LEWA expands test range of container test bench

German pump producer LEWA has expanded the test range of its specifically developed container test bench to deal with hot or explosive fluids.
diaphragm seal take a look at bench was initially launched in December 2018 however Lewa has so far only used water as the conveyed medium for testing and verifying pump features. Many of the fluids Lewa deals with are ranked as supercritical when it comes to explosion hazard and worker safety, so the company has now expanded its take a look at range to cowl these kind of media.
In ไดอะแฟรม ซีล to an experimental space of explosion safety Zone 1 the place the test experiments take place, the container also includes a secure control room without explosion hazard for housing the drive and control gear. Supercritical fluids corresponding to gasoline, methanol, acetone or nitrocellulose thinner are used in the check chamber, whose interior can be considered by way of gas-tight glass panes, at course of temperatures of as much as 80°C and a maximum quantity of 200 l. A high-resolution information recording system ensures accurate monitoring and outcomes.
The initial test has been carried out on the system to verify diaphragm clampings for micro-leakage using a low-viscosity fluid and the the Lewa Ecoflow LDG3 kind with an M9 pump head.
