Pulp and Paper

Mill-wide pumping systems for stock, abrasive-corrosive streams, water supply, effluent, etc.

As one of the world’s largest users of water, pulp and chemicals, the pulp and paper industry requires pumps of virtually every type and size. Pulping and repulping services are extremely abrasive, with slurries up to 70% solids content. Paper stock preparation and chemical recovery are both highly corrosive and abrasive. Paper manufacturing pumps must be versatile, durable and, most important, reliable. Raw water supply, paper machine, power generation and effluent treatment are key applications.

Flowserve can provide complete mill-wide pumping systems, from paper stock service to chemical processing and water resources to power and steam generation.
