F Pump

Series 'F' Magnetic-Coupled Pumps are seal-less and "leak-proof" providing total solution containment. Available in two different materials of construction for a wide range of chemical and temperature compatibility. By using powerful rare-earth magnets, this pump provides flow and pressure equal to that of a physically much larger pump. This powerful coupling allows the pump to operate with the full size impeller at full flow while handling liquids up to 1.8 S.G. or 50 CPS. These powerful magnets create a balancing field which eliminates loading on bearing surfaces, thus providing an extended life span of the bushing compared to that of many standard magnetic coupled pumps. This same "balancing" gives the pump its ability to run dry for 10 minutes, or 30 minutes if wetted, before damage occurs. A fluted bushing provides positive internal liquid circulation/flush along the shaft spindle. These pumps utilize a high-purity ceramic stub-shaft which eliminates breakage. A unique feature of this pump is its ability to mount to NEMA and metric frame motors, thus giving motor options of TEFC, EXP, chemical duty and 575V. The pump is also available longcoupled. Standard models are constructed of chemically coupled, glass-filled PP or carbon-filled PVDF. O-Ring is FKM on both. Bushing material is high density carbon on both with flush groove for positive cooling. The casing thrust ring and spindle are fluoride-resistant ceramic. Maximum pump pressure: 35 psi (2.4 BAR) for 1 1/2" x 1 1/4" model, 60 psi (4.1 BAR) for 2" x 2" models. All of the flow curves illustrated are the result of impeller diameter trimming, thus a variety of flow and pressure conditions can be attained with a single pump and spare impellers. Motors are continuous-duty. Single phase motors are supplied with 8 ft. (2.4 m) of 3-wire cord and plug. 3-phase motors are not supplied with cord.
