CONSTRUCTION

Sterling SIHI liquid ring vacuum pumps have a simple but robust

construction with the following features and benefits:

Near isothermal compression
Oil free, with no internal lubrication
Capable of handling almost all gases and vapours
Able to handle quantities of liquid “carry over”
Low maintenance and safe operation
Low noise and almost vibration free
Available in a wide range of materials
Broad range of applications
O-ring sealing as standard
Cavitation protection as standard
Drain hole as standard
Built-in solids drain
Rotating metallic parts are non contacting to minimise wear
ATEX compliance

Sterling SIHI liquid ring vacuum pumps of the range LPH 45008,

LPH 45311 and LPH 45316 are two stage pumps. In addition, the

LPH 45008 and LPH 45316 can be used as compressors without

any modification. (see the Technical Catalogue - Liquid Ring

Compressors)

APPLICATIONS

Evacuation and pumping of dry gases and saturated vapours. The

pumps can also handle liquids. These units offer pressures in the

range of 33...900 mbar(a) to atmospheric. Much lower pressures

are available by using ancillaries such as ejectors and lobular

boosting pumps. Typical application areas include:

Chemical and pharmaceutical industry for distillation, drying
and degassing
Food and beverage industry for low temperature cooking,
and bottle filling
Electronic industry for impregnation and drying
Plastics & Rubber industry for degassing
Healthcare for sterilisers and general vacuum

NOTE

By continuously feeding the pump with a small amount of service

liquid (usually water), the heat due to gas/vapour compression is

conducted away. This also replenishes the liquid ring and ensures

that it does not become saturated with process media. Recharging

the pump with service liquid at ambient temperature enables the

unit to condense evacuated gases / vapours. It can therefore be

used for solvent recovery. The condensed gas and liquid can be

separated in a liquid separator. More information is provided in the

accessory catalogues.

The integrated solids drain permits the removal of any entrained

solids whilst the pump is operating. The service liquid can therefore,
