The exploded views for Cornell pumps are separated by the type of pump you own.
1) Model Number: ex. 4NMPP - a 4" product pump
2) Frame Size: F5, F12, F16, F18
3) Grease or Oil Lubrication: If there is a "K" after the frame size, then it is oil lubricated. If there is no "K", then it is grease lubricated.
Select the button below which matches the description of your pump (look for model number, frame number, and packing or seal) to see the exploded view with parts list. If you want specific part numbers, please send the pump serial number to firstname.lastname@example.org. She will send you the bill of materials for your pump.
