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.

V-SP Series Vertical Split Case

The V-SP splitcase pumps are used in a variety of commercial, industrial & municipal applications whilst featuring vertical mounting to offer an ideal solution where job site space is limited. V-SP models allow the standard SP splitcase pump to be mounted vertically drastically limiting the floor space needed as compared to the standard SP product line.

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. Each model features 250# cast dimensional flanges and 420 stainless steel shafting.
