Peristaltic/Hose Pumps - Pulsatron/Pulsafeeder
Peristaltic pumps, also known as hose pumps, are positive displacement pumps that use a rotating squeezing motion to move fluids through a hose or tube. Peristaltic pumps are often used in applications where other types of pumps would be unable to function, such as when pumping viscous or shear-sensitive fluids. With a wide variety of peristaltic pump models, we have the perfect pump for your specific application. Centro carries a complete online selection of peristaltic pumps, including Peristaltic Chemical Metering Pumps, specially designed for corrosive or abrasive chemicals. Shop our selection of peristaltic pumps online today.

- A peristaltic pump, also called a hose pump or tube pump, moves fluid by compressing and releasing a flexible hose. Rollers or shoes rotate to push the liquid forward, making the pump ideal for thick, abrasive, or shear sensitive fluids.
- They can pump viscous fluids, slurries, pastes, abrasive mixtures, gases entrained in fluids, and chemically aggressive liquids. Since only the hose contacts the fluid, compatibility is easy to manage.
- Peristaltic pumps are used in chemical dosing, wastewater treatment, mining slurry transfer, food and beverage processing, paint and coatings, pharmaceuticals, and any application requiring gentle or precise flow control.
- Key advantages include accurate dosing, gentle fluid handling, excellent solids and slurry performance, no valves or seals, easy maintenance, and strong suction lift capability.
- Hose selection depends on chemical compatibility, abrasion, temperature, and pressure. Common materials include EPDM, NR, NBR, Hypalon, and reinforced rubber. Choosing the right hose is essential for pump life and performance.
