Its aluminum center body and colorless polypropylene fluid section, combined with PTFE diaphragms with Santoprene® backup, PTFE check balls, and polypropylene seats, provides a durable fluid-handling configuration for a variety of applications.
The three-piece manifold design provides a flanged connection configuration, while the bolted construction and ball-check design support dependable operation and convenient serviceability. This pump is suited to common transfer, recirculation, filling, and supply duties across chemical, industrial, water/wastewater treatment, and other process environments.
Application suitability should be confirmed based on the specific fluid, concentration, temperature, chemical compatibility, solids content, and operating conditions.
