ARO 637140-11 Neoprene Diaphragm Pump Kit Assembly
Kit assembly with Neoprene diaphragms and balls for ARO 66605J-311 and 666053-311 pumps.
All-Neoprene kit assembly for ARO 66605J-311 and 666053-311 diaphragm pumps, covering the diaphragm and check ball elastomers.
Built around Neoprene, the ARO 637140-11 kit assembly supplies diaphragm and ball elastomers for two pumps in the 66605 series. Both pump models end in -311, which lines up with the kit's -11 suffix.
Neoprene is a synthetic rubber. In the pump, the diaphragms separate the air side from the fluid side and do the pumping, while the balls act as one-way valves. Our listing does not break out the remaining contents of this kit, so check the technical data sheet if you need the item list.
Good Times to Fit This Kit
- Pumped material appears at the exhaust after a diaphragm rupture.
- The pump runs but cannot lift fluid from the supply.
- Neoprene parts have gone soft, cracked or out of shape in service.
