Finish Thompson’s UltraChem range is composed of leak-free and magnetically driven pumps. With a clever case design and carefully chosen materials, the UltraChem pumps promise maximum reliability even in the most extreme situations without risks of sudden leaks and failure. The UltraChem series prioritises maximising the time between routine services by incorporating materials with high resistance to corrosion caused by strong chemicals. Specifically, the series combines a tough ductile iron casing with a Tefzel (ETFE) lining for superior corrosion resistance.
