• Five-stage fractionating jet purifies pumping fluid and assures low base pressure
• High tolerable forepressure
• Full thermal protection
• Fluid-level sight glass provides quick indication of pump fluid status at all times
• Fill and drain assembly for pump fluid
• Standard gauge port (NW-25) below inlet flange included
• Foreline baffle prevents loss of fluid into backing pump system
• Optional halo baffle reduces backstreaming without adding height
