DAB® EUROINOX 50/506 Multistage Centrifugal Pump with Mas Control — 115V/230V Dual Voltage / 1.36 hp

DAB® EUROINOX 50/506 Multistage Centrifugal Pump with Mas Control

The DAB® EUROINOX 50/506 is a high-performance stainless steel multistage centrifugal pump built for quiet, reliable water supply in hydroponic facilities, greenhouses, domestic pressurization systems, and irrigation applications. With a 115V/230V dual-voltage motor producing 1.36 hp (1 kW nominal), it delivers 1-32 GPM at heads up to 236 ft (102 psi), with a maximum operating pressure of 116 psi — providing the flow and pressure range needed for multi-zone irrigation manifolds and tall greenhouse structures.

The integrated Mas Control electronic safety device monitors for dry-running conditions and automatically protects the pump from damage when flow is interrupted — a critical safeguard in automated growing systems where sensor failures or reservoir low-water conditions could otherwise cause pump burnout. The stainless steel pump body and AISI 304 steel internal components deliver lasting corrosion resistance in demanding water supply environments. Horizontal fixed or portable installation flexibility suits both permanent pump room mounting and mobile grow facility configurations. Note: Replaces Leader Ecotronic 250 (#LDR60115861).

Key Features & Benefits

• Mas Control Dry-Run Protection — Electronic safety device automatically shuts down the pump when dry-running is detected, preventing motor burnout from reservoir low-water or empty-tank conditions.
• 115V/230V Dual Voltage — Single motor operates on either standard residential 115V or commercial 230V supply, providing installation flexibility across different electrical service configurations.
• Stainless Steel Body — AISI 304 steel pump body, shaft, and seal holder deliver long-term corrosion resistance in clean water supply applications.
• 1-32 GPM Operating Range — Wide flow range supports everything from low-demand drip irrigation to multi-zone distribution manifolds and pressure boosting applications.
• 116 psi Maximum Operating Pressure — Suitable for tall greenhouse structures, multi-floor facilities, and high-pressure irrigation heads requiring elevated system pressure.
• Quiet Multistage Design — Multistage centrifugal architecture provides smooth, low-noise operation compared to single-stage pumps at equivalent pressure.

Who Should Use This

Commercial greenhouse operators, indoor growing facility engineers, and irrigation system designers who need a reliable, dry-run-protected pressure pump for water supply and pressurization will find the EUROINOX 50/506 a proven, field-ready choice. It directly replaces Leader Ecotronic 250 installations and is well suited to facilities transitioning away from legacy pump equipment while maintaining performance specifications.

Frequently Asked Questions

How does the Mas Control system work?

Mas Control monitors pump operating parameters to detect dry-running conditions (insufficient liquid flow). When detected, it automatically stops the pump to prevent overheating and motor damage. The pump can be restarted once liquid supply is restored.

Does this pump require priming?

Multistage centrifugal pumps typically require priming on initial startup or after running dry. Follow DAB's priming instructions in the installation manual before first use.

Can this pump be used for nutrient solution recirculation?

The pump is rated for clean, chemically neutral liquids. Dilute nutrient solutions may be compatible — verify chemical compatibility with DAB based on your specific nutrient formulation and concentration before use.

Does the dual-voltage switch automatically, or do I need to configure it?

Dual-voltage motors typically require manual configuration (jumper or terminal reconnection) for the selected voltage. Consult the installation manual for the specific wiring procedure for your supply voltage before connecting power.
