$35.50
AR45 Pump Head AR3120020 #31. A major structural component of the pump assembly.
Crankcase and manifold components are the structural core of a triplex pump. Damage here usually traces back to something else — water in the oil from failed seals, a seized bearing, or a freeze event. Replacing the component without correcting the root cause means doing it again.
Before fitting a major pump component, identify what caused the original failure. Water in the crankcase, running dry, and freeze damage all leave evidence worth finding.
Grime Task Force stocks pump and drive components because these systems are designed to be serviced, and the difference between a machine that lasts five years and one that lasts fifteen is usually whether wear parts got replaced on time.
