The Liverani SEP Series are close coupled, Stainless Steel AISI 316 side channel pumps, benefitting from a hygienic design. These liquid ring pump are frequently used in many industries for a variety of transfer and offloading applications of clean, low viscosity fluids such as fresh water, sea water, light hydrocarbons & oils, alcohols, acids, solvents & edible fluids such as oils and juices. They are also able to handle liquids with up to 50% gas content and high temperature fluids allowing liquids to be pumped closed to boiling point.

The SEP side channel pumps are an incredibly robust and versatile pump, offering a varied flow and head range as well as motor voltage options and control options. Many are supplied with a carrying handle as standard making them useful as portable site pumps, and they can also be supplied with trolleys and inverter driven as well for variable capacity control. ATEX versions of these side channel pumps are available, see GR ADPE Range.

Features of the SEP Series Liquid Ring Pump:

  • Close coupled, stainless steel liquid ring pump
  • Self priming up to 6m without the need of a non return valve
  • Reversible operation
  • Low risk of cavitation due to low NPSHr
  • Short period of dry running
  • Hygienic construction for food grade pump applications
  • Transfer of fluids with up to 50% gases and vapour in suspension without a pulsing effect
  • Single bearing and sealing construction up to EP MASTER 2”, EP70 & EP80 units fitted with double bearing and sealing construction - reducing shaft deflection and wear & increased leakage protection
  • Manual by-pass option on bronze units for manual adjustment of capacity.
  • Supplied with BSP M Fittings as standard and free issued hose tail / pipe fittings. Can be supplied with a variety of food grade connections and also custom welded flange configurations. 
  • Operating Speeds up to 3000 rpm
  • Wide range of voltages, 12, 24, 110, 230, 230-400V & 400-690V in AC & DC
  • Casing Drain, Food Grade Trolleys and Food Grade Enclosure options for food industry
  • Connection types available DIN, BSP Male & female, Triclover, SMS, RJT, Friederich, Macron, Garolla
  • Available accessories include temperature sensors, pressure switches, level sensors, timer switches for set times, remote controls and radio control
  • Pumps can be supplied free standing, with base plates, on trolleys and even with carrying handles for smaller models
  • Various Stainless Steel AISI 304 Pipe Fittings for easy integration of the pump into existing applications are available on request to match any of the above connection types.

Thanks to the following features the Liverani SEP side channel pump is an option that can be applied to many application requirements.

  • Hygienic construction - The Stainless Steel model is food grade making it safe for use with products for human consumption. Tri-clamp coupling available.
  • High entrained gas capabilities - Liquids with up to 50% gas content can be handled without any dry run damage e.g condensate
  • Low NPSH required - Can pump liquids close to boiling point without risk of cavitation such as LPG 
  • High temperature handling - Liquids can be transferred at temperatures up to 165°C which is where other pumping technologies fail
  • Reversible operation – Allows cleaning solution to be ran through after use for hygienic pump applications, and tank to tank transfer applications.
  • Self-priming up to 6m – Enables the emptying of tanks and drums without a non-return valve or regular manual priming being required.
  • Various accessories available - Trolley for portability, bypass valve for nozzle dispensing, control panel, variable speed drive, level sensors and dry run protection

Like centrifugal pumps, side channel pumps have narrow tolerances that make them suited to only clean, low viscosity fluid free from solids. However, their uses do vary. Firstly, side channel pumps can handle high temperature fluids that are pumped close to boiling point and also can pump fluids that contain up to 50% gas content with little interruption to fluid flow. Their hygienic design and their reversible operation means that the Liverani SEP liquid ring pump is ideal for the below applications:

Marine Applications: Industrial Applications:
  • Fresh and sea water pump
  • Boiler feed
  • Condensate extraction
  • Aquaculture recirculation systems
  • Low viscosity fuel and lubrication transfer
  • Hot water transfer
  • Condensate extraction
  • LPG
  • Low viscosity fuel and lubrication transfer
  • Process water and chemical pumping
  • Corrosive acids and solvents
  • Juices, edbile oils and drinks manufacturing
  • Refrigerants and coolants
