Air Section Repair Kits

EXPSeries Air Section Service Kit includes gaskets, 'O' rings, 'U' cups and the Simul-Shift® valve guaranteeing an ultra-positive, reliable shift signal that avoids stall-out.

PROSeries Air Section Service Kit includes the proper gaskets, 'O' rings and 'U' cups needed to complete standard maintenance repair.

Enhanced Fluid Section Repair Kits with their associated ball check seats can be purchased as an option. These comprehensive Fluid Section Kits are needed in some applications where ball check seats are worn due to long service life or in applications where abrasive fluids are being pumped. The offering includes the most common Fluid Kits with a wide range of non-metallic seats.

Order the kits with the same part number nomenclature as the pump where in the case of EXP series the 6, 7 and 8position respectfully calls out the seat, ball, and diaphragm material.
