High Flow Sealless Magnetic Drive Pump
SLM-NVO
Klaus Union's SLM-NVO is a horizontal, sealless centrifugal pump with permanent magnetic coupling, for general services requiring zero leakage. The NVO-series complements the ANSI-dimensional hydraulics of the popular SLM-AVO series with higher flow rates and delivery heads.
Operating Parameters
- Flow rates up to 18,000 GPM
- Total delivery heads up to 700 feet
- Temperature ratings from -185 °F (-120 °C) to +572 °F (+300 °C)
- Flange rating per ANSI B16.5 Class 150 and Class 300
Pumping
- Aggressive, explosive and toxic liquids
- Acids & lyes
- Hydrocarbons
- Heat transfer liquids
- Liquid gases
- Difficult-to-seal liquids
- Ultrapure liquids
Applications
- Refineries
- Chemical and petrochemical industries
- Refrigeration and heat engineering
- Liquid gas plants
- Galvanic engineering
- Power stations & solar thermal fields
- Tank installations
- Pharmaceutical industries
- Fibers industries
Construction
- Horizontal sealless centrifugal pump with enclosed impeller
