The Weir Split Case series single stage double suction centrifugal pumps are designed and developed using advanced technology to meet demanding market requirements.

Photos: Above, installation of Weir Split Case pumps.

CASING The double-volute casing is designed to re-duce radial forces resulting in lower bearing loads and longer service life. Upper case is easily disassembled and adjustments made without disturbing suction and discharge piping. Pump inlet and outlet connections can be reversed to meet customers site requirements.

BEARINGS Standard construction includes oversized grease lubricated ball bearings. Oil lubricat-ed bearings are also available as required.

SEALING OPTIONS Stuffing box is available with either non-asbesto soft packing or a wide range of mechanical seal arrangements. The shaft is protected by a stainless steel shaft sleeve.

IMPELLER Dynamically balanced double-suc-tion impeller is designed using the latest in 3D computer technology to optimize hydraulic performance and minimize axial forces. Each impel-ler can be tailored to the customer’s design conditions.

BASEPLATE Minimum 3/8” thick fabricated steel construction suitably reinforced to support the full weight of the pump and motor.

SHAFT Alloy shaft is equipped with a renewable sleeve to protect the shaft from the pump liquid. Shaft is available in various materials ranging from (CK45) carbon steel to (420) stainless steel.
