  • Glycol PumpsOperating Pressure: 100 to 2000 psiCirculation Rate: 3 to 450 gph

  • A pump used for circulating glycol within a dehydration system.A pump used to circulate amine within a desulphurizer system.What is a Glycol Pump?

  • FeaturesNo auxiliary power required

    Eliminates need for level control and dump valve at absorber

    Low gas consumption

    Completely sealed system prevents glycol loss

    Only two moving assemblies

    Hydraulic cushioned check valves withremovable seats of hardened stainless steel

    Circulation Rates: SC Series 8 - 200 gph PV Series 3 - 450 gph
