In the increasingly competitive coffee machine market, product differentiation, reliability and user experience have become the key to success. As the "heart" of a coffee machine, the performance of the micro water pump directly determines the stability of extraction, the lifespan of the machine and user satisfaction.The limitation of leakage prevention, noise and space occupancy of traditional pump body is often a problem that puzzles R&D engineers.

According to these weaknesses, we recommend the PYSP370 - XJZ micro leak-stopping diaphragm water pump, it with its performance and reliable sealing technology, accurate parameters for a new generation of the coffee machine design provides the ideal solution.

I. Core Parameter Analysis: Why Is It Suitable for Coffee Machines?

The parameter specifications of this water pump are specially designed for small-sized and high-efficiency electrical applications, and are highly compatible with the requirements of coffee machines

Parameter Performance Indicators & Value to the coffee machine system

 

Parameter	erformance indicators	Value to the coffee machine system
Rate Voltage	DC 3V - 24V	The wide voltage design makes it easy to integrate into various DC power supply systems. Whether it is a household plug-in or a portable lithium battery-powered model, a matching solution can be found.
Power	Constant 3.6W	Low power consumption operation, reduce the heat of the whole machine, improve energy efficiency, the pursuit of energy saving and environmental protection of modern home appliances is very important.
Max water Pressure	>30 PSI (200kPa)	Provide a stable output pressure to ensure the basic pressure required for espresso extraction and ensure the full production of oil (Crema).
Water flow	0.5 - 1.2 LPM	The flow rate is precisely controllable, which can not only meet the needs of rapid water injection, but also cooperate with advanced processes such as pulse extraction to achieve precise control of flavor.
Head	>5m	The powerful head ensures that even if the water pump is installed at the bottom of the machine, it can effectively lift water from the water tank to the high-temperature boiler or brewing head at a higher position, making the layout more flexible.
Noise level	<65dB (30cm away)	Low-noise operation greatly enhances the user experience and is especially suitable for use in quiet environments such as homes and offices in the early morning or at night.
Life time	>500hours (continue)	Ultra-long life means lower failure rates and after-sales costs, providing reliable service for up to several years based on 10 uses per day.
Weight and volume	60g，Compact structure	The extremely light weight and miniaturized design provide great convenience for the precious space layout inside the coffee machine, facilitating the miniaturization of the product.

 

Ii. Core Advantage: The engineering significance of the "Micro Leak Stop" design

"Micro leakage stop" is not only the name of the product, but also the embodiment of its core competitiveness:

1.High reliability, eliminating leakage risk

By adopting a precise diaphragm structure and sealing technology, it physically isolates the liquid from the motor part, fundamentally avoiding the leakage problem caused by shaft seal wear in traditional water pumps. This is a crucial safety guarantee for coffee machines that are filled with circuit boards and control components inside.

2. Dry running self-priming capacity

With a suction lift of over 2m, it has excellent self-priming ability. Even when there is a small amount of air in the pipeline or the water pump runs dry for a short time, it can quickly resume operation and will not be easily bound by air like some centrifugal pumps, enhancing the stability and durability of the system.

3. Convenient maintenance, high cleanliness

diaphragm pump working principle of the passage is relatively simple, not easy to shelter evil people and practices, to facilitate the coffee machine automatic washing and maintenance, to ensure that the waterways clean sanitation.

Iii. Typical Application Scenarios in Coffee Machine Systems

Main extraction system: provides stable and pulsed extraction pressure for espresso machine.

Quantitative water injection system: In drip or capsule coffee machines, it achieves precise water volume control.

Water tank pressurization and transportation: solve the water supply problem of the lower water tank or external water source.

Automatic cleaning cycle: As a cleaning pump, drive cleaning liquid or clean water cycle to wash the brewing system and pipeline.
