Replacement parts for Hypro D19 and D19GRGI Diaphragm Pump.
The heads (part number 9910-800100) are no longer available, but can be replaced by using the D252 heads. Simply click the D252 diagram page below and choose part number 9910-801940 and either the two of the 9910-809060V valve assemblies for each head or the D252 Repair Kit which comes with valves.
Also note that the Hypro 9910-800230 Accumulator Head is no longer available. Use the Hypro 9910-809205 Accumulator Head as a suitable replacement.
When Hypro redesigned the D19 they retooled the heads, adding a more stable dual check valve system and renamed it the D252. You will note that aside from the heads, valves and oil sight glass, the 9910-D19 (or AR19 pump) and the 9910-D252 (or AR252) have the exact same parts.
