Abstract
An improvement in a liquid metal mechanical pump which includes a hydrostatic bearing immersed in liquid to rotatably support the lower end of a pump drive shaft and is constructed such that a part of liquid forced out of a diffuser is supplied to the bearing to lubricate it by the liquid. A cylindrical partition wall is disposed around the bearing with a clearance therebetween. The areas inside and outside the partition wall are communicated at a position remote from the diffuser. The partition wall prevents the liquid discharged from the diffuser from being directly supplied to the bearing, thereby reducing thermal shocks to the bearing.
