The range of vortex pumps of the series SEMA from the company Allweiler designed to work with aggressive, dangerous (toxic, explosive) and aerated (up to 50%) liquids, the installation kit includes a magnetic coupling for torque transmission that ensures complete tightness of the structure. Self-priming, the orientation of the outlet and inlet pipes depends on the version version (listed below). Single and multi-stage structure, practical modular design. Due to their technical features, they are not at all demanding in maintenance. Standard three-phase models with a closed design are used as electric motors.
Versions of the SEMA series execution
SEMA-S - with very low NPSH values, coaxial feed
SEMA-L - two upper nozzles, pressure on the drive side
SEMA-Z - two upper nozzles, suction on the drive side
SEMA- BLOCK - closed coupling connection, coaxial feed
Pumping liquids Distilled water, distillate, alkalis, acids, hydrocarbons, lubricants, chemical solutions of various nature, including those with gas impurities.
Limitations: no abrasive particles.
Areas of application: chemical industry, extraction, cooling, various technological processes, etc.
