FAQ of WL38 DCB AC Solenoid Pump

1. What voltage is used by a micro solenoid pump?

The majority of micro solenoid pumps operate using DC voltage supplies such as 6, 12, or 24 volts. This is based on the design and requirements.

2. Is it possible for a micro solenoid pump to operate non-stop?

Yes. This is based on the duty cycle. Many micro solenoid pumps are designed to operate sporadically. If they are not designed for continuous use, they may overheat.

3. Can chemicals be handled by micro solenoid pumps?

Yes. This is based on the compatibility of the chemical with the diaphragm and seals. Before using the pump for this purpose, you should check the specifications.

4. How is the flow rate managed?

The voltage supply, pulse frequency, or a PWM controller may be used.

5. Can a micro solenoid pump be self-starting?

Yes. Many micro solenoid pumps are designed to be self-priming. This enables them to suck fluids within a specified height without any manual priming.

6. Why is there noise coming from my pump?

Due to the electromagnetic action, the pump may be making noise. However, excessive noise may be an indication of worn-out parts or high frequency and loose mounting.

How to Choose the Best Micro Solenoid Pump

For proper performance, long lifespan, and precise control of fluids, it is important to choose the appropriate micro solenoid pump. Here is a comprehensive guide for selecting the appropriate pump:

1. Determine the required flow rate—most important

Calculate the required amount of liquid you need to pump. This may be in milliliters/minute or liters/minute.

Think about the actual working conditions and not just the free flow rate. 👉 Crucial point:

It is important to test the pump under load because the rate at which the pump operates is reduced as the pressure increases.

For example, in a laboratory environment, the rate should be between 1 and 10 milliliters/minute.

Coffee maker—20-50 milliliters/minute

2. Examine the working pressure

Determine the system pressure in bar or psi.

The pump should be able to deliver the required pressure.

👉 Crucial point:

The working as well as the maximum operating pressure should be within safe limits. • Advice:

For standard micropumps—low operating pressure

For reinforced or industrial design—high operating pressure

3. Choose power & voltage

Common options—AC220V or DC—6V/12V/24V

It should be an exact fit for your power system. 👉 Incorrect voltage may lead to:

Imprecise or poor performance

Damage to the coil or overheating

✏ When choosing a pump for compatibility reasons, standard voltage is recommended.

4. Determine the type and compatibility of fluids

Find out what type of fluids you will be pumping—food grade, water, chemical, or oil.

Is the fluid thick, or does it corrode?

👉 Crucial point:

For example, water-plastic housing is okay

Chemicals—PTFE or stainless steel is required

5. Assess the duty cycle – mode of work

Periodic (ON/OFF cycles)

Continuous operation 👉 Crucial: If a pump is not designed to operate continuously, overheating may occur. Therefore, always ensure:

Duty cycle rating

Rise in coil temperature

6. Installation space and size

Check type of mounting:

Ported (direct tubing)

Foldable mount

👉 Small footprint pumps are required for compact devices, e.g., coffee makers and medical devices.

Also, ensure the type of connection and port size.

7. Precision & Control Method

PWM (pulse control for flow adjustment)

ON/OFF control ✏ To ensure precise dosing, ensure:

Choose pumps with high repeatability.

Constant frequency response

8. Requirements for noise and vibration

Crucial: Medical devices

Home appliances ✏ To ensure low noise, choose:

Minimal noise design

Mounting rubber

Operation with lower frequency

8. The surroundings

Check if the environment is suitable:

Operating temperature range

Exposure to water and humidity

Exposure to dust or vibration: Industrial – IP protection, etc.

Waterproof design: Outdoor use

10. Durability & Dependability

Check cycle life:

Millions of cycles, etc.

Review:

Durability of seal

Coil quality

✏ If pumps are not chosen properly, there may result:

Leakage

Flow instability

Early failure

Quick Selection Checklist: Required flow rate (ml/min); Working pressure (bar/psi); Voltage (6V, 12V, 24V, AC); Fluid type (water, chemical, oil, etc.); Duty cycle (continuous/intermittent); Size, type of installation; Noise requirement: Material compatibility; Lifespan requirement
