Bitumen is primarily obtained as a vacuum residue in the vacuum distillation of petroleum. Here only special varieties of crude oil can be used – almost exclusively varieties of crude that are high in sulphur. Bitumen mainly consists of high molecular weight hydrocarbon and contains small quantities of sulphur, oxygen and nitrogen. The medium is highly viscous and reaches a fluid consistency only under high temperatures. KRAL three screw pumps have the capacity to operate within a wide range pressures and product viscosities. These are excellent features when it comes to pumps used in the loading and unloading of bitumen.
KRAL three screw pumps are very safe and offer full control in all types of operational modes. The three screw pumps have a linear delivery rate characteristic with fine adjustment. With KRAL three screw pumps, you can reduce maintenance costs and optimise the total cost of ownership. For bitumen production, KRAL offers solutions with conventional seals, and three screw pumps with magnetic couplings are also available to provide solutions for specific customer requirements.
