usedtoolman 19 #1 Posted March 18, 2015 Here are six different O&R pumps. I don't know how many different ones were produced though I have seen at least 2 more. The blue one has no nameplate. Going clockwise from there they are a Keene Engineering, a Cenatron, a Kenco, a Comet and an ElectroFlow. I never cease to be amazed by how many different companies used these little engines. 2 CNew and pmackellow reacted to this Share this post Link to post Share on other sites
