I have information on the Birmingham Pump Co. including pictures of their pumps. Unfortunately the model numbers of the pumps are not included with the pictures. While I probably have a picture of your pump, I can't tell by the model number. Please send me a picture of the pump or better yet, please post the picture here on this site. This way if I can't help you, maybe someone else can.
