BQ80S Microflow Variable-Speed Peristaltic Pump

BQ80S speed-variable peristaltic pump in the previous generation on the basis of the appearance design optimization and product function upgrade, low flow rate of 0.001-32 ml/min, speed accuracy<±0.2%, added mobile phone App remote control, locked rotor alarm, leakage alarm and smart functions, human-computer interaction more friendly. BQ80S is used for precise transmission of small flow liquids and high precision dispensing, suitable for instrument matching and laboratory use.

Flow: 0.001~32ml/min
Max: 3 Channels

 Functions and Features

  • Using the cortex m3 core processor, the running speed is fast and the device speed accuracy is high.
  • LCD display, switching between Chinese-English interface, simple parameter setting, intuitive state display.
  • Mobile App remote control (optional), the remote pump operation can be realized by using Lead Fluid APP software. It also has monitoring functions such as operating status (optional).
  • locked rotor alarm, leakage alarm (optional). And send the alarm signal to your mobile APP, remind you to deal with it in time, avoid unnecessary losses.
  • The hose life alarm function dynamically calculates the remaining service life of the hose and reminds you to replace the hose in time.
  • Added slow stop function to make the equipment run more reliable.
  • Start/stop, reversible direction, full speed and adjust speed, state memory (power-down memory).
  • External analog adjust speed, external control start-stop, reversible direction, external control signal physical isolation.
  • The type of external speed control signal (voltage or current) can be switched on the control panel.
  • Dustproof and moisture-proof circuit board design, external control signal supports 5-24V wide voltage input, super anti-interference characteristic.
  • Design of injection housing, effffectively prevent the erosion of various organic solvents, easy to clean.
  • RS485 communication, MODBUS protocol is available, easy to connect with other equipments.
  • Open multiple control parameters, suitable for ODM custom applications.

BQ80S Suitable pump heads and tubing, flow parameters

Drive type Pump head Ch Tubing size(mm)       Flow    rate(mL/min) per channel


(Pump heads notinter changeable)

DW10-1 1 WALL:0.8-1 ID: ≤3.17      0.001-32
DW10-3 3 WALL:0.8-1 ID: ≤3.17      0.001-32

Above flow parameters are obtained by using silicone tube to transfer pure water under normal temperature and pressure, in actually it is effected by specific factors such as pressure, medium, etc. Above for reference only.
