Xylem 436981 NEMP 80/6 Magnetic Drive Centrifugal Pump — Marine air conditioning circulation, ice makers, hot water circulation, livewell and bait tank installations. As a Centrifugal Pump, it is normally installed in the engine room, pump room or auxiliary machinery space within the liquid service defined by the vessel piping arrangement. In that role, its primary purpose is to move liquid continuously by converting impeller rotational energy into flow and pressure. Compared with positive-displacement pumps, a centrifugal pump depends strongly on adequate suction conditions and system resistance. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Inspect suction condition, strainers, seals, bearings, coupling, alignment, foundation and casing leakage. Trend pressure, flow, vibration and motor load where available. Confirm valves are correctly positioned before running and investigate cavitation promptly. Refer to the manufacturer documentation for the exact figure for clearances and wear limits.
Carry mechanical seals or packing, bearings where appropriate, coupling elements, gaskets, wear rings and impeller service parts where vessel criticality justifies them.
