Compact and reliable mechanically realed pump

The CTP pumps are semi open single stage centrifugal pumps. Since there are no metal parts on the liquid side, the pumps are ideal for chemicals transfer and circulation in surface treatment industries.

CTP is a compact and reliable mechanically sealed centrifugal pump made in PP and PVDF. It is the right solution for liquids containing solid particles.
