Friday, December 19th, 2014 von admin

Wilden_Advanced-FIT_PS830-SSThe new Wilden air-operated double-diaphragm (AODD) pump series 430 and 830 Advanced FIT is produced of 316 stainless steel for higher corrosion resistance in aggressive chemical applications. These sieries have been specifically designed to be direct replacements for existing Wilden 38 mm (1-1/2”) and 51 mm (2”) Advanced pump installations.

“FIT” means

  • bolt-to-bolt and

Lewa: Hermetically tight 170 °C high-temperature pumps for production

Wednesday, December 17th, 2014 von admin

Wacker_freiIn the existing chemical installation in a Wacker Chemie plant, the safety-related design of the relevant pump systems had to be thoroughly renovated. One of the basic requirements for the redesign was that diaphragm pumps themselves had to remain absolutely hermetically tight, even at high working temperatures of +170 °C during normal operations and brief peaks as high as +200 °C. As a result, Lewa developed an individual solution to meet the specific customer requirements.

“As an additional security measure, the pressure-free hydraulic reservoir behind the diaphragm is blanketed with nitrogen as a protective gas”, explains Lewa project lead Rainer Sonnenfroh.
