Name: IDP® WCC Between Bearings Pump - Horizontal, Multistage, Double Case
Brand: Flowserve
SKU: flowserve-558

الوصف

The WCC is a between bearing, multistage, double case, diffuser style barrel pump designed for medium duty applications in the oil & gas, chemical process industry and general industry markets. With numerous units installed, the Flowserve WCC(D) medium duty multistage barrel pump is a unique member of the double-case barrel pump family. The operating window is set out for the standard product range; however Flowserve has numerous installations in excess of this range what would be considered as fully engineered hydraulics and pump package. Features and benefits: - The rotor is built “in-line” or when required as an “opposed impeller” configuration. Precision cast Impellers of radial flow design. Individually dynamically balanced to G2.5 . Single suction first stage impellers on the smaller size and double suction is available on the bigger size types. Impellers are standard supplied with renewable wear rings on the front and back hubs, overlay material shall be selected to suit the application, DLD is the preferred method for applying hard coating of super duplex materials. Optional integral wear surfaces can be supplied. The standard rotor build is a stepped shaft design with shrink fit impellers individually keyed to the shaft. Impellers are secured against axial movement in in the direction of the axial thrust against the shaft shoulder. When required the impellers can be located to prevent axial movement in the reverse thrust direction by means of a split ring. - Barrel The WCC barrel is available as a casting with integral nozzles or a forging with weld on nozzles. The barrel is designed to suit service conditions with 10 incremental pressure steps. Suction flange and discharge flange can be rated to suit pump design pressure. The standard configuration is centre line mounted with Top/Top nozzles and is considered self venting therefore no vent connection is required. Alternative foot mounted option is available for low temperature applications and alternate nozzle configurations, like side/side, are available after engineering review. Discharge Head The discharge head consists of 2 configurations; - Conventional bolted head construction which combined with the center line mounted barrel allows for temperatures up to 425 ºC - Shear ring alternative for low temperature applications up to 120ºC with a foot mounted casing and optional nozzle orientation. The complete inner cartridge consists of: Impellers/Rotor Precision cast Impellers of radial flow design. Individually dynamically balanced to G2.5 . Single suction first stage impellers on the smaller size and double suction is available on the bigger size types. Impellers are supplied with integral wear surfaces on the front and back hubs, overlay material shall be selected to suit the application, DLD is the preferred method for applying hard coating of super duplex materials. Optional renewable wear rings can be supplied and would be shrunk –on and positively fastened (pinned by means of axial grub screws) to the impeller to prevent rotation and axial movement. The standard rotor build is a stepped shaft design with shrink fit impellers individually keyed to the shaft. When required the impellers can be located to prevent axial movement in the reverse thrust direction by means of a split ring. The alternative precision fit rotor incorporates a stepped shaft and impellers individually keyed to the shaft , impellers are secured against axial movement in both directions by means of split rings. Stationary Wear Parts Stationary wear parts consist of the front casing rings and back bushing rings. Stationary wear parts are shrunk and pinned ( axial grub screws) in the casing to prevent rotation. API 610 10th edition clearances are standard on the front ring with Flowserve standard clearances on the back bushing ring. Diffuser/Channel Rings Multi vane diffuser/ channel ring inter stage assemblies are used to balance radial loads throughout the pumps operating range. Low…
