How should the operating weight of a pump be calculated?

1. What factors should be considered when calculating the “operational weight” of a pump? 2. Which specialty usually proposes the operation requirements for pumps? 3. Can it be calculated by multiplying the net weight by a percentage? This post was last edited by hutom123 on 2009-3-24 16:24]
What does “operational weight” of a pump mean? This is the first time I’ve heard of it! Could you explain to everyone what it means?
The operating weight of the pump should be provided by the designer and manufacturer of the pump, with main considerations including the weight of the pump body itself, the weight associated with heating, insulation, or cooling measures, the weight of the lubricating grease, the weight of the medium inside the pump, the dynamic loads generated during the start-up, stoppage, or operation of the pump, and the loads resulting from the pipes connected to the pump.
For the foundation of a pump, generally only two forces need to be considered: one is the static pressure, that is, the weight of the pump itself, and the other is the dynamic load, which is the inertial force generated when the motor rotates. When the motor has a high power rating (for example, 100 kW), this can be mentioned to the civil engineering team if necessary. When the pump head is high, the reseating force when the pump is stopped must also be taken into account. This post was last edited by QQ Ai on 2009-3-10 08:56.]
