Type MW

Product Description

This type mostly is applied in mature fields with declining reservoir pressure. In order to optimise the production, it is essential to reduce the wellhead backpressure. Additionally it is used to recover vapour from the casing annulus, e.g. with pumped wells, and in thermal operations using cyclic steam stimulation (CSS, huff n’puff) or steam assisted gravity drainage (SAGD).

The maximum allowable working pressure is 50 barg or acc. to ANSI B16.5 300 lbs. respectively.

Principles

Principle
  • Rigid Construction due to welded casing,
  • pressure rating up to ANSI 300lbs
  • (up to 50 bar operational pressure),
  • simple "in field" maintenance due to replaceable liner,
  • optimal material selection due to engineered rotors,
  • non contact pumping elements, forced lubrication system and/or
  • cooling system not required,
  • single acting mechanical seals with pressure less buffer fluid
  • system acc. API plan 52 or clean fluid injection acc.to API plan 32

Applications

  • Up- and Midstream
  • Conventional
  • Heavy Crude Oil
  • Petrochemicals
  • Thermal Operations
  • Wet Gas Compressions
  • Offshore Topside
  • Pipeline
Advantages
  • Self-priming
  • High viscosities possible
  • Low pulsations
  • Low noise level
  • Dry running possible
  • Constant flow on varying pressures and volumes
