HYBRID DOUBLE CONTAINMENT SHELL

Pumping aggressive, explosive and highly toxic liquids requires the highest level of process safety. To protect people and the environment, leakage of the pumped liquid must be avoided - including in the event of a pump failure. For these most critical applications a magnetic drive pump equipped with a monitored, double containment shell still remains the safest solution.
To reduce the heat generated by a purely metallic, double containment shell and at the same time to improve the overall efficiency of the pump, Klaus Union has developed and patented a new hybrid double containment shell.

The hybrid double containment shell combines two separate shells.The inner shell is a highly corrosion resistant metallic containment shell while the outer, secondary shell is a non-metallic containment shell made from heavy duty technical ceramics.

Advantages:
- Reduced heat input into the pumped process liquid
- Increased reliability when pumping liquids close to their boiling point
- High corrosion resistance
- Higher efficiency leading to power savings
- Wider application range than full metal, double containment shells
- Fully compliant with requirements for secondary containment system as defined by API 685, 2nd Edition, § 3.66 (page 10)
- Primary and secondary containment integrity is
constantly verified by the pressure transmitter
- Easy and reliable detection of containment breach through a standard pressure transmitter
- High spare parts availability by using of standard Klaus Union components
- Ability to flush the area between shells
(according API 685, 2nd Edition, § 6.7.9)
- Available across entire Klaus Union mag-drive pump range
- Reliable and maintenance friendly construction

Application Coverage
- Pressure Rating: max. PN 40 (40 bar at 120 °C / 580 psi at 248 °F)
- Temperature Range: - 60 °C to + 400 °C (-76 °F to +752 °F); higher on request
- Pump Speed: up to 3600 rpm
