The inherent features and benefits of peristaltic pump
are well known and are supported through years of trouble-free operation in a variety of applications across multiple industries. Let's review these features as they apply to fill and dosing applications where cleanliness and accuracy are critical.
Accuracy and variable flow are the key requirements of the filling equipment. Accuracy protects investments in costly intermediates and end products; variable flow provides flexibility in handling a variety of containers, fluid viscosity, and process capability.
Accuracy and versatility of peristaltic pump
Maintaining dosing accuracy with high repeatability and minimal downtime often presents significant challenges for liquid fillers, especially when relying on a feed from centrifugal pumps or rotary vane pumps. It is often difficult to pump consistent repeatable flow rates with a rotary vane pump, and as with a centrifugal pump, disassembly, cleaning, reassembly, and disinfection are time-consuming. However, peristaltic pump
provides aseptic, liquid volumetric filling with accuracy of±0.5% or better, variable speed drive from 1 to 650 rpm, dispensing from 10 microliters to 10,000 liters. Variable speed drives coupled with many peristaltic pump heads can accept a range of pipe sizes, which allows the operator to perform height control over a wide flow range. The proven peristaltic design is also ideal for handling a wide range of fluid viscosities and is particularly gentle on shear-sensitive products (e.g. cell cultures and bioreactors).
