Silicone Pump Insulation Covers

Silicone Pump Insulation Covers

Pump Insulation Covers, Made with Silicone & PTFE coated fabric for insulation blanket.

Pump Insulation Covers, made of PTFE or Silicone impregnated on both sides or one side fiberglass fabrics. Due to this insulated fabric is anti-aging, anti-environment, anti-corrosion, non stick and heat resistant. So it is used for the outer protection for the insulation covers. And the working temperature of PTFE coated fabric is up to 600F, the maximum temperature of silicone impregnated fabric is 500F.


What is Pump Insulation Covers?


Youngsun’s pump insulation covers are custom-created by designers who know exactly what to consider in making the highest-quality, best-fitting removable blankets for each pump.


And Youngsun’s Silicone impregnated(coated) fabric, is the best Anti-aging, Antiseptic, Heat-resistant, weather resistant and soft insulator, which is used to make the outside jacket for the pump insulation system.

Youngsun’s YS9038HD is PTFE impregnate(coated) fabric, which has higher heat-resistant property than Silicone coated fabric, so it is used for insulation system which need higher temperature and harder surface.


All the basic fiberglass is satin weaved, which ensure the highest tensile strength of the covers(blankets), and Silicone & PTFE coating is flexible in order for making blankets into any different shapes and sizes.

Application for Pump Insulation Covers


Removable Insulation Jackets are designed for Pumps, pipeline, valves, freeze protection and so on.

And Different color is for different application, like Yellow insulation jacket is for Gas, Oil and Steam value, pumps and so on.



Pump Insulation Covers could also be used for making Antiseptic Insulation Tent, which could be used to store chemicals(especially for flammable and combustible chemicals), or easy-corrosive, hazardous article.
