K Series

Regular maintenance and timely troubleshooting are crucial for the reliable operation of marine-rated pumps in engine-room oil services. Kral's K Series pump is designed for marine environments and is suitable for handling fuel oil and lube oil. This pump employs a three-screw design and is driven electrically, making it a robust choice for engine-room applications. Common issues include screw wear from contaminated fuel oil, mechanical seal leakage, bearing wear due to poor lubrication, and relief valve malfunctions that can lead to pressure instability. To ensure optimal performance, it is recommended to keep spare parts such as seal kits, bearing kits, gaskets, relief valve parts, and screw sets on hand. Regular checks should include monitoring the pump's pressure, noise levels, and seal leakage, and overhauls should be conducted when there are drops in pressure or capacity.
