Robust SAWA high-pressure centrifugal pumps are ideal for high system pressures and are used in reverse osmosis systems up to a nominal pressure of PN25 or PN160. The material used, 1.4435 /316 L, is also suitable for pumping highly concentrated solutions, alkalis and certain acids, which may also be corrosive. The robust design and the bolted housing construction guarantee the user the highest operational safety at system pressures of up to 160 bar, which are often generated with piston pumps. Especially suitable mechanical seals are installed in SAWA high-pressure centrifugal pumps. If absolute safety with regard to environmentally hazardous liquids must be guaranteed, the high-pressure centrifugal pumps
are designed with a magnetic coupling and are therefore hermetically sealed and also approved for ATEX applications. The simple design of SAWA high-pressure centrifugal pumps guarantees rapid replacement of the mechanical seal and consequently short maintenance times. Thanks to their hygienic design, SAWA high-pressure centrifugal pumps can be used in all branches of the hygiene industry, whether in the food, beverage, pharmaceutical or chemical industries.
