Compliance and Restrictions


Sealless Magnetic-Drive Turbine Pumps
• Max. viscosity: 50 SSU Max. specific gravity: 1.2 Self priming TEFC motor enclosures Mount on 56C frames
Low-flow, high-head pumps deliver acids and caustics through piping systems with varying head conditions. High pressure capacities help extend filter media life with pulse-free flow in ultrapure filtration systems. Zero-emission, sealless magnetic drive system helps meet EPA regulations, while avoiding mechanical seal and power frame maintenance issues. Polypropylene housing, volute, and impeller. Sealed motor ball bearings provide continuous-duty service. Pumps are suitable for injecting cleaning agents in high head for food and beverage processes, including spray systems, low micron, and ultrapure filtration systems.
