new, the data tag on the pump: type 1059 35 l/min nr. 2787 021a 1500 min 15 bar. there is a tag on the cover but we can only read some of the end part of the part numbers, they are w-109-f35-1509, item # is 882014. nice heavy duty looking pump. mounting holes are 1/2", and are about 5-1/8" x 4-5/8" mounting pattern, looks like it fits into a hole 439220" in diameter or 125 mm. assume it built to metric standards.
