The AMT Cast Iron 1750 RPM Solids Handling End Suction Centrifugal pump delivers high efficiency performance that minimizes operation and energy costs. Built to last, each pump features a precision cast bronze impeller that is dynamically balanced to minimize vibration and maximize motor bearing life. Pull-from-rear design simplifies maintenance without disturbing piping connection. Gauge taps at the suction and discharge ports allow for system monitoring. Maximum 1\/4″ diameter solids handling and optional seal flush\/air relief valve is available for vertical installations. Pumps require a flooded suction and positive suction pressure.<\/p>\n
