From mining tailings to chemical slurries, handling aggressive media demands more from pumping systems.
Peristaltic pumps (i.e. hose pumps) are stepping up with simplified maintenance, consistent flow control, and the ability to manage high solids content, making them a dependable choice for the toughest industrial environments.
Reliability in aggressive media and critical uptime
In process industries where uptime is critical and media are increasingly aggressive, the pump is evolving into a strategic asset. From abrasive mining slurries to corrosive chemical feeds, the demands placed on pumping systems are intensifying. In response, peristaltic pumps – also known as hose pumps – are gaining ground as low-maintenance, efficient, and reliable alternatives across sectors like mining, chemical processing, and water treatment.
A key innovation driving the adoption of peristaltic pumps is the single-roller design. Traditional shoe-based designs compress the hose twice per revolution, generating heat and accelerating wear. In contrast, single roller designs compress the hose once per revolution, reducing friction and extending hose life.
This design enables higher flow rates at lower RPMs, minimising energy consumption and wear.
For example, a 100 mm (4”) Valmet Flowrox hose pump can deliver 100m3/h (440 GPM) at 10 bar (150 psi), outperforming larger shoe-based pumps while maintaining a compact footprint and simplified maintenance. The pump is designed for continuous 24/7 operation, ensuring reliable performance even in demanding applications.
Effortless upkeep, reliable performance
Pump reliability goes beyond design – it’s defined by how easily the pump can be maintained. Peristaltic pumps feature straightforward service routines, typically requiring only a hose change every six months.
Under normal operating conditions, other components remain untouched. This high maintainability enables in-house teams to manage upkeep efficiently, minimising downtime and reducing dependence on external service providers.
As industries pursue sustainability and cost-efficiency, hose pumps offer tangible benefits:
- Reduced water usage thanks to the ability to pump higher concentrations of solids.
- Lower energy consumption and no overheating due to the roller design.
- Minimised downtime with simplified maintenance.
- Self-priming and dry-running capability, allowing stress-free, reliable startup.
- Improved process control via repeatable, exact flow per revolution, ensuring consistent and accurate dosing.
These advantages contribute to lower total cost of ownership and greater operational flexibility, making hose pumps a strategic choice for various industries.
Handling harsh media across industries
From abrasive slurries to corrosive chemicals, peristaltic pumps offer seal-less operation, high solids handling, and exceptional durability. In mining, they manage thick slurries without dilution. In chemical processing, they deliver accurate, repeatable flow – even with corrosive or shear-sensitive media.
Peristaltic pumps are no longer niche solutions; they’re strategic enablers of reliability, efficiency, and sustainability. Whether in mining, chemical processing, or water treatment, these pumps are helping industries meet performance targets while navigating increasingly complex operational challenges.
As process industries evolve, the role of the pump is being redefined, not just as a mechanical component, but as a driver of smarter, more resilient operations.
