An insert member for use in a flexible diaphragm portion of a pump which enables such flexible diaphragm portion of such pump to be provided with a substantially uniform non- obtrusive surface area that will be positioned in such pump for intimate contact with a material to be pumped. Such insert member includes a first disc-like portion having both a first predetermined size and a first predetermined configuration. There is also a second disc-like portion having both a second predetermined size and a second predetermined configuration. The second disc-like portion is secured adjacent one surface thereof to a first surface of the first disc-like portion and such second disc-like portion extends from the first surface of such first disc-like portion for a predetermined distance. This second disc-like portion is disposed substantially in a center portion of the first surface of such first disc-like portion. A plurality of apertures are formed through the first disc-like portion which have a third predetermined size and a third predetermined configuration. This plurality of apertures provides an overall predetermined open area through the first disc-like portion for receiving a rubber compound therein and thereby significantly improve bonding of the improved insert type member to such flexible diaphragm portion of such pump. A securing means is engageable at least with the second disc- like portion for securing the insert member to an elongated piston rod-like member disposed for reciprocal movement within such pump.
