Centrifugal Pump · Pumps
Alfa Laval ALP 15 is a centrifugal pump. It is normally installed in an engine room, pump room or machinery-space piping system close to the circuit it serves. Its purpose is to move a continuous liquid flow through shipboard cooling, bilge, cargo-support or other auxiliary systems by converting impeller rotation into fluid pressure and velocity. The centrifugal hydraulic element depends on adequate suction conditions, correct rotation and clear flow passages; the exact casing, impeller and priming arrangement are model-specific. The exact model designation and the listed power, medium or duty distinguish this unit from neighboring pump sizes; refer to the manufacturer documentation for the exact flow, head and material data.

What our service work and the manufacturer documentation say about keeping this model running.
Inspect suction strainers, valves, seals, bearings, coupling alignment, foundation bolts and visible casing condition. Trend suction and discharge indications together with vibration, noise and drive load where available. Verify the pump is correctly primed or flooded as required and that no persistent air ingress is present. Check for shaft leakage, abnormal bearing temperature and deterioration of coupling elements. Inspect the hydraulic parts when performance declines or internal damage is suspected. Refer to the manufacturer documentation for exact clearances, alignment criteria and wear limits.
Keep shaft-sealing components, bearings, coupling elements, casing or cover gaskets and pump-specific wear parts recommended by the manufacturer. For critical service, an impeller or rotating assembly may be appropriate depending on redundancy and onboard repair capability. Confirm all parts against the exact pump model and serial number.
