Detail
A water pump is a mechanical device that transports or pressurizes liquids. It transmits the mechanical energy or other external energy of the prime mover to the liquid to increase the energy of the liquid. It is mainly used to transport liquid, including water, oil, acid-base liquid, emulsion, suspended lotion and liquid metal.
It can also transport liquids, gas mixtures, and liquids containing suspended solids. The technical parameters of water pump performance include flow rate, suction head, head, shaft power, water power, efficiency, etc; According to different working principles, it can be divided into types such as volumetric water pumps and vane pumps. A positive displacement pump utilizes changes in the volume of its working chamber to transmit energy; Vane pumps use the interaction between rotating blades and water to transfer energy, and there are various types of pumps, such as centrifugal pumps, axial flow pumps, and mixed flow pumps.

| Setting | Pump Characteristics Curve | Function |
| AUTO | Propotional pressure curve descending from highest to lowest | The Autoadapt function automatically controls the pump performance within the specified performance range. (1 )Adjusting pump performacne according to the system sizing; (2)Adjusting pump performance according to the variation of load history.When it comes to autoadapt, the control mode of the pump is propotional pressure control. . |
| PP1 | Min .propotional pressure curve | The operating performance point of the pump moves forward or backward along the minimum propotional pressure curve， depending on the heat demand. The pressure of puma decreases at falling heat demand and increases at rising heat demand. |
| PP2 | Middle .propotional pressure curve | The operating performance point of the pump moves forward or backward along the middle propotional pressure curve， depending on the heat demand. The pressure of puma decreases at falling heat demand and increases at rising heat demand. |
| PP3 | Max.propotional pressure curve |
The operating performance point of the pump moves forward or backward along the maximum propotional pressure curve, depending on the heat demand. The pressure of puma decreases at falling heat demand and increases at rising heat demand. |
| CP1 | Max. propotional pressure curve |
The operating performance point of the pump moves forward or backward along the maximum propotional pressure curve, depending on the heat demand. The pressure of puma decreases at falling heat demand and increases at rising heat demand. |
| CP2 | Middle.constant pressure curve |
Based on the heat demand of the system, the operating performance point of the pump moves in or out the middle constant pressure curve. The pressure of the pump stays remain irrespective of the flow. |
| CP3 | Max. constant pressure curve |
Based on the heat demand of the system, the operating performance point of the pump moves in or out the maximum constant pressure curve. The pressure of the pump stays . remain irrespective of the flow. |
| III | Rate III | The pump runs at certain speed and performs a constant curve. For rate川mode, it means the pump performs the maximum curve under all operating conditions. To set the pump to rate |I| mode for only a short period of time means rapid pump venting. |
| II | Rate II | The pump runs at certain speed and performs a constant curve. For rate II mode, it means the pump performs the medium curve under all operating conditions. |
| I | Rate I | The pump runs at certain speed and performs a constant curve. For rate I mode, it means the pump performs the minimum curve under all operating conditions. |
 |
|
The night setback is automatic under certain conditions, where the pump runs with minimum performance and energy consumption. |
