| " P " means pressure pump, " / V " means vacuum pump, "6/12/24" means different voltages optional. | |||||||
| Pump Weight:250g; Pump Size:80mm*30.5mm*58mm; Inlet&Outlet:OD 4.8mm/ID 2.6mm,hose suggestion:ID 4.0mm | |||||||
| Super silent noise < 50dB from 1 Meter; Materials:pump head Nylon, membrane EPDM / PTFE, valve EPDM / FPM: Good resistance and tolerance with alcohol, acid, alkali, oxidant, ketone and fat, etc. Poor oil resistivity. | |||||||
| Motor type and code :"C":Coreless brushless DC motor with dual ball bearings (long lifetime > 15,000hours) "D": Coreless brushless DC motor with dual ball bearings + outside controller (long lifetime > 15,000hours);pump with outside controller can realize functions of PWM 0 ~ 5V speed adjustment, brake, instant starting work ; inner controller is no additional functions. | |||||||
Our Micro Diaphragm Pumps are available with a choice of different drive motors.
A-Â Premium duty brush DC motor
lifetime 3,000hours,longer endurance lifetime than other normal DC membrane pump
B-Â Â Economical brush DC motor
lifetime:1,500hoursÂ
C-  Coreless Brushless DC Motor Â
A brushless electronically commutated dc motor (electronics integrated in motor), the motor runs vibration and spark free, almost silently, is very dynamic and extremely durable, ideal life-time 15000 hours
D-Â Coreless Brushless DC motor with outer controller
With all advantages of coreless brushless DC motor, ideal life-time 15000 hours, and outer controller can realize more control functions of PWM or 0 -5V speed adjustment, brake, ~ instant starting work
H- Brushless DC Motor
Long lifetime 10000hour
