VI Series
Water Savers with Internal Water Restraining SystemSingle-stage liquid ring vacuum pumps with valves
in close coupled version with mechanical seal→ page with U.S. Units Performance data | | | Max. suction capacity | between 2.2 m³/h and 55 m³/h | | Min. inlet pressure | down to 33 mbar | | Possible media | dry and humidified gases | | Sound pressure level | 65 - 68 db(A) at 80 mbar | Temperature of
operational liquid | up to 80 °C | Temperature of
absorbed gas | up to 120 °C |
| Design | single-stage pumps in inverted design with valves and internal water restraining system
ATEX approval for the entire series:
device group II, device category 2/2G,
type of protection IIB, temperature class T4 | | Motor | 0.12 - 2.2 kW / 0.16 - 3.0 HP
AC / three-phase motors | | Materials | non-ferrous metal / stainless steel | | Connections | G 1/8 to G 1 | | Shaft sealing | mechanical seal | | Dimensions | refer to brochure | | Weight | refer to brochure |
| Advantages | - water saving: at suction pressures < 600 mbar, the water can be completely retained in the pump
- low noise due to optimized hydraulics and separation
- low calcification risk and easy temperature control possible
- easy disassembly due to inverted design and
O-ring sealing
|
| Possible applications | - extruder degasification
- sterilization of surgical instruments, textiles and beds (steam and gas sterilization)
- evacuation in central vacuum systems
