German pump manufacturer LEWA has expanded the test vary of its specifically developed container check bench to deal with hot or explosive fluids.
The test bench was initially launched in December 2018 however Lewa has up to now solely used water as the conveyed medium for testing and verifying pump functions. หลักการทํางานของpressuregauge of the fluids Lewa deals with are ranked as supercritical by way of explosion hazard and employee safety, so the company has now expanded its check range to cowl these varieties of media.
In addition to an experimental area of explosion protection Zone 1 the place the take a look at experiments happen, the container also includes a protected management room without explosion hazard for housing the drive and control tools.

A high-resolution information recording system ensures correct monitoring and results.
The initial test has been carried out on the system to check diaphragm clampings for micro-leakage utilizing a low-viscosity fluid and the the Lewa Ecoflow LDG3 sort with an M9 pump head.
