Kp. Kovanda et al., Polyether polyol: An interim look inside the lead pump on a hydraulic automatic gauge control system, LUBRIC ENG, 56(11), 2000, pp. 25-29
This paper introduces a new generation, fire-resistant hydraulic fluid: pol
yether polyol. This paper highlights the internal inspection of a variable
displacement, axial piston pump that has operated for 4,000 hours at 345 ba
r (5,000 psi). The fluid is used in the lead pump operating on the Hydrauli
c Automatic Gauge Control system at Bethlehem Steel's 160" Plate Mill in Bu
rns Harbor, Indiana.
