Pump seal replacement ALLWEILER AG NTT 65-200U5AW4

High-temperature cantilever pump ALLWEILER NTT - for pumping thermal oil, self-cooling. Pumps are used in particularly harsh conditions: asphalt production, mineral wool production, oil industry - processing of dark oil products, bitumen production, heating of bitumen tanks, paint and varnish industry, food industry, production of plastics, tires, rubber, roofing, etc. Accordingly, the mechanical seal must be as durable and reliable as possible.

BTS seals fully meet these criteria, using Viton rubber (fluoroelastomer), solid carbon, antimony-impregnated / SSic, silicone carbide. Shaft seal U5A (item 433.02) - uncooled, maintenance free, unbalanced. In front of the mechanical seal there is a safety stuffing box with the next throttling zone. Even if the mechanical seal fails, these additional safety elements prevent fluid from leaking. It is guaranteed that any leakage heat escaping from the shaft seal is safely discharged through the LO leakage outlet and fully collected. Due to the special design of the integrated unit, the temperature is reduced to such an extent that proper functioning of the bearing and shaft seal is ensured.
