HMD410/110R: Main Drain 410 x 410 with 110mm Connections

Product Overview

As a retailer of hot tub and pool spare parts, I’m excited to present the HMD410/110R, a high-capacity main drain designed for efficient water circulation and enhanced safety in larger swimming pools. This substantial 410 x 410 mm drain with 110mm connections is engineered to meet strict safety standards while providing superior flow rates for your pool system.

Key Features

Advanced Safety Design

The HMD410/110R is designed with swimmer safety as the top priority:

1. Anti-Entrapment Technology: Engineered to significantly reduce the risk of suction entrapment.
2. Dual Drain Compliance: Meets regulations requiring a minimum of two main drains installed at least 2 meters apart.
3. Large Surface Area: The 410 x 410 mm size distributes suction over a much wider area, further enhancing safety.

High-Capacity Water Circulation

This main drain offers two flow rate options to suit large pool sizes and demanding pump systems:

1. 33m³/hr at 0.3m/s velocity – Ideal for standard operations in larger pools
2. 55m³/hr at 0.5m/s velocity – Maximum allowable velocity for high-demand systems

Professional-Grade 110mm Connections

Equipped with 110mm connections, the HMD410/110R ensures:

1. Compatibility with standard pool plumbing systems
2. Efficient high-volume water flow from the pool to the filtration system
3. Easy integration with existing pool setups or new installations

Durable Construction

Manufactured using high-quality, chemical-resistant materials, this main drain is built to withstand:

1. Constant water exposure
2. Pool chemicals
3. UV radiation
4. High water pressure from increased flow rates

Installation and Compatibility

The HMD410/110R is designed for professional installation in large in-ground swimming pools. Its larger size and 110mm connections make it ideal for new pool constructions or renovations of existing large pools requiring enhanced water circulation.

Why Choose the HMD410/110R?

Opting for the HMD410/110R means investing in:

Safety and Regulatory Compliance

It’s crucial to emphasize that regulations require a minimum of two main drains to be installed at least 2 meters apart, even for these larger units. This requirement is designed to prevent a single-point suction hazard, significantly enhancing swimmer safety. Always ensure your pool design and installation comply with local and national safety standards, especially for high-capacity systems.

Maintenance Recommendations

To ensure the longevity and optimal performance of your HMD410/110R main drain:

1. Conduct regular inspections for any debris accumulation or damage
2. Clean gently with appropriate pool cleaning tools and solutions
3. Check for proper water flow periodically, especially given the high-capacity nature of this drain
4. Ensure the drain cover is securely in place at all times
5. Schedule professional inspections of the entire drainage system annually

Proper maintenance of your HMD410/110R not only extends its lifespan but also ensures the safety and efficiency of your pool’s high-capacity circulation system.

Ideal Applications

The HMD410/110R is perfect for:

• Large in-ground pool constructions requiring high water turnover rates
• Commercial pools or aquatic facilities with demanding circulation needs
• Renovation of large pools to improve water quality and circulation
• Pools with 110mm plumbing systems requiring a high-capacity main drain

The HMD410/110R main drain represents a crucial component in large-scale pool circulation and safety systems. Its design balances the need for high-volume water flow with the paramount concern of swimmer safety. By choosing this main drain, you’re investing in a product that meets stringent safety standards while providing the performance needed for crystal-clear, well-circulated water in larger pool environments.

Remember, proper installation by a qualified professional is key to ensuring the safety and effectiveness of your main drain system, especially for high-capacity units like the HMD410/110R. Always consult with a certified pool technician or engineer when planning your pool’s drainage system, particularly when dealing with the specific requirements of large pools and high-volume water circulation.
