SP Series Horizontal Split Case
SP Series Horizontal Split Case
The SP splitcase pumps are used in a variety of commercial, industrial & municipal applications. This heavy wall, Francis design, enclosed, bronze impeller provides a very broad operating range. The casing features an exclusive Thru-Bore line boring machining operation that greatly simplifies manufacturing and maintenance. Bearing & bearing housings can be inspected and/or replaced without removing the top part of the casing. The rotor assembly also features completely removable and replaceable packing housings/seal chambers with a replaceable vortex suppressor. The centerline of the pump has also been increased to ensure that suction and discharge flanges do not interfere with the pump foundation. Each model features 250# cast dimensional flanges and 420 stainless steel shafting.
