Abstract

PURPOSE: To permit visual inspection of inner seal and obtain sure sealing performance after its inspection by forming a seal inspecting hole which extends to the outside between each sealing part through a barrel and allowing said seal inspecting hole to communicate to the low oressure side space through a pipe, in operation.
CONSTITUTION: A seal inspecting hole 12 which extends to the outside is formed at the near center between each sealing part 8a, 8b through a barrel 1, and a communication hole 13 which extends to the outside is formed in the space 4a on the low pressure side through the barrel 1, setting the seal inspecting hole 12 and the outer end opening part contiguous each other. In test operation, the seal hole 12 is set opened, and the inner seal is inspected visually through the leak from the seal inspecting hole 12 to the outside of the pump. After inspection, the seal inspecting hole 12 is interconnected with the low pressure side chamber 4a through the communication hole 13 and a pipe 14, then sealing pressure can be reduced in normal use, and sure sealing effect can be obtained.
