What is the minimum order?

Yes, our company mainly deals with wholesale deals. The MOQ as 1 piece.

How long is the warranty time for your products?

Our officially promised warranty time is one whole year after delivery at best.

Do you give any discount?

I'll surely try my best to help you get those by the best price and good service at the same time.

I would like to ask you if it's possible to have my logo on the product.

A: We hope you know that our company RUNZE FLIUD perfectly support customized logo service. But, we also hope you know that it's an extra service, so a little bit extra service fee is needed.

The liquid I use is relatively viscous, is it used for these peristaltic pumps?

It's nice to show us photos or videos about the liquid you are using, and then we can better help you choose a peristaltic pump .

Do you have a 220V power supply that matches the pump? Is there a European standard plug?

Yes, we have power adapters with European standard, national standard, and American standard to choose from

Is there any requirement for the thickness of the panel when using the bulkhead joint?

For the tightness of the connection, we recommend that the panel thickness is ≤14mm, 12mm<panel perforation diameter<14mm.

What should I do if I want to achieve multi-channel?

It can realize multi-channel connection with superposition of pump heads is very simple

Do I need to do anything to this pump to maintain it?

1. When not in use for a long time, please drain the liquid in the peristaltic pump tube in time, open the peristaltic pump protection lock, and loosen the tube of the peristaltic pump . 2. Regularly check whether the pipeline-interface is loose or damaged. If abnormalities occur, replace them in time.

How long the service life of the pump tubing be last?

The life of the pump tubing depends on the pump speed and pressure, the material and chemical compatibility of the pump tubing, etc. Different tubing come with different service life from hundreds of hours to tens of thousands of hours

What is the effect of pump speed on pump tubing life?

The lower the pump speed, the longer the pump tubing life

How to choose pumps with different motors?

1. Stepper motor, with low noise, high precision, a driver has to be used to control it 2. DC motor, with a commercial cost, not very precise as a stepper motor peristaltic pump .

How to Reduce Pulsation?

1. Use a pulse dampener 2. Add discharge tubing 3. Use dual heads with offset rollers.

What kinds of driver for options if we will use your peristaltic pump with stepper motor?

1. MC-20A, Voltage analog driver allow you to adjust the speed manually 2. DM422C, PWM driver allow you to use pulse signals to control the motor 3. MC-20T, protocols driver allow you to use RS485/RS232/CAN signals to controller the motor Welcome to contact our sale representative to get more specifications and the quotation

Any suggestions for microfluidic applications?

It depends on your accuracy requirements. Generally speaking, peristaltic pump can also be used in microfluidic application. However, if you have a very strictly requirements on the accuracy error, we suggest that you try our industrial syringe pump to achieve very high accuracy

How to Choose a Peristaltic Pump?

Before choosing a peristaltic pump , you should know clearly about the following points 1. What is the dosed liquid? Is it corrosive or viscous? 2. What flow rate is required (ml / min)? 3. Do you need the complete play and plug pumps or OEM pump head + motor for prototype design? 4. Is there any pressure at inlet and outlet? 5.Do you have your own driver, power supply to control the pump? 6. Is there any requirements on the suction and lift head? Welcome to send inquiry to our sale representative with the answers of above questions

How long is the warranty period of your products?

One year, excluding consumables such as tubing and plastic fittings, and damage caused by human and improper operation

What kinds of transportation you use?

Generally, we will ship by Express service, such as UPS / DHL / FedEx / TNT, to most countries, which generally takes 5-7 days to arrive. If these express are not available to ship parcels to your country, we will let you know and suggest other special-line transportation.
