Zusammenfassung:PROBLEM TO BE SOLVED: To provide a pump device with cooling piping that can simply remove such a measure of heat generation as is from a speed reducer smaller in heating value than an engine and the like, without requiring a space for the arrangement of equipment such as a cooling unit and an in-pipe cooler. SOLUTION: The pump device has an inspection hole 16 inside a pump 11, a cover 20 for closing the hole, cooling piping 21 secured to the wetted surface side of the cover, and an inlet 22 and an outlet 23 located on the outer side of the cover for liquid circulated in the cooling piping.
