Gear Pump · Pumps
On ships, the GV pump is commonly used for oil transfer, specifically handling fuel oil and lube oil. Designed to be marine-rated, it operates as a gear pump powered by an electric drive. Ensuring the pump's optimal performance involves maintaining a clean suction strainer and keeping the oil at the correct temperature and viscosity. During routine overhauls, it is essential to inspect the gears and the relief valve for any signs of wear or malfunction. Common issues include gear scoring due to contaminated oil, shaft seal leakage, and relief valve sticking, which can result in pressure loss from bushing wear. Critical spare parts such as seal kits, gear sets, bushings, and relief valve parts and gaskets should be readily available to address these potential failures promptly.
