What Are the Common Faults of RO Pumps? How to Solve Them?

RO pump is one of the important components of a water purifier and is known as the "heart" of the water purifier. However, as time goes by, the RO pump may encounter some problems.

Do we really need an RO pump in a water purifier?

Nowadays, people are becoming more and more aware of water pollution and are pursuing high-quality drinking water. In terms of ensuring the safety and hygiene of daily drinking water, water purifiers are undoubtedly the first choice for many families. However, many people may wonder if an RO pump is necessary for a water purifier.

Before answering this question, let's first understand what an RO pump is. An RO pump, also known as a water purifier pump, is an important device that provides power for a water purifier.

As the name suggests, the RO pump is closely related to the RO membrane. Because the filtering aperture of the RO membrane is very small, about 0.0001 microns, the original water cannot pass through the RO membrane simply by relying on the water pressure itself, which will lead to unsatisfactory filtration effect and may cause malfunctions of the water purifier. The RO pump can provide higher pressure so that water can flow smoothly inside the machine.

Therefore, the reverse osmosis water pump is designed specifically for water purifiers that use reverse osmosis membranes. Various types of household water purifiers, commercial direct drinking machines, pure water machines and other products that are widely popular with users on the market nowadays all need to install appropriate RO pumps to work normally.

In general, RO pumps are standard configurations for reverse osmosis water purifiers, and users usually do not need to purchase them separately. However, if there are any problems, consumers will certainly feel headache. Therefore, water purifier manufacturers must choose high-quality water pumps.

There are several common problems with RO pumps :

1. Pump head leakage: This is mostly caused by the diaphragm being ruptured or deformed due to the pump working for too long or under too much pressure.

2. Abnormal noise: This may be due to the rotation parts being loosen due to the long working time or excessive working pressure of the pump; uneven workloads caused by unstable water inlet pressure, or the base fixing screws not being tightened during installation.

3. Low boosting pressure (working flow rate): This could be due to low water inlet pressure, air entering the pump boosting chamber, or unreasonable waste water ratio.

4. High working current: This is mainly caused by the overload pressure of the pump, clogging of the RO membrane, or the rotor of the motor being locked.

If RO pump encounters problems, it will affect the normal operation and safety of the whole machine. Therefore, we need to perform self-inspection on the machine and treat the problem accordingly.

In addition, we can also prevent problems from happening by choosing water pump products with lower failure rates.
