Pumps can be a stand alone product, Two Pumps, or a combined product such as a Motor Coupling Pump.
A Pump is connected to a Pressure and Flow hydraulic load. A stand alone Pump can be connected directly to motor, or it can be connected to one or more transformation stages.
Depending on the pump type, flow direction may only be allowed in one direction, while other pumps allow for bi-directional flow.
A Motor Coupling Pump is selected as one combined product with a unique Vendor Model. The combined product can be with or without a coupling, as defined in the CombinedProducts table in the database.
