MRA Micro Gear Pump / Micro Flow
MRA Micro Gear Pumps can solve the working situation of 1ml-2000 ml/min flow, 0.5-25bar pressure difference and 0.4-3000m.Pas viscosity (similar to water).The pump can withstand a pressure of 4 MPa.
JONSN precision micro gear pump circulation pressurization systems, automatic feeding (dosing) systems, sampling equipment (including vacuum environment sampling), laboratory equipment, cooling systems (refrigerant circulation pumps), Hemodialysis and Peritoneal Dialysis ,casting machinery, Packaging machinery, cleaning systems, additives filling systems, chemical metering systems, small test/pilot test equipment, etc., require small flow, high pressure difference, no leakage, stable flow, precise metering, and no pulsation transfer pump.
- Flow range: 0.001-48.5 l/m
- Inlet pressure: -0.9-10 bar
- Pressure difference: 0-25.5 bar (depends on material viscosity)
- Temperature: -20-160 (other temperature customized)
- Viscosity range: 0.4-3000 cps
- Max. gravity: 1.8
- Motor options: AC motor, Brushless DC motor, Servo motor, Inverter explosion-proof motor
- Inlet & outlet thread: NPT1/8", 1/4", 3/8", 1/2", 3/4"
- Non-standard customize: OEM machine ancillary, and servo system.
Explosive view:
- Preset step/servo motor speed, adjust pump flow.
- 2. Remote control pump on/off.
- Support RS485 MODBUS communication protocol.
- Wide displacement range: 0.18ml/r-17ml/r(Meet the request of most micro flow).
- High pressure differential: 10-25.5 bar(Normal), maximum 4Mpa.
- Long service life: Gear& shaft adopt reinforced PEEK gears + high strength nano ceramic shafts combination, which are more wear resistant and greatly improved the service life of the pump. High gear consistency and interchangeability: Processed by Japanese precision CNC hobbling machine, gear consistency and interchangeability is high.
- Temperature range: -120ºC to 180ºC, we use high-performance magnetic material, improve inner magnet over molding process, completely solve the problem of high temperature thermal expansion and bulging.
- High wear-resistance: By the use of high quality bearing grade PEEK modified material (confidential formula), relevant data is available. Wear resistance is ☆☆☆☆☆ by using of nano-ceramic shaft while using SS316L is ☆, and ceramic is ☆☆.
- Long time operated under 100ºC ambient temperature.
- Strong ability of industry application and accurate pump selection data analysis by software instead of experience only.
- Comprehensive testing ability for all elements and the testing result is traceable in the systems.
- High Gear accuracy testing capability by the German Winzer Gear Testing device.
- Service life: >20000 hours while others normally 6000-8000 hours.
