| HYPRO D252 2-DIAPHRAGM PUMP, 6.1 GPM @ 290 PSI @ 650 RPM WITH 3/4" HB INLET, 1/2" NPT OUTLET AND A 3/4" SOLID KEYED SHAFT. Important Notes: The most common version of the D252GRGI is the 3/4" hollow shaft. You can determine the version you require by measuring the shaft on your gas engine. Another potential problem, you can not swap the gearbox from one D252 to another. So if you are replacing an existing pump, and your old pump had a gearbox, you must order the D252GRGI version. |
