Three screw pumps for machinery lubrication
In addition to the traditional horizontal mount,
KRAL three screw pumps are available in freestanding vertical
configuration as well, saving valuable space on the lube skid. Three
screw pumps are available in iron or steel case configuration.
Flow range from 4 to 3,410 l/min. and discharge pressure to 100 bar can
be attained at nominal motor speeds without the requirement for speed
reduction gears.
The three screw pumps can also be directly mounted on an auxiliary shaft
from the rotating machine being lubricated at speeds up to 6,000 min-1,
provided a sufficient suction pressure level to avoid cavitation.
The low velocity and pulse free flow of the KRAL three screw pump
assures low noise operation and freedom from cavitation.
