S239 Release Collar is one of spare parts for 10/8ST-AH Horizontal Slurry Pump, and it's called Impeller Disassembly Device.
The Impeller Release Collar S239 is used for 10/8ST-AH Slurry Pump, 12/10ST-AH Slurry Pump and 14/12ST-AH Slurry Pump.
Impeller Release Collar is also called Impeller Disassembly Device, the basic code is 239, it allows impeller to be removed easily in large slurry pump. Slurry pump impeller release collar is located between labyrinth and shaft sleeve, it is made up of three segment.
Slurry Pump Impeller Disassembly Device parts code: FAM239M, S239M, T239M...
10/8ST-AH Centrifugal Slurry Pumps are the most comprehensive range of centrifugal slurry pumps for use in mining, chemical, mineral processing and general industry applications. The horizontal slurry pumps are designed for heavy duty applications such as mill discharge, power sector and tailings as well as specialty applications, which are used for continuous pumping of high abrasive, high density slurry.
Design Features:
Wetted Parts:
Impellers - wide variety of metallurgic and elastomeric options (metal and elastomer interchangeable) – pump out vanes on rear and front (on closed impellers) reduce recirculation within pump, and aid in preventing seal contamination - optional castings of straight or semi-Francis vanes (from 3 to 8 vanes on certain sizes) offer wider hydraulic options in single sizes
Liners - wide variety of metallic and elastomeric options (metal and elastomer liners are interchangeable) to select from in order to provide the longest wear life possible
Seal Arrangements:
Expeller (Centrifugal Seal) – no external sealing water required where applicable
Stuffing Box - flushed gland sealing with braided packing and a lantern ring
Mechanical Seals
Bearing Assembly
Cartridge - style bearing housing allows for removal from pump and assembly in controlled environment
Oversized shaft diameters and reduced overhang in the wet-end contribute to long life and reliability in the field
