33L/min Digital Filling Peristaltic Pump




Related Application

CR peristaltic pump LG350FJ with 2 work mode . one is for liquid constant transfer ,another is for bottle filling . that can run with KZ50 pump heads, with flow rate from 10-35000 ml/min. 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 three 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

The main parts of KZ50 pump head are made of aluminum alloy and stainless steel, which meet the requirements of GMP standards and can be applied in the fields of pharmaceutical and food with hygienic grade requirements. The pump head adopts a structure in which the pressure block is separated from the pump body, and the surface of the pump body is painted and painted, which is both elegant and easy to clean. KZ50 pump head also has the characteristics of large flow range, stable and reliable operation, corrosion resistance, etc. At the same time, according to the needs of users, the dual pump head can be used in series.

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.
1. Two kinds of operating modes, transferring and dispensing, can be switched freely, to ensure the quantitative distribution of the fluid.

2. Applicable pump heads: KZ50.

3. With both-way large torque, low power motor. It can be connected with several pump heads to satisfy the different demands of the flow rates.

4. FULL SPEED button available for filling in & emptying out the tubing quickly.

5. Long life, digital rotary knob; the revolving speed can be continuously adjusted by hand, or to preset distribution frequency, time, interval and back suction angle.

6. Memory function available in case of power off and it will continue the work once the power was restarted.

7. Supports MODBUS communication protocol through the DB15 interface of the drive. And communication protocols customized is available.

8. Good cost performance.
