ShurFlo 94-238-03 Diaphragm, Lower Housing & Drive Kit for 2088 Series 3.0 GPM Pumps

ShurFlo 94-238-03 lower housing and drive assembly kit for ShurFlo 2088 series 3.0 GPM diaphragm pumps. This is the three-chamber Santoprene diaphragm with its lower housing and drive plate — the wear parts that move the fluid. When a 2088 loses flow or pressure but the motor runs fine, or you see fluid weeping from the seam behind the pump head, the diaphragm is torn or the drive is worn, and this kit is the fix.

In stock at our Spokane, WA shop. Most 2088 rebuilds pair this with the Viton valve kit (94-232-05); add the pressure switch kit (94-375-05) and you've replaced every wear part on the pump for well under the price of a new one.
