KRAL three screw api pumps are especially suitable for the transfer of separated crude oil. The three screw api pumps can handle a wide range of viscosities and differential pressures. With a high flow rate and an excellent NPSH value, KRAL api pumps are manufactured in accordance with European and American standards.
KRAL three screws api pumps offer a significant price advantage compared to other types of pumps. KRAL three screw api pumps are used to flush the pipe system with separated crude oil from the storage tanks on a regular basis. Our api pumps are well suited for pipeline booster applications in pumping stations. Due to their design, KRAL api pumps can handle separated crude oil with a wide range of viscosities and can generate high differential pressures even when pumping very light crudes.

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 api 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 api pumps are very safe and offer full control in all types of operational modes. The api pumps have a linear delivery rate characteristic with fine adjustment. With KRAL api pumps, you can reduce maintenance costs and optimise the total cost of ownership. For bitumen production, KRAL offers solutions with conventional seals, and api pumps with magnetic couplings are also available to provide solutions for specific customer requirements.

A challenge in compressor designs is the high feed pressure to which the pumps are exposed. This in turn represents an enormous demand in terms of selecting sealing methods as well as the overall construction of the pump. High inlet pressures can also lead to great stress on the bearings and seals in many pump designs, negatively impacting the lifetime of pumps and seals.
KRAL three screw pumps with magnetic coupling overcome these challenges. Magnetic couplings can eliminate stress on bearings, and additionally such seals guarantee operation free of leaks. For standard use in compressor lubrication, we also offer solutions with conventional seals.
