Liquid Ring Vacuum Pump
The DSV Double Stage and SSV Monoblock Single Stage Liquid Ring Vacuum Pumps from Haberg are robust pumps that operate oil-free and require minimal maintenance. Both are designed to run smoothly and quietly across various industries, including chemical, pharmaceutical, and wastewater treatment. The main difference is that the DSV Double Stage can achieve a deeper vacuum level, while the SSV Single Stage features a compact monoblock design. Both models offer reliable and efficient operation.
Description
Specification
Downloads
HABERG® Liquid Ring Vacuum Pump are adaptable to most duties, with appropriate selection of materials & service liquid.
- Oil-Free Operation
- Applied to almost all gases and vapours
- Gases being pumped can be saturated with vapour
- Small quantities of entrained liquid can be handled
- Compression of gases and vapours being pumped is nearly isothermal
- Reliable operation with minimum maintenance
- Low noise and vibration levels
Standard Execution
The HABERG liquid ring vacuum pumps (LRVP) are of the double-stage displacement type. The only movable parts are the shaft and the vane wheel impellers. They do not touch the stationary pump parts. Both shaft ends run in antifriction bearings. For sealing, mechanical seals are applied.
Performance
Using water with a temperature of 15 °C as service liquid and a pressure of 1013 mbar at the discharge branch, the lowest suction pressure achievable is 33 mbar. With other service liquid, such as oil, which has a low and stable vapour pressure, deeper vacuum of 25 mbar (abs) may be achieved.
