NEW PUMP SERIES CONSERVES SPACE WHILE DOSING ACCURATELY

ALLWEILER HAS LAUNCHED THE next-generation of its AEB-DE progressing cavity pump series with four pump sizes that share one installation footprint and are capable of bidirectional flow.

Combining proven features from two dosing pump ranges with newly optimised rotor and stator geometries, the new range aims to deliver the utmost in accurate dosing of high viscosity and particulate-filled fluids.

In addition to simplifying pump selection and the quote process, the space-saving modular setup of the dosing pump series makes standardising simple without regard for required flow rates or fluid characteristics. Skid builders will simply outfit the installation space for the specified pump according to the operating data provided. This flexibility facilitates future variations in needed flow rates with simple changeouts of conveying elements. No cost-intensive refurbishments or adjustments to piping are necessary.

The AEB-DE’s new suction casing has three additional closed drillings that can be used for various functions. Customers can fill the pump, to drain it or to install additional auxiliaries if needed.

In addition, the new design of the casing ensures permanent flushing and cooling of the seal as it is located in the flow of liquid. This means the pump can also be installed vertically without any risk of seal failure. To further ensure safe plant operation and preventable breakdowns or damage to the pump, the AEB-DE series can be upgraded with smart dry running protection or a pressure sensor.

MAKING THE MEDICINES OF THE FUTURE

WATSON-MARLOW FLUID Technology Group (WMFTG) has introduced the ReNu SU cartridge assemblies with a 10-6 SAL to help satisfy a growing demand for sterile single-use pumping technology which is essential for the commercialisation of potentially life-changing personalised medicines.

The cartridge assemblies are for use with the company’s Quantum peristaltic pump and offer a closed system for making sterile connections in non-sterile environments.

The ReNu SU Technology cartridge assemblies can be integrated directly into a customised fluid path, allowing for quick bioprocess integration while eliminating alignment errors. This reduces cost and lead time by simplifying the supply process. The closed system comprises an irradiated cartridge sealed at each end with a choice of three different types of aseptic connector, providing a simple, flexible assembly that can easily be installed into existing systems. With guaranteed sterility assurance, customers can use ReNu cartridges without needing to take further steps for any additional cleaning or validation.

The ReNu SU Technology cartridges are said to be the heart of WMFTG’s Quantum pump, which offers high accuracy with flow linearity independent of back-pressure. This virtually pulse-free performance enables constant pressure, reducing possible damage to fragile media such as cells and allowing higher downstream process yields throughout the pressure range.
