The EDUR PBU multiphase pump is a single-stage peripheral centrifugal pump with the unique capability of being able to pump a liquid/gas mixture. The centrifugal pump is constructed of stainless steel, so may be used to handle a variety of liquids. Air, Oxygen, Carbon Dioxide and Ozone gases can be introduced into the suction line and transported and used to mix or disperse the gases. This makes the pump ideal for DAF plants, where the multiphase pumps provide the task of air saturation without the use of compressed air (no compressor, air saturation tank or associated controls).

Advantages include:

  • Liquid flows to 1 l/s
  • Gas content up to 15%
  • Stainless steel construction
  • Completely replace the “old” DAF system with a single pump

The EDUR LBU multiphase pump is a multi-stage centrifugal pump with the unique capability of being able to pump a liquid/gas mixture. The centrifugal pump is constructed of either C.I./ Bz/ SS, Nodular Cast Iron, All-Bronze, Stainless Steel, or Super-Duplex Stainless Steel construction, so may be used to handle a variety of liquids.

Air, Oxygen, Carbon Dioxide and Ozone gases can be introduced into the suction line and transported and used to mix or disperse the gases. This makes the pump ideal for DAF plants, where the multiphase pumps provide the task of air saturation without the use of compressed air (no compressor, air saturation tank or associated controls).

Advantages include:

  • Liquid flows to 16 l/s
  • Gas content up to 20%
  • Cast iron/Bronze/Stainless steel, Nodular cast Iron, All-Bronze, Stainless Steel, or Super-Duplex Stainless Steel construction
  • Completely replace the “old” DAF system with a single pump

Designing pumps since 1927, EDUR Pumpenfabrik has developed a range of pumps for use in refrigeration systems. They have been designed to provide a maximum level of safety, reliability and efficiency. They are the safe option because they use standard TEFC motors, which don’t need to be cooled using the pumped media. They are efficient because they use magnetic couplings. By using magnetic couplings energy is not wasted by pumping fluid over the motor [as with “canned motor pumps”] and back through to the separator.

Advantages include:

  • Suitable for ammonia, C02, synthetic refrigerants and refrigerants containing hydrocarbons/li>
  • No heat transfer from motor to pumped media/li>
  • Low maintenance/li>
  • Low NPSH values/li>
  • Pulsation free operation/li>
  • Long service life
