What happens inside?
• Operates with the Alcap principle, thus no gravity disc
• No level ring
• Centrishoot
– Complete displacement
– Complete ejection
– Clean bowl!

question
• Which other separator for marine and power use has the oil paring disc inside the top of the disc stack?
MSPX

question
• No level ring!
• Why has the level ring been removed?
A level ring is not necessary in this separator design .

• 1 - Water outlet closed
• 2 - Oil outlet closed
– opened at pressure increase signal from PT4 in oil outlet.
• 3 - Oil displaced
– Displacement volume based on calibration of water flow at first start-up.

Oil/water back pressure, tube position, Appendix 4
• Previous separator models
– Increase oil back pressure increases water pressure
– FOPX, water indicating pressure increases when recirc holes in heavy phase paring disc become blocked
• Separation unit
– when oil pressure is increased the water pressure decreases

Oil/water back pressure, tube position, Appendix 4
• Water paring chamber
– Low oil back pressure
– gives a large diameter water ring

Oil/water back pressure, tube position, Appendix 4
• Water paring chamber
– High oil back pressure
– gives a small diameter water ring

Oil/water back pressure, tube position, Appendix 4
• Paring tube position
– large diameter gives high pressure
– tube out gives high pressure
