{"product_id":"sparkfun-gravity-digital-peristaltic-pump","title":"SparkFun Gravity: Digital Peristaltic Pump","description":"\u003cp\u003eDFRobot peristaltic pump integrates a PPM motor driver on the pump, this is a Gravity interface (PH2.0-3P) motor driver. The control signal is compatible with standard servo motor, you can use Arduino, Raspberry Pi, micro:bit and other kinds of microcontrollers to control its direction and flow speed. The tube in the pump head is made up of BPT material, which is anti-acid and long life.\u003c\/p\u003e \u003cp\u003ePeristaltic pumps are a kind of positive displacement pump used for delivering small amounts of fluid. The fluid is contained within a flexible tube fitted inside a circular pump casing. When the rotor rotates continuously, the fluid in the tube will be squeezed and deliver to the other side. In this way, the liquid flow rate can be easily accuracy controlled.\u003c\/p\u003e \u003cp\u003eAs a kind of metering pump, peristaltic pump can be conveniently used for quantitative delivery. It has a wide range of application scenarios, such as science experiment, hydroponics, drip irrigation, tropical fish farming, shrimp cylinder environment control, etc. A large number of titration experiments can be automated with this peristaltic pump, such as potentiometric titration, indicator-based colorimetric titration, pH-based titration, and so on. It is great helpful to improve your working efficiency. At the other hand, peristaltic pumps also have a wide range of applications in food, medical and other industries. Making an automatic coffee machine will be a really good idea!\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003e\u003cem\u003eAttention:\u003c\/em\u003e\u003c\/strong\u003e Since the motor power consumption (about 5W) is a little large, it�s better to add an external power supply on your microcontroller, USB port can only provide 2.5W power supply.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e1x Gravity: Digital Peristaltic Pump\u003c\/li\u003e \u003cli\u003e1x Digital Sensor cable\u003c\/li\u003e \u003cli\u003e1x Silicone tube (1m)\u003c\/li\u003e \u003cli\u003e1x 10mL plastic measuring cylinder\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003ePeristaltic Pump:\u003c\/strong\u003e \u003cul\u003e \u003cli\u003eMotor: DC Motor\u003c\/li\u003e \u003cli\u003eRated Voltage: 6V\u003c\/li\u003e \u003cli\u003eRated Power: 5W\u003c\/li\u003e \u003cli\u003eTube Material: BPT\u003c\/li\u003e \u003cli\u003eTube Specifications: inner diameter 2.5mm, outer diameter 4.5mm\u003c\/li\u003e \u003cli\u003ePump Head Material: Engineering Plastics\u003c\/li\u003e \u003cli\u003ePulsation: Three Rollers, Small Pulsation\u003c\/li\u003e \u003cli\u003eFlow: �45ml\/min (almost 1ml\/s)\u003c\/li\u003e \u003cli\u003eWorking Conditions: ambient temperature 0 ~ 40 �, relative humidity \u0026lt;80%\u003c\/li\u003e \u003cli\u003eThree rotors with moderate pulsation\u003c\/li\u003e \u003cli\u003eNon-toxic and pollution-free\u003c\/li\u003e \u003c\/ul\u003e\n\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eDriver Board:\u003c\/strong\u003e \u003cul\u003e \u003cli\u003eInput Voltage: 5V-6V\u003c\/li\u003e \u003cli\u003eMaximum Continuous Operating Current: 1.8A\u003c\/li\u003e \u003cli\u003ePeak Current: 2.5A\u003c\/li\u003e \u003cli\u003eQuiescent Current: \u0026lt;1mA (No PPM Signal Input)\u003c\/li\u003e \u003cli\u003ePPM Signal Resolution: 1us\u003c\/li\u003e \u003cli\u003ePositive Pulse Width of the PPM Signal: 500us-2500us\u003c\/li\u003e \u003cli\u003eForward Pulse Width Range: 500us-1400us (500us: max forward speed)\u003c\/li\u003e \u003cli\u003eStop Pulse Width Range: 1400us-1600us\u003c\/li\u003e \u003cli\u003eInverted Pulse Width Range: 1600us-2500us (2500us: max inverted speed)\u003c\/li\u003e \u003cli\u003ePPM Frequency: 50Hz (Servo Control Signal)\u003c\/li\u003e \u003cli\u003eConnector: Gravity PH2.0-3P\u003c\/li\u003e \u003cli\u003eSize: 27.4 x 28.7 mm\/1.08 x 1.13 inches\u003c\/li\u003e \u003c\/ul\u003e\n\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/wiki.dfrobot.com\/Gravity__Digital_Peristaltic_Pump_SKU__DFR0523\"\u003eProduct Wiki\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e","brand":"sparkfun-10","offers":[{"title":"Default Title","offer_id":40331934433365,"sku":"16898:WIG-16898:spark","price":10965.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/16898_-_Gravity_Digital_Peristaltic_Pump.jpg?v=1663614603","url":"https:\/\/www.tanotis.com\/products\/sparkfun-gravity-digital-peristaltic-pump","provider":"Tanotis","version":"1.0","type":"link"}
