Rotary Lobe Pumps For Isocyanate
Also know as TDI, MDI, or diisocyanate - isocyanate is used as a hardening or curing agent in polyurethane foams, industrial coatings, elastomers, inks, and resins. Isocyanate is mixed with a reactant such as polyol to harden or cure, which requires non-pulsating flow to ensure a proper mixing ratio. Isocyanates are extremely sensitive to moisture and hydrocarbons in the air - making airtight sealing critical. There are also health and safety concerns - making a sealless mag-drive highly desirable.
Bonve has rich experience in handling isocyanate and can provide customers with a variety of solutions to maintain products and safety.
About Isocyanate:
1. Also know as TDI, MDI, or diisocyanate.
2. Used as a hardening or curing agent in polyurethane foams, etc.
3. Mixed with a reactant, such as polyol, to harden or cure.
4. Requires non-pulsating flow to ensure a proper mixing ratio.
Isocyanate Challenges:
1. Extremely sensitive to moisture and hydrocarbons in the air - making airtight sealing critical.
2. Health and safety concerns - making sealless mag-drive pumps highly desirable.
Working Principle
Bonve lobe pumps basically consist of two lobe rotors, which rotate synchronously driven by a pair of synchronous gears in the gearbox. The rotors are driven by the main shaft and sub-shaft to rotate in a synchronous reverse direction, which changes the pump capacity, builds up high vacuum and discharge pressure, thus an efficient pumping is formed. Gap is kept between the rotors and between the pump casing, no friction, long life, no damage, no physical and chemical reaction to the pumped products.
