-A comprehensive range of materials and accessories are offered to meet customer needs for a wide range of applications
-Integrated possibilities to connect safety and monitoring devices
-Design standardization and simplification to provide for easy maintenance
Plain bearings must run reliably. If, however, pump maintenance is required, it must be performed correctly and often as quickly as possible. The cartridge plain bearing system of the ICM is designed accordingly:
-Fast and simple installation and replacement of the plain bearings, no need for installation settings
-Cartridge design can be rebuilt/refurbished with individual components to minimize spare parts and repair costs Radial and thrust plain bearings made of highly abrasionresistant pure silicon carbide (SSiC) with universal chemical resistance
-In case of a plain bearing failure the encapsulated cartridge design both will act to contain possible silicon carbide (SSiC) fragments and to prevent the inner magnet assembly from contacting the can
-Optionally the Dryguard PLUS bearing system can be supplied to provide an optimized dry-running capability. Dryguard PLUS has proven its worth in thousands of operating chemical process pumps
A reliable flush circuit is important for heat dissipation, lubrication of the plain bearings and solids handling without clogging. The heat produced in the metallic can by eddy currents must be controlled to prevent against flashing because dry-running/inadequate lubrication and overheating are the most important causes of sealless pump downtimes and failures.
Coupling years of ITT’s sealless pump experience and using modern CFD (comutational fluid dynamics) methods, an effective and reliable flush circuit has been designed during the development stages of the ICM. The flush circuit is enhanced by special design features in the inner magnet assembly, can and plain bearing cartridge to guarantee reliable pumping even under the most demanding applications. Rigorous testing has been completed to confirm its reliability.
The can is the most important sealing element against the atmosphere. This component was thus carefully examined during the development phase. The pressure and flow conditions inside the can were illustrated, simulated and analyzed using a computer.
-Hastelloy C4 (2.4610) as standard, deep-drawn non-welded design for reliable corrosion resistance
-Vortex breaking bead at the bottom of the can prevents against erosion of the can
-Burst pressure > 150 bar (> 2,175 psi)
-Large clearances (1.5 mm/ 1/16”) between the can and the inner magnet assembly allow for greater reliability in solid laden services or with higher viscous media
Based on extensive testing the ICM has shown to be capable of pumping liquids which contain highly abrasive powders without any breakdowns or detectable signs of wear. Admissible solids contents need to be checked case by case.
-Precision-cast stainless steel, optionally Hastelloy and other material
-Back vanes or balance holes reduce axial thrust
-Optional suction inducer: – reduces the NPSHr by 35-50%, permits smaller pumps at higher speeds = lower costs, is advantageous for media with gas content
-Standard Pure Silicon Carbide SiC (SSiC), highly abrasionresistant, with universal chemical resistance
-Cartridge design eliminates measurements and fitting for simplified maintenance
-Optional Dryguard PLUS dry-running bearing system provide added safety during upset conditions
-High level of safety even in the event of plain bearing failure
-Minimum corrosion allowance: 3mm
-Standard 3/8” housing drain connection
-Replaceable housing wear ring (optional)
-Integrated connections for pressure and temperature monitors
-Jacketed housing for media heating or cooling on request
-Inner magnet assembly with encapsulated magnets
-Integral axial vanes assure positive pressurized flushing flow to both lubricate and cool the plain bearings
The ICM utilizes the same hydraulic components offered on the mechanically sealed IC series. Users benefit from reduced repair parts inventories due to this hydraulic design standardization
The ICM is prepared for the attachmen installation of a variety of monitoring and control devices.
-Hastelloy C4 (2.4610) as standard
-Non-welded, deep-drawn one-piece construction
-Rated for an operating pressure of 25 bar (360 psi), burst pressure > 150 bar (2175 psi)
-Standard grease-for-life bearings
-Options: flood oil lubrication with extra large oil volume, oil sump cooling, labyrinth oil seals
Integrated possibilities for connecting
-Plain bearing flushing feature with external medium, on request with can drain
-Temperature monitoring
-Coupling ratings of up to 330 Nm (100 kW at 2900 rpm), variable through modular design
-Integral outer thrust ring prevents against contact with the can in the event of a roller bearing failure, Spark-free as an option
• The number of “loose” components has been minimized due to its modular design concept
• High component interchangeability within the frame size groups
• No special tools required
• No fitting measurements
• Split lantern/bearing pedestal design: Allows for maintenance of the drive side while keeping the liquid end assembled and pressurized (“back pull out design”)
