High pressure pumps, valves, gauges and sensors are most reliable when operated in clean, well-filtered fluids or gases. When pressure testing is required using aggressive media, there is also a need to prevent sensitive pressure equipment being contaminated.

We can integrate a pressure media separator into our pressure control system; maintaining precise pressure control, without subjecting equipment to media that could damage or cause premature wear.

Two Types of Pressure Media Separator Are Available from KW Designed Solutions:

Integral Rubber Bladder

Inside the pressure vessel, a balanced flexible rubber bladder acts as the separation element between aggressive test media and clean pressurisation media

We have designed a range of unique innovative high pressure chemical seals that allow the use of standard pressure instrumentation with aggressive test media such as H2S

Remote Accumulator

External of the pressure vessel; available as a piston, bladder or diaphragm type

Integrated pressure media separator into our pressure vessel and control system; maintaining precise pressure control, without subjecting equipment to media that could damage equipment

Features

  • Chemical Seals Suitable for Pressures Up To 1700 Bar
  • Compatible with Corrosive Media Such as H2S
  • Compatible with Seawater, Sand and Silt
  • Remote Accumulator Available as Piston, Bladder or Diaphragm Type
  • Suitable for Pressures Up To 22,500 PSI (1550 Bar)
  • Two Types of Pressure Media Separator: Remote Accumulator or Internal Rubber Bladder

Benefits

  • Chemical Seals Provide a Clean & Adequate Interface for Installation of Standard Components, e.g. Pressure Gauge, Pressure Transmitters When Working with Corrosive Media e.g. H2S
  • Internal Rubber Bladder Removes the Need for A Secondary H.P Accumulator – Providing A Low-Cost Solution with Less Maintenance & No Requirement for Extra Certification
  • Provides A ‘Clean’ Pressure Control System for Robust Operation
  • Remote Accumulator Maximises the Pressure Vessel’s Working Volume

Applications & Customer Uses

Pressure vessels and pressure control systems, which are supplied with pressure media separators are a very popular choice with customers who work within the subsea and materials research sectors.

For our subsea customers who test in simulated turbid seawater; internal rubber bladders separate the clean pressurisation media, from the aggressive sand and silt.

Material research organisations can carry out sour service testing in HPHT autoclaves using our unique chemical seals; allowing installation of sensitive pressure measuring instrumentation.

We have designed, developed, manufactured and supplied complete HPHT test systems for simulating downhole sour gas environments; complete with a special purpose chemical seal. The chemical seal is rated for 1700 bar at 300°C, with wetted components manufactured from hastelloy (C276) material.
