CE DC24V OEM micro fluidic piston plunger pump 
MP Series Micro plunger pump is a small volume, high precision, long life products series. Mainly for equipment and instruments matching application.
It can transfer liquid less than 5ml. The users can drive the stepping motor to control it, or choose other driver. There are two kinds of drive to choose:
12.5-QD1 Without locked-rotor (speed range: 0.75-450rpm)
12.5-QD2 with locked-rotor (speed range: 90-450rpm)
Those two models have Electromagnetic valve drive interface, have RS485 communication interface. Address can be set, can connect more than 32 set pump.
Electronic locked-rotor protection function, It will stop working when locked-rotor.
