Diaphragm and drive kits

Q. Why don’t you supply the diaphragm on its own as it’s the part that has failed?

A. Failure of the diaphragm will allow liquid to come into contact with the bearing that is part of the diaphragm and drive kit. In our experience the bearing usually needs replacing shortly afterwards.  Furthermore the diaphragm is physically screwed to the drive plate, and the torque of the three screws effects the performance and flexibility of the diaphragm and pump.
