Package Included
1pcs x DC40C-1240 12Vdc Micro Brushless DC Pump
Several notes about use of pump:
1. as micro brushless dc pump, land use or submersible installation can be both OK, but it cannot be self-priming, just make sure that fluid can actively flow passing through inlet/outlet because pump works via centrifugal force of high-speed rotation of impeller inside (push/throw fluid out). No long-time dry work without fluid, or it may damage the pump.
2. voltage of power supply should be stable and much higher voltage is prohibited, or pump's circuits inside may be burned. Directly connected with solar panel as power supply is not advised for the real vol. of power supply is not stable and change along with environment such as sunrise, etc; also, if battery with capacity of more than 10Ah is used as power supply, pre-measurement of real voltage is advised. It's because the real voltage of battery may be much higher than rated voltage when battery is in full charge & without voltage-limitation function. Please pay attention.
3. do not use AC power, the router power supply, computer power supply and other cats power supply because output of these power supply may have obvious AC component.
About ripple problem, which is problem-prone factor: many DC transformers are half-wave rectifiers, there exist obvious AC component in its "DC" output and pump may be damaged because of this! Brushless pump must be powered by full-wave rectified power supply.
4. about concept of max lift, it's not spraying height (big difference exist between the two concepts) and it means highest vertical distance water flow column can get inside pipe when pump works at rated voltage. Spraying height will be much lower than lift height.
5. pump can continuously work when fluid temperature is lower than 60-65C; if higher, only shorts time intermittent work is advised as kind of rest and maintenance, or pump's life span may be affected (the higher temperature, the higher possibility that life span will be affected)
6. It's out advised to have any articles inside the fluid environment and suitable filter is required when in relative long time work.
