C starch

A large wheat mill uses a Börger ONIXline rotary lobe pump for conveying very abrasive C starch. C starch is produced when wheat starch is separated from the wheat gluten. When a specified fill level has been reached, the C starch is conveyed from an underflow tank into the product tank. The rotary lobe pump operates 24 hours on 7 days a week for 365 days a year. The speed and, thus, the flow rate are regulated by means of control technology. The pump is equipped with Börger double-acting mechanical seals as cartridge versions. The seals are pressurized by a barrier pressure system. This prevents any pumped medium from penetrating between the sliding surfaces of the seals. The pump has operated without interruptions since its installation.
