FAQ

Q1: Is 3800975 a marine water pump?
A: It is marine‑grade fresh coolant pump for closed‑loop cooling, **not a seawater pump**. It handles only engine antifreeze; marine service needs an extra raw seawater pump.

Q2: Difference between 3800975 (Long Nose) & 3800974 (Short Nose)?
A: Same hydraulics, impeller, seal and housing. Only hub extension differs: 3800975 is 4.26‑inch long‑nose. Non‑interchangeable. Mis‑fit leads to belt misalignment, early bearing failure and fan collision.

Q3: What are its working conditions?
A: For heavy‑duty continuous operation. Temp: 85‑105°C; Pressure:1.0‑1.5 bar. Fits high‑vibration, long‑duration full‑load environments.
