals. Hydra-Cell’s seal-less pump design means that this is not a problem.
Hydra-Cell pumps are seal-less.
Many of the chemicals used in the paper and pulp industry are abrasive or react by crystallising or hardening when they come into contact with air. This can lead to problems with mechanical seals creating extra maintenance work. Hydra-Cell’s seal-less design gives large savings in maintenance.
Energy savings. Compact and highly efficient (85%), a Hydra-Cell pump can be fitted with a smaller motor than would be required by many pumps for the same flows and pressures. See table comparing examples of Hydra-Cell v centrifugal pumps.
Hydra-Cell pumps can handle solids up to 1mm, or more. They can be pumped without fine filtration. System costs are reduced and maintenance is simplified.
Most pumps in the Hydra-Cell range can operate at any pressure from
<1 bar up to at least 70 bar. Some models up to 170 bar.
The relationship between flow and pump speed is a straight line. Flow is easily controlled within ±1% accuracy simply by controlling pump speed – with turndown ratios of 10:1 or better.
Flow is steady, with little pulsation.
High pumping efficiency (85% compared for example with 45% for a typical centrifugal pump) is enabling mills to save energy, while also reducing maintenance and repair costs.
Electronic control of flow (via motor speed) makes automation simple and inexpensive. Very low pulsation, avoiding need for pulsation dampeners, reduces cost of many metering and chemical injection systems, and cuts wastage at web trimming stage.
