High precision compact peristaltic pumps with stepper motor  -  BW100

NEW PRODUCT – Peristaltic Liquid Pump with Silicone Tubing. Move fluid safely from here to there with this very nice little pump. Unlike most liquid pumps, this is a peristaltic type – the pump squishes the silicone tubing that contains the liquid instead of impelling it directly. The upshot? The pump never touches the fluid which makes this an excellent choice for any food/drink/sterile based pumping such as for making drink-bots or gardening robots!

The pump is basically a geared down STEPPER motor, so it’s more precision. Inside the pump is a ‘clover’ pattern of rollers. As the motor turns, the clover presses on the tube to press the fluid though. The pump does not need to be primed and in fact can self-prime itself with water a half meter with ease. You can PWM the motor to speed up or slow down the flow rate and if you connect the motor the other way it will move fluid the other direction. Works great with either a power transistor (basic on/off) or a motor driver chip .

CR pump's silicon tube is the most commonly used material for peristaltic pump.
It provides the longest service life, and good chemical compatibility with aqueous and many organic solvents.
Its service life is about 150 hrs at 600 rpm and 825 hrs at 100 rpm.
It can usually be left running on experiments during weekends without much danger of rupture.
A fresh section of tubing should be pulled through the pump rollers before any running peristaltic pump is left unattended.
Silicone tubing can also be autoclaved a single time with a wet cycle without a significant reduction in its life.
High temperature and high pressure sterilization.
