Abstract

PURPOSE: To maintain efficiency of a pump without replacing valve plates in such a way of forming the back sides opposite to the fixing valve plate and movable valve plate to the shape to be able to fix the seal mechanism in a rotary valve type plunger pump to feed muddy material, such as concrete, etc. under pressure.
CONSTITUTION: The outer peripheral part of the movable plate 11 on the side of the fixing plate 8 is surrounded by O-rings 32, 33, and O-rings 34, 35 are installed around the inner circumferential part. Grooves 36, 37 are arranged on the fixing plate 8 opposite to between these O-rings 32, 33, and between O-rings 34, 35, and grease is constantly fed through a pipeline 38 to these grooves 36, 37. Though this grease is, when water in the concrete muddy material is ready to rise above the O- rings, to seal them, at the same time, to play the role in lubricating on the contact faces with the fixing plate 8 and the movable plate 11. The grooves 36, 37 and each groove for the O-rings 32W35 are formed at the back sides of the fixing plate 8 and the movable plate 11, and in case where their sliding faces are worn away, they should be turned over, and can be used.
