Centrifugal Pump · Pumps
The DESMI DK-300 is a centrifugal pump. It is normally installed in the engine room, pump room or auxiliary machinery space close to the system it serves. It is designed for continuous transfer or circulation of relatively low-viscosity liquids. In operation, a rotating impeller adds velocity and the casing converts it into pressure. Compared with neighbouring models, the relevant differences are flow, head, motor, materials, port size and impeller configuration; these must be confirmed from the installed documentation rather than inferred from the model designation alone. Service and survey attention should concentrate on suction/discharge condition, cavitation, seals, bearings, alignment and motor load. For exact ratings, dimensions, tolerances, test limits and model-specific settings, refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Trend suction/discharge pressure, flow where available, motor current, vibration, bearing temperature and leakage. Inspect strainers, valves, seals, bearings, coupling, foundation and rotation and verify standby/changeover arrangements for critical services. Apply pump-type-specific manufacturer limits during overhaul.
Carry seals or packing, gaskets, bearings, coupling elements, filter/strainer consumables and selected motor/starter parts. Critical duties may justify a spare impeller, rotor/stator, screw/gear set or complete pump according to the actual pump principle.
