Water purifiers, as important equipment to ensure the safety of drinking water in modern households, have complex and precise internal structures. Besides the core component, the filter cartridge, which is responsible for filtering impurities and purifying water, the pump for water purifier is also an indispensable key component. The pump for water purifier provides stable pressure driving, ensuring smooth water flow through the filter cartridge to complete the purification process.
Pump for water purifiers are mainly divided into two types: booster pumps and self-priming pumps. The booster pump for water purifier is mainly used to increase the water pressure to meet the stringent requirements of high-efficiency filtration technologies such as reverse osmosis. In high-rise residential buildings or situations with insufficient water pressure, the booster pump for water purifier can ensure that the water purifier operates normally.
On the other hand, self-priming pump for water purifiers are suitable for non-tap water sources such as well water or mountain springs. They can self-priming and pressurize, providing a stable water supply for the water purifier.
With prolonged use, pump for water purifiers may develop various faults, affecting the normal operation of the water purifier. Here are some common fault phenomena and solutions:
Abnormal Noise from the Pump for Water Purifier
If the pump makes abnormal noises during operation, it may be due to impurities attached to the diaphragm. At this point, try performing a backwash or disassemble the pump head for cleaning. If a wheezing sound is heard, it may be due to excessively high inlet pressure; it is recommended to install a pressure reducing valve or adjust the position of the inlet solenoid valve.
Voltage is Normal but the Water Purifier Does Not Work
If the voltage is stable and meets the water purifier's requirements, but the purifier still does not work, the pump may be faulty. In this case, try short-circuiting the low-pressure switch for testing. If the pump still does not respond, a new pump needs to be replaced.
Reduced Water Production and Increased Wastewater
If the water purifier's water production decreases and wastewater increases, and the pump makes noise but can normally shut down, first check if the filter cartridge is clogged. If the filter cartridge is normal, then the inlet solenoid valve or pump may be clogged. In this case, try closing the pressure tank, blocking the wastewater pipe, and turning on the faucet for testing. If the water flow increases, the problem lies at the inlet end.
