<p>PURPOSE: To allow leaked fluid caused on a connecting surface and an abutment between parts of an insertion body to flow into a suction chamber of a pump so as to make a pump head part free from load fluctuation during the pump operation, in a high pressure plunger pump for work pressure requiring the high bar. CONSTITUTION: An abutment between both parts of an insertion body is provided in a chamber of a casing 1 connected to a suction chamber 26. A pump head part 2 is integrally formed, and a valve seat surface 16 of a discharge valve 5 is positioned in or near the separating surface between the casing 1 and the pump head part 2. Accordingly, a high pressure plunger pump can be used for the field for dynamically cleaning a concrete surface.</p> |
