Should I Choose A Micro DC Or Micro AC Water Pump for My Dishwasher?

According to data from a domestic authority, dishwasher retail sales reached 900 million yuan in January 2022, a year-on-year increase of 27.3%. Offline dishwasher retail sales reached 200 million yuan, a year-on-year increase of 12.9%. This data shows that dishwashers have gradually become commonplace in most households and have become an indispensable household appliance.

The world's first dishwasher was invented by female inventor Josephine Cochrane in Shelbyville, Illinois. She received patent number 355139 on December 28, 1886. This dishwasher was exhibited at the 1893 Chicago World's Fair, and Josephine Cochrane later founded her own dishwasher company.

The advent of dishwashers has greatly reduced the burden of kitchen work, completely freeing up hands, reducing daily family friction, and promoting family harmony. Now, whether in a restaurant or at home, dishwashing has become more convenient and efficient, bringing cleanliness, hygiene, and ease to people.

Have you noticed that dishwashers rely on a spray nozzle to clean dishes? The water from the spray nozzle washes dishes because the dishwasher is equipped with a Shenpeng dishwasher pump. The high-pressure cleaning force of the 370 micro Diaphragm water pump rinses away grease and food residue from dishes, thereby cleaning both the dishes and chopsticks.

Currently, there are two types of dishwasher pumps: micro DC brush pumps and micro AC pumps. Which is better?

Micro AC pumps are small pumps powered by AC power. They operate on 220V AC power and use a 50Hz frequency commutation, resulting in very low speeds. AC pumps lack electronic components and can withstand high temperatures.

Pros and Cons of Micro AC Pumps:

Pros: Inexpensive and widely available.

Cons: Large, noisy, heavy, difficult to carry, require a high level of protection, and can cause electric shock if used improperly.

Micro dc water pump use a DC power supply to drive a brushless motor. Powered by a 4.5V to 24V DC power supply, the micro DC water pump utilizes electronic commutation, eliminating the need for carbon brushes. It also features a high-performance, wear-resistant ceramic shaft and sleeve. This significantly reduces wear, significantly extending the lifespan of the brushless DC magnetic pump.

Pros and Cons of Micro DC Water Pumps:

Pros: Long lifespan, noise level below 35dB, high precision, and excellent vibration resistance.

Cons: High price.

Currently, most dishwashers use AC water pumps. However, as people's living standards improve, their demands for higher quality home appliances are becoming increasingly stringent. Shenpeng DC water pumps are expected to gradually replace AC pumps, as the drawbacks of AC pumps are precisely aligned with people's demands for a better quality of life.
