摘要： An agitator (20) for agitating drilling fluid (24) or other slurries or mixtures in a tank (25) includes a pressurised and fluid-free compartment (32) within the tank (25). The motor (37) driving the agitator (20) is housed in the fluid-free compartment (32). Control apparatus (75,70,65) senses fluid levels (50) and, in conjunction with a compressed gas source (80), maintains the compartment (32) fluid-free. Additionally, when the fluid level (55) in the enclosure (25) drops to a predetermined minimum, the speed of the agitator (20) may be slowed.
