Energy-efficient pumping and gentle handling of sensitive process fluids

Alfa Laval SRU rotary lobe pumps are engineered to provide reliable performance, trouble-free operation and energy efficiency for demanding applications in the dairy, food, beverage, personal care and pharmaceutical industries. Particularly suited to duties that require contamination-free pumps to meet high standards of hygiene, low-shear and low- pulsation operation, the pumps handle both cleaning-in-place and sterilisation- in-place, and can be supplied with thorough documentation to support rigorous validation requirements. The SRU rotary lobe pumps are designed with features that maximise performance and minimise the risk of contamination.

Understanding of flow patterns ensures high efficiency fluid transfer with low pulsation, low shear and low noise characteristics. Alfa Laval employs computational fluid dynamics (CFD) to establish exact geometry for the rotors and rotor case. The SRU features a robust gearbox construction with heavy-duty shafts, torque locking assemblies and taper roller bearings throughout. The SRU rotary lobe pumps comply with EHEDG, 3-A, 3.1 and FDA hygienic standards and have ATEX approval for use in explosive environments. Alfa Laval – Sweden

Premium threaded and coupled connection for thermal wells TMK has launched a premium threaded and coupled connection targeted at thermal wells. The new connection, TMK UP Ultra TM GX, successfully completed the testing and evaluation requirements of TWCCEP / ISO PAS 12835 for 290°C application. The pipes used for qualification testing were supplied by Volzhsky Pipe Plant (VPP). Thermal well casing connection evaluation protocol (TWCCEP) requires extensive material testing, rigorous finite element analysis, galling resistance test and thermal cycle test, followed by limit strain and bending tests. The FEA, galling resistance test and thermal cycle tests were completed in-house at TMK’s R&D centre in Houston, Texas, USA. The limit strain and bending tests were completed at C-FER Technologies, Edmonton, Canada. The new connection is already being promoted and offered to customers in Canada for thermal applications.
