The directions of suction and discharge of the pump are all vertical and upward .with different stages selected according to the needed head.
Stator of the pump is composed of suction casing .mid-segment.discharge casing .end cover and bearing body.
Rotor of the pump is composed of shaft.impellers.sleeves,and balancing disk,The two ends are supported by the ball-bearings.
Paper gaskets are used on the contacting surfaces between the suction casing.mid-segment and discharge casing of the pump.They are sealed by tightening the bolts. ○ -rings are mounted on the interfaces between the sleeves to prevent water from entering the bearnjngs. ○ ilimmersed machine is sealing at the two ends the pump.
There are water cooling jackets around the bearing housings.when the temperature of liquid is higher than 80 ℃ ,Cooling water should be turned on to cool the bernings.
Calcium grease lubricant is firled into the bearing thrugh oil-cups.Viewing from the direction of the suction casing .the pump is rotating clockwise
