Product Overview:
The 4951415 is PT fuel pump exclusively for Cummins CCEC KTA38-M2 marine main engines, and it is also compatible with KTA19-G2 constant-speed generator sets. Its primary operating condition is continuous alternating high-load propulsion of offshore vessels, followed by steady-state power generation for stationary industrial power stations. Its housing, internal flow rate and anti-corrosion performance are all calibrated for heavy-duty operating conditions featuring high vibration, salt spray and prolonged full-load operation.
