CR Peristasltic pump BT300FJ series with flowrate of 0.007-1140 ml/min. Multiple pump heads can be cascaded. Suitable for high precision and micro flow application .
Flow speeds can be adjusted either by hand through switching knobs, instead of the traditional way of membrane keypad, which reduces obviously the failure rate, or by automatic control through the external controller interface, with 3 available modes: 0-5V, 0-10V and 4-20mA. Memory function is also available in the product in case of power off. Besides, switching knobs are designed clearly so that it is easy to operate for customers.

Advantage of CR peristsaltic pump.
CR Peristaltic pump are easy to maintenance
replaceable tubes allow you to switch from one liquid to another in the shortest amount of time.
No need to rinse and disassemble after the flushable product, you only need to replace the peristaltic pump tubing
CR Peristaltic pump with high precisio
The calibration function can ensure the filling accuracy for each dose .The suckback function prevents liquid (reverse): in the dispense mode, after the end of the direct cycle, the return stroke is initiated to prevent the liquid from flowing out of the pump tube during the stop.
CR peristaltic pump are non-pollution: the fluid only contacts the pump tube and does not touch the pump body;
CR Peristaltic pump is Versatility
CR peristaltic pump can be used with a variety of products and can be used in a variety of industries.
CR peristasltic pump are easy to work
After the power is turned off and on, the control system maintains the current settings (pump head  tubing model and other parameter ).
CR peristaltic pump with good sealing: It has good self-priming ability and can be idling to prevent backflow.
CR peristaltic pump with Low shear: ideal for conveying shear sensitive, aggressive fluids


Suitable pump head :

 Multiple pump heads can be cascaded for 2/3 channels .

Noted :The inner diameter of the hose determines the flow rate; the wall thickness affects the ability of the hose to be compressed and rebounded, which also has a large effect on the life of the hose.

CR peristaltic pump tubing 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.

Peristaltic pumps are widely used in laboratories and scientific research institutions; chemical industry; construction industry; mining, metallurgy industry; paper industry; paint industry; food and beverage industry; ceramic industry; water treatment industry; biopharmaceutical industry; agricultural hydroponics industry; Equipment industry; industrial washing machine matching; packaging machinery industry, etc.
