German pump producer LEWA has expanded the take a look at vary of its specially developed container check bench to take care of scorching or explosive fluids.
The test bench was initially launched in December 2018 but Lewa has thus far solely used water as the conveyed medium for testing and verifying pump capabilities. Many of the fluids Lewa deals with are ranked as supercritical by means of explosion hazard and employee safety, so the corporate has now expanded its take a look at range to cover most of these media.
In pressure gauge octa to an experimental area of explosion protection Zone 1 the place the check experiments happen, the container additionally features a secure control room with out explosion hazard for housing the drive and control tools. Supercritical fluids similar to gasoline, methanol, acetone or nitrocellulose thinner are used within the test chamber, whose interior can be considered via gas-tight glass panes, at process temperatures of as a lot as 80°C and a maximum amount of 200 l. A high-resolution information recording system ensures accurate monitoring and outcomes.
The preliminary take a look at has been carried out on the system to verify diaphragm clampings for micro-leakage utilizing a low-viscosity fluid and the the Lewa Ecoflow LDG3 kind with an M9 pump head.
