Jabsco 15780 0000 - Cummins Vortex Marine Cooling Pump (K38/K50)
The JABSCO CUMMINS PUMP Model# JA 15780-0000 is a rugged marine raw water cooling pump engineered for Cummins diesel engines including K38, K50, KTA38, and KTA50. Built with a durable bronze body and flanged ports, this pump reliably circulates sea water for engine cooling, helping prevent overheating and supporting continuous marine operation. Its dual impeller design blends the self priming capability of a flexible impeller with the high flow performance of a bronze centrifugal stage, delivering up to 400 GPM of cooling water for demanding sea applications.
Designed for both professional vessel engineers, this unit also serves as a direct OEM replacement for Cummins part numbers 3393018, 4314820, and 4314522 - making it an ideal choice for maintenance, repower, or overhaul applications.
