MP1 Multiphase Twin Screw Pump

Brand: Flowserve Corporation

The MP1 is a double suction, twin screw pump designed for continuous service in high viscosity applications where multiple phases are expected.

With its unique double case design, it acts inherently as a separator to run multiphase products up to 100% gas void fractions at a wide range of flow rates, pressures, and viscosities.
  • Double-Suction Design Provides Balanced Hydraulic Loads By Channeling Incoming Flow To The Screw Inlets At Each End Of The Pump.
  • External Bearings And AGMA 11 Timing Gears Are In Separate Oil Reservoirs To Eliminate Exposure To The Pumped Fluid.
  • Versatile ISO 21049/API 682 Seal Chamber Readily Accommodates Multiple Seal Types And Meets HSE Regulations Without Modification.
  • Split Bearing Bracket Construction Facilitates Easy Maintenance Of Individual Bearings And Mechanical Seals.
  • Modular Non-Welded Casing Is Available In Multiple Standard And Specialty Alloys.
  • Nozzles Integral To The Outer Casing Insulate The Inner Casing From Piping Loads, Helping To Maintain A Non-Contacting Shaft Design.
  • Screws Integral With Shaft To Prevent Deflection During High Loading.
  • Unique Dual Case Design Retains Liquid For Operation At High GVF In Multiphase Applications.
