Fristam Pumps USA has developed a new, modified FKL A pump. We’ve taken the toughest, most durable sanitary positive displacement pump and optimized it for those who need to strip clean their pumps daily or between batches. The FKL COP features simplified O-ring sealing with shaft sleeves. And it’s still rated for 500 PSI. The FKL COP is currently available in models 25-400.A promotional video featuring the development of the FKL COP pump is online. See it here at www.fristam.com/cop.
