High viscosity Lobe Pump for polyurethane polyol

Seiken rotary lobe pumps can be used in a variety of processes and their reliable mechanical seals and low shear flow characteristics are ideal for transferring urethane, urethane polyol, polyether and polyether polyols. Can help users improve production efficiency and ensure safety.


Stainless steel High viscosity polyurethane polyol transfer pump

High-viscosity lobe pumps are widely used in the chemical industry. Because of their slow running speed, they are especially suitable for media that are prone to foaming, high viscosity, high concentration and strong wear resistance. Polyurethane is widely used in manufacturing. They can be used in pressure sensitive adhesives, floor and carpet backing, and even paint to ensure it becomes a solid when spread into a thin layer. Seiken chemical grade lobe pumps are efficient transfer!

Saiken rotary lobe pumps are widely used in the food industry. mainly because of the following characteristics:
■High sanitation: The wetted parts are manufactured in stainless steel 304 316 or 316L.
■High smoothness: surface roughness is below 0.8  μm, confirming to 3A, EHEDG, FDA standard.
■Meet CIP and SIP requirements.
■Simple disassembly and asembly, easy maintenance and few wearing parts.
■Low speed, low shear, no damage to the pumped products.

Saiken 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.
