Super silent noiseMaterials:pump head Nylon, membrane EPDM / PTFE, valve EPDM / FPM Note:other water flow rates of 0.05L/0.15L/0.2L/0.3L can be customized as requirements. C- inside controller type D- outside controller type
Motor type and code:"C"means Coreless brushless DC motor with dual ball bearings (long lifetime>15,000hours) "D"means 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.
1. Oilless, environmental protection media, can be used in the food industry
2 .Diaphragm liquid pumps have good self-priming function
3. Can run dry, there is no danger or damage
4. 24 hours continuous running is workable (will not stop working because of overheating)
5. Compact design
6. Can be made by PTFE (polytetrafluoroethylene) membrane, FPM valve (FKM), which are the good materials of anti-acid and alkali
7. Patented diaphragm structure, long maintenance-free life expectancy. ( if want to replace the diaphragm by your own, just need unscrew the head screws and do the replacement)
1.Adopt enhanced importing dual bearings, which arevery wearable, can well match with 15,000 hours pump lifetime & .
2.Adopt metal balance cake, the the pump has good balance performance, very small vibration. (Domestic counterparts with plastic weights, has big vibration
3With imported rubber diaphragm, high purity, good wear resistance. Besides, there is EPDM, PTFE valve, EPDM, FPM diaphragm optional, all these materials have better chemical resistance capability..
4 The overall design & inner structure are the same as foreign famous KNF, Parker brands, the overall design is reasonable & compact, which assured TOPSLFO pumps’ high performance and low noise, low vibration and long lifetime.
5.Our Micro Diaphragm Pumps are available with a choice different drive motors.
A- Premium duty brush DC motor
lifetime 5,000hours,longer endurance lifetime than other normal DC membrane pump
B- Economical brush DC motor
C- Coreless Brushless DC Motor
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- 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
