Hailea HAP-100 Air Pump Replacement Diaphragm Twin Pack

Restore the performance of your Hailea HAP-100 air pump with this genuine replacement diaphragm twin pack.

Over time, the rubber diaphragms inside a linear air pump can stretch, harden or tear. This may lead to reduced airflow, lower pressure, extra noise or poor pump performance.

Replacing both diaphragms at the same time can help return the pump to proper operation without replacing the complete unit.

Genuine Replacement Parts for Hailea HAP-100

These diaphragms are designed for the Hailea HAP-100 linear air pump.

The HAP-100 is a high-output air pump rated at approximately 100 litres per minute, so maintaining healthy diaphragms is important for reliable airflow and pressure.

Worn diaphragms can reduce the amount of air delivered by the pump and place additional strain on the internal components.

Signs Your HAP-100 Diaphragms May Need Replacing

Replacement may be required if you notice:

• Reduced airflow
• Lower air pressure
• Increased pump noise
• Uneven air output
• Pump vibration
• Poor performance compared with when the pump was new

These symptoms can have several causes, but worn diaphragms are a common maintenance item in linear air pumps.

Why Replace Both Diaphragms?

The Hailea HAP-100 uses two diaphragms.

Replacing both at the same time helps keep the pump balanced and avoids leaving one older diaphragm operating alongside a new one.

This can help maintain more consistent internal movement and airflow.

Easy Maintenance Option

Replacing diaphragms is a much more economical option than replacing the entire HAP-100 when the pump itself is still in good working condition.

Basic tools are generally required to open the pump housing and access the diaphragm assemblies.

Always disconnect the pump from power before carrying out maintenance.

If you are unsure about servicing electrical equipment, have the pump inspected by a suitably experienced person.

Product Specifications

Frequently Asked Questions

What air pump do these diaphragms fit?

They are designed specifically for the Hailea HAP-100 linear air pump.

How many diaphragms are included?

The pack contains two replacement diaphragms.

Are these genuine Hailea parts?

Yes. They are genuine Hailea replacement diaphragms.

When should I replace HAP-100 diaphragms?

Replacement may be needed when airflow drops, pressure decreases, the pump becomes noisier or the existing diaphragms show signs of wear.

Should I replace both diaphragms at once?

Yes. Replacing both together is generally the better maintenance approach because both have usually experienced similar operating hours.

Will new diaphragms make my air pump quieter?

If increased noise is being caused by worn or damaged diaphragms, replacement may reduce noise and restore smoother operation.

Can replacing the diaphragms restore airflow?

Yes. Worn diaphragms can significantly reduce pump output, so fitting new diaphragms can help restore normal airflow when they are the cause of the problem.

Are these suitable for other Hailea HAP models?

No. Use the diaphragm kit specifically designed for your pump model. HAP-60, HAP-80 and HAP-120 pumps use different diaphragm sizes.

Do I need to replace the complete HAP-100 if the diaphragms wear out?

Not necessarily. If the rest of the pump is operating correctly, replacing worn diaphragms can be a much more economical repair.

Should I disconnect the pump before servicing?

Yes. Always disconnect the air pump from mains power before opening or servicing it.
