This NBR (Buna-N) seal kit, number 31040, is the standard seal kit CAT Pumps lists for its 3531, 3531C, 3535, 3535C and 3537 pumps. It contains the seals, O-rings, V-packings and backup rings shown in the photos. A kit like this is installed when the pump drips between the manifold and crankcase, pressure fluctuates or output drops.

Before you order: check the model plate on your pump against the five models above. Note that CAT Pumps here is the pressure pump maker, not Caterpillar equipment. NBR suits water and many common fluids; confirm the seal material is right for what you pump.

New, open box; the kit is in a sealed package. Ships from Kansas City, MO with tracking.
