Tapflo Presents Aseptic Diaphragm Pump

Tapflo has launched the first in a series of aseptic diaphragm pumps. The series will be available in three sizes for sterile applications, primarily in the pharmaceuticals, biotechnology and food industries. The Tapflo pump series is certified by the European Hygienic Engineering Design Group (EHEDG). The first to be launched is the smallest, with a maximum flow of 94 litres/min.

In order for a pump to be EHEDG-certified, it must not feature any internal horizontal surfaces. The reason for this is to prevent any liquid from remaining in the pump after it stops. The pumps are supplied on a platform that allows them to be rotated; this enables the pumps to be emptied and cleaned simply, without dismantling. All surfaces in the pump have a high surface finish, making them easy to clean.

The pumps are also ATEX-certified for use with inflammable liquids, and pump components are approved by the Food and Drug Administration (FDA), US Pharmacopeia (USPVI) and DTI, the Danish Technological Institute. The Tapflo aseptic series is made up of a minimum number of components, making the pumps reliable and easy to maintain. The series is mainly constructed from components used in the company's other diaphragm pumps.

This is easier for customers and distributors because existing spare parts and accessories fit the new pump series, and do not require any extra storage space; nor is any special training needed for installing and using the pumps. No electricity is required; the pumps are powered by compressed air or any suitable propellant. Pump capacity is adjusted by altering the air pressure, which makes it easy to adjust to the manufacturing process. Few moving parts contribute to long working life and reduce risk of breakdown in the process.
