The casing, backplate and intrigalimpeller/stub shaft are cast 316L stainless steel for extra strength and resistance to line shock and corrosion.Large bearings and shaft provide positive alignment and minimize vibration.The casing is clamped to the motor adapter bracket (close coupled) or bearing housing (base mount) for easydisassembly while permitting 360 degree rotation of the discharge port.200 Series pumps are available with three standard seal types.Type 1- Single mechanical seal, external mounted and balanced.Type 1C- Single mechanical seal with water cascade flush.Type 4 - Double mechanical seal with flush housing.All seal components are interchangeable between models. All seal assemblies utilize an externally mounted,balanced rotary seal for longer seal life and better sealing capability. The stationary seal face is reversibleand replaceable.200 Series pumps are designed for a broad range of sanitary and industrial applications. Sanitary modelsare designed for clean-in-place and meet U.S.D.A. and 3A Standards.MANUAL CONTENT NOTE:This Manual addresses metric impeller shaftdiameter and contains basic information ontotal metric pump system requirements(page 26-27).Maintenance procedures do not cover Asepticor High Pressure pump applications.
