An improved vacuum pump has a longer service life, and more

The new two-stage DuoLine rotary-vane vacuum pumps feature a newly developed pump system with optimized cooling. These changes have a significant impact on the pump’s service life, says the manufacturer. The long maintenance intervals, the energy-efficient motors and the optional…

These motorized valves consume less power

A new range of compact, lightweight motorized valves has been introduced for applications where electric actuation is required. The valves are quiet in use, and can be operated by a 24-V d.c. power supply, or by voltages between 24–48 and…

A new controller lets you empty drums automatically

The ViscoFlux mobile drum-emptying system has been further developed and now has an optional control unit enabling integration into a range of filling processes. For example, an end position cutoff can be integrated into the ViscoFlex so that the pumping…

Polymer-based Piping

Polymer-based piping systems offer a number of advantages, along with some limitations, compared to metallic and other non-polymeric pipe materials. The use of thermoplastic piping in the chemical process industries (CPI) must be carefully considered on a case-by-case basis because…

AODD pumps now feature a conductive PTFE diaphragm

This company’s E-Series Plastic AODD (air-operated double-diaphragm) pumps have been upgraded with electrically conductive polytetrafluoroethylene (PTFE) diaphragms (photo) to provide safer transfer of chemicals while avoiding electrostatic discharge. As a result, E-Series pumps equipped with conductive PTFE diaphragms can be…

This CO2 compressor is the biggest ever

Launched in May, the new semi-hermetic, six-cylinder GEA Block piston compressor HG46 CO2 T has a displacement of 21.8 to 30.3 m3/h. It is said to be the biggest semi-hermetic compressor for transcritical CO2 applications with operating pressures of up…

This modular piping system is approved for handling foodstuffs

The new Food Grade range of pipework systems is said to be the first product range on the market that meets the stringent requirements of the European standard EC 1935/2004, as well as the U.S. Food and Drug Admin. (FDA)…
