RO Pump Manufacturer: The Ultimate FAQ Guide

If you need any information about RO pump manufacturers in China, you will find the information right here.

Additionally, the guide also covers critical aspects of RO pumps.

So keep reading to learn more.

Are RO Pumps From China Manufacturers Genuine?


Our RO pumps are genuine pumps and you can verify by yourself through different ways.

You can visit our factory and examine our products, verify our quality standards certificates independently, sample product or check product reviews.

Additionally, we offer you warranty upon purchase should you experience any manufacturing defects.

Which Types Of RO Pumps Do RO Pump Manufacturers Offer?

We produce two types of RO pumps namely centrifugal pumps and positive displacement pumps.

Before you select reverse osmosis pump type, it is important to understand how they each work for best selection.

Centrifugal Pumps

Centrifugal pumps are also known as flow machine, a name derived from their operating principle.

Their operation is similar to that of water in a glass being stirred with a spoon.

This action pushes water upwards on the glass edges and a down in the middle creating a centrifugal force.

Centrifugal Reverse Osmosis (RO )Pump

 Centrifugal RO Pump

When the impeller is set in motion by drivers, it creates a force in the water as it accelerates.

The centrifugal force pushes water outwards to the edge of the impeller and through the output port.

As water is forced out, negative pressure is created inside the centrifugal pump forcing more water in and the process continues.

Centrifugal pumps are able to handle high water output due to their continuous motion and are therefore good for large operations.

Positive Displacement Pumps

Just like the name suggests, a positive displacement pump operates by displacing the water volume in the pump chamber.

A displacement body such as a piston moves into the closed space of the chamber, thereby reducing the space occupied by water.

This action forces the water out of the pump.

Conversely, when the piston moves out of the chambers, it creates negative pressure drawing in more water through the inlet.

The drawn water cannot flow back due to the presence of a blocking valve.

Positive displacement pumps are therefore referred to as volumetric pumps from their operating principle.

Postive Displacement Pump

 Positive Displacement Pump

Etching Technology

This branding technique uses strong acids or dyes to make design incisions in unprotected part of a metal. The level of cut on the metal surface depends on the strength of the acid and the period of contact.

This technique is common with 3 dimensional (3D) branding.

Back Injection

A special branding technique that allows us to use metal and plastic material to brand by special bonding material. It achieves a unique and sophisticated outcome on RO pump.

How Long Will RO Pump Manufacturers Take To Complete My Orders?

  • Pump kit which consist of pump head, feet, seal, driver holder, pump spares and net.
  • Water filter the membrane that water goes through.
  • Water purifier part
  • RO Unit that hold water that has gone through RO process.

How Does RO Pumps Work?

Reverse Osmosis pumps increase the pressure of water coming in from the source before channeling through RO unit. Household units mostly get their water from municipality and the pressure is usually below 45 PSI.

Since RO forces water through a membrane at high pressure, the pump therefore increases its pressure to 80 PSI or higher.

A typical RO pump consist of a transformer, pump and a pressure switch. When the transformer is plugged in power outlet, it converts voltage for the pump to use.

The pressure switch regulates the pressure by switching on and off.

Depending on the pump, the water let out of the RO pump is of higher pressure than water from inlet source.

How Long Will RO Pumps From China Last?

Our RO pumps can last a lifetime if you follow manufacturer’s instructions and offer regular service maintenance.

How Does Reverse Osmosis Pump Manufacturers From China Control Quality?

What Technology Do RO Pump Use?

RO pumps use reverse osmosis (RO) technology from where they derive their name.

Reverse Osmosis Expalined Diagrammatically

Reverse Osmosis Technology Explained Diagrammatically

Reverse osmosis is a process whereby contaminants are removed from water by forcing water through a semi-permeable membrane under high pressure.

The pump increases the water pressure coming in through the inlet thereby forcing water molecules through the semi-permeable membrane.

As a result, contaminants or salts are left behind and are referred as reject stream or brine.

The resulting water (product or permeate) is demineralized or deionized and has about 95% of contaminants removed from it.

Reject stream can either be feedback to the feeding water supply for recycling or drained out.

The amount of pressure required to force water through the semi-permeable membrane is directly proportional to the amount of contaminants. The higher the salt, the higher the water pressure needed.

Can RO Pump Manufacturer Offer Custom Options?

Yes, we do.

We have a team of experienced engineers who will assist you with the customs ordering process end-to-end. They will help convert your design idea into a mold then sample before actualizing it in production.

Do RO Pump From China Have Warranty?

We offer 12 months guarantee from the date of purchase against manufacturing defects and not normal wear and tear.

We have labor and parts warranty which cover service and part replacement respectively.

During warranty period you can return part(s) for repair or replacement and will shipping cost be shared between us.

For service maintenance we subcontract technicians who carry out door service during warranty period.

Our warranty is valid when you produce original copy of purchasing invoice or warranty card.

How Do RO Pump Manufacturers From China Ensure Voltage Compatibility?

Electricity voltage varies per region, therefore, we adhere to global standards per region to avoid compatibility issues.

For instance, RO pumps for the rest of the world will have between 220-240 volts and a frequency of 50 hertz. We ensure the sockets are also matching for easy connectivity.

Will RO Pump Manufacturers Protect My Designs?

Your RO pump design is your intellectual property right (IP) and should be protected from theft or violation. We can help protect your design in the following ways:

Sign Non-Disclosure (NDA) Agreement

A non-disclosure agreement is a legal document that bars us from exposing or leaking your design information to anyone. We can help you get an attorney here in China who understands how NDA work.

It is important that you include an attorney fee and injunctive relief clause in your contract to immediately stop design violation. This will not only stop design theft, but also provide attorney fee from the violator.

NDA agreements should be drafted in Chinese and English, with the Chinese one being the official document for use in China. It is easier for China courts to enforce a contract they can easily read and understand.

We as manufacturer sign NDA agreement with you before you share your design information with us.

Sign Chinese Enforceable NNN

Having a NDA contract is not enough when dealing IP, this is because there are loopholes that can work against you.

A Non-Use, Non-Disclosure and Non-Circumvention document that is China-centric is important.

A NNN protects you from competition with your own design, design leakage and non-circumvent situation.

A NNN should be drafted as per Chinese law, language and for use within Chinese court jurisdiction of your manufacturer.

We will sign a NNN before initiating business engagements with you and understand consequences in case of contract breach.

Register Trademark in China

Your design must be registered within China territory to protect it. In China, this happens in a ‘First-to- File Rule’ which simply implies first to file is the first owner.

You must do your due diligence by carrying out search to ensure that your design has not been registered in China.

We can help with this through our legal personnel, who will then provide you with a report of the search.

Once you are successful in your trademark registration, you can also register with China customs authority. This will bar any other manufacturer from manufacturing, supplying and exporting your design.

What Are The Benefits Of RO Pump?

  • Help eliminate bacteria, viruses, dissolved impurities and other disease causing germs making it safe and healthy for drinking.
  • It produces best quality water for hot drinks such as tea and coffee by removing solutes.
  • It removes chlorine, odor and metals such as lead and copper which impart metallic taste.

Are There Limitations Of RO Pumps?

  • Reverse osmosis pumps remove important minerals from water leaving it with acidic pH.
  • There is wastage of water that is flushed out after the purification process.

How Should You Maintain RO Pumps?

Maintenance of RO pumps should be done annually. We offer service maintenance free of charge during warranty period through a third party contractor.
