• Five-stage stainless steel fractionation nozzle can purify pump oil
• Overheating protection
• The liquid level sight glass can quickly indicate the pump oil level at any time
• Pump oil injection and discharge assembly
• The optional halo baffle water-cooled cap reduces oil return without increasing height
• Provide a standard gauge port (NW-25) under the inlet flange
• Optional quick cooling coil
