As production processes continue to evolve, peristaltic hose pumps are likely to remain at the forefront of innovation, helping industries excel in their production endeavors.
The operators in some of the world’s most demanding industries – from oil-and-gas production to mining and water/wastewater management to chemical processing – have come to rely on peristaltic pump hose technology when handling thin to viscous, particle-laden, aggressive, abrasive and corrosive liquids in potentially explosive atmospheres is required. In other words, peristaltic pump hose can successfully pump just about anything.
The design and operation of peristaltic pump hose technology, which was patented in 1925 in France, satisfy the requirements of such a wide range of industrial liquid-handling applications because the pump’s operation relies on the alternating contraction and relaxation of the hose, which force the contents to move through the pump and into the discharge hose.
A smooth-wall, flexible hose is fitted in the pump casing and is squeezed between shoes on the rotor that is positioned inside the pump casing. This rotating action moves the product through the hose at a constant rate of displacement. The hose restitution after the squeeze also produces a strong vacuum effect that draws product into the hose from the intake piping. The vacuum that is created by the hose’s restitution can build discharge pressures of as much as 16 bar (232 psi) without damaging or deforming the hose, or causing it to rupture.
This style also maintains excellent volumetric consistency, making it ideal for the strict dosing and 24/7 operating cycles that can be required in many industrial applications while typically providing suction-lift capabilities of as much as 9 meters (29.5 feet). Peristaltic (hose) pumps are also easy to operate and easy to maintain with no seats, valves, glands or mechanical seals needed, which leaves the hose as the pump’s only replacement part.
