Bedaflow systems presents magnetic couplings. The technology involves use of permanent magnets to transmit motor torque to the pump without contact. This enables sealing of the pump shaft hermetically, thus preventing leakage of fluid medium from the pump seals. These coupling are used in providing solutions of leak proofing pumps and agitators handling hazardous and difficult to use chemicals. The various features of magnetic coupling includes prevention of harmful emissions, no wastage of chemicals, no downtime in changing seals, etc. The coupling finds applications in isocyanate and polyol pumps in polyurethane machines, pharma and chemical process industries, food applications, biotechnology, industrial ovens and batching machines, bottom mounted agitators for blenders and mixing vessels, etc.
