Water-transfer performance is defined by both flow and head. Maximum flow is measured under favorable conditions; as vertical lift, hose length and system resistance increase, actual flow falls. Buyers should define the required transfer height and distance before choosing a pump.
Use this table as a first screening tool. Final configuration, accessories, packaging and compliance requirements should be confirmed in the quotation.
| Model | Max flow | Head | Battery | Motor / protection |

| TOPFENG2622
FlowMove 21V Brushless Cordless Water Transfer Pump High-flow cordless transfer pump with dry-run and overheat protection. |
36 L/min | 12 m head | 21V 1500 mAh | Brushless 3820 |
Head is the vertical height a pump can overcome, expressed in metres of water. It is different from horizontal hose length.
TOPFENG2622 is specified at up to 36 L/min flow with a 12 m head, using a 21V brushless motor system.
No. Flow generally decreases as head and system resistance increase, so real operating conditions should be defined before selection.
The current FlowMove specification lists dry-run and overheat protection.
