Digmesa Implements PEEK in Precision Flowmeter

Digmesa is implementing Victrex PEEK polymer in its latest precision flowmeter designed for demanding food processing applications.

Digmesa’s EPI flowmeter measures the fluid volume of highly viscous media such as syrup, oil or concentrated detergents. The EPI flowmeter is extremely precise and enables exact volume dosages over a wide temperature range with very low-pressure loss.

The areas of operation for the Victrex PEEK enhanced EPI flowmeters are extremely diverse and they must display excellent dimensional stability under mechanical and thermal load as well as a high level of resistance to wear-and-tear which may be caused by contact with the media being measured. Furthermore, in addition to a large flow at low pressure loss, excellent chemical resistance to the different media is also required.

Digmesa has implemented Victrex PEEK into the manufacture of the hollow bodies as well as in covers of the vanes and in the casing of its EPI flowmeter. Victrex PEEK150GL30, with its 30% flow glass reinforced grades, is used for the casing and the unfilled high viscosity Victrex PEEK 450G is used for the epicycloidal vanes within the flowmeter and in its hollow bodies. In this application Victrex PEEK is being substituted for metal and fluoropolymers such as ECTFE, PFA, PVDF providing Digmesa with cost-efficient production and considerable weight reduction of the device. Thermal insulation and low-temperature insulation are not required as Victrex PEEK is not thermally conductive.
