Key Benefits

• Thermoplastic housing – durable, corrosion-resistant, and UV-resistant, ensuring long service life even in harsh weather conditions.
• Effective pre-filter with transparent cover – traps large debris (leaves, sand), protecting the filtration system from clogging. The transparent cover allows quick inspection of the basket without disassembly.
• Corrosion-resistant materials – AISI 316 stainless steel shaft (saltwater version) and heat-resistant housing allow operation with fresh and salt water, minimizing damage risk.
• Safety and motor protection – thermal overload protection, class F insulation, and IP55 rating ensure reliable operation in humid environments (up to 95% humidity).
• Self-priming design – after initial filling of the pre-filter, the pump self-primes from the installation, simplifying startup and eliminating the need for additional check valves.

Technical Specifications

The STP50M model is an optimal choice for garden pools up to 26,000 liters. The 6.5 m³/h flow rate enables effective circulation and compatibility with sand filters up to 400 mm diameter, as well as manual pool vacuums – providing adequate suction for debris collection from the pool floor.

The pump construction is based on durable, heat-resistant, and corrosion-resistant thermoplastics. With IP55 protection and thermal safeguards, the unit can operate in humid environments (up to 95% humidity) with liquid temperatures from +4°C to +50°C. The AISI 316 stainless steel shaft allows safe use with salt water, making it a versatile unit for various installations – from residential pools to mariculture systems.

The pump is self-priming – after initial filling of the pre-filter with water, it can self-prime from the installation even if located above the water level. However, installation below water level is recommended for optimal performance. To avoid performance loss and cavitation, use rigid PVC-U pipes with a diameter of 50 mm – this is the most common installation mistake.

Choose the Aquaviva LX STP50M pump and enjoy clean water all summer long. Covered by a 24-month manufacturer warranty – remember regular maintenance and replacement of consumables. During installation, an additional motor protection switch is required. Order today and ensure reliable circulation for your pool!
