First, peristaltic pump and gear pump compared

Peristaltic pump can replace gear pump application examples:

A quality control technique requires a drink to be pumped from the sample pool of a spectrophotometer at a flow rate of 0.8 to 1.2ML/MIN. The technician wishes to transmit another blank solvent simultaneously at the same flow rate.

For the above example to compare the advantages of peristaltic pump:

1, sample replacement quickly - only need to replace the pump tube

2, dual channel pump can achieve simultaneous transmission of sample and blank solvent

3, change the size of the pump tube or adjust the driver speed to achieve different flow rates

For the above example gear pump shortcomings:

1, before replacing the sample need to wash the pump carefully

2, there is no dual-channel function, technicians need to adjust and operate two



Two, peristaltic pump and screw pump compared

Peristaltic pump can replace screw pump application examples:

A food manufacturer needs to deliver high viscosity food grade adhesives to a labeling machine. The adhesive is applied to a stick, which is then applied to an adhesive plate, from which a thin layer of adhesive is applied to the bottle.

For the above example to compare the advantages of peristaltic pump:

1. It can handle high viscosity fluids well

2. Easy to replace pump tube, simple to clean pump, low maintenance

3. Pump tube compatibility reaches food level

For the above example to compare the shortcomings of screw pump:

1, high viscosity fluid

2, difficult to clean

3, internal component compatibility does not reach food grade

4. Limited automation capability



Three, WL600 peristaltic pump VS diaphragm metering pump

WL series peristaltic pump can replace diaphragm metering pump Application examples:

Sometimes in the chemical reaction process to the reaction tank to supplement acid and alkali must be implemented metering operation, the user in the comparison of WL series peristaltic pump drink diaphragm metering pump performance finally choose peristaltic pump.

For the above example to compare the advantages of peristaltic pump:

1, the fluid only flows in the tube and does not contact the pump body, without any seal

2, with the total function and quantitative timing or constant speed operation function

3, high control accuracy

4. Acid and alkali resistant pipe can be selected

5, the higher protection level is suitable for humid environment

According to the above example, the shortcomings of diaphragm metering pump are compared:

1, sealing corrosion resistance is difficult

2, can only roughly express the flow rate, can not control the total amount

3, can not be used in harsh working conditions

4, adjustment and control is not convenient
