Pump control and monitoring
When a sealless pumps is specificed the Number One user concern is safe and leakfree operation, especially when noxious, toxic, carcinogenic and other hazardous materials are conveyed. The ICM has been designed such that most condition monitoring and speed control devices can be easily and economically installed and retrofitted. The following condition monitoring options are available:
- Pump Speed Control (Hydrovar® , PumpSmart® etc.)
- Temperature Monitor
- Flow and filling level monitor
- Pressure Monitor
- Motor load monitor
- Can temperature monitor
- Can leakage sensor in the lantern
- Rolling bearing monitor
- Connection for external flush supply
- Customized solutions on request.
- Secondary Sealing: The space around the can be sealed against the rolling bearings by means of special shaft or labyrinth seals.
If the can is damaged, the drive side and atmosphere would be protected against the medium for a certain time. Therefore, in conjunction with one of the monitors, this results in an effective preventitive enviromental protection in the case of critical media.
Inducer
Optional suction inducer available.
Reliable Cartridge Plain Bearings
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 abrasion-resistant 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.
Hastelloy Separating Cans
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 analysed using a computer. The can is, therefore, optimally designed.
- 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!) between the can and the inner magnet assembly allow for greater reliability in solid laden services or with higher viscous media
