Self-Draining Housing—Why It Matters:
The integrated self-draining housing is a critical hygiene feature that sets this pump apart:
Complete Water Evacuation:
After each spa use, the self-draining design ensures complete water drainage from the pump housing. Simply loosen the front union, and water drains completely. This prevents stagnant water from sitting in the pump between uses—a breeding ground for bacteria and algae.

Frequently Asked Questions (FAQs)
1. Can this pump be used in hot spas?
Absolutely! The BADU 45/20 is temperature stable up to 60°C (140°F), making it perfect for hot spa applications. The robust materials and thermal-resistant design ensure consistent, reliable performance even with continuous hot water exposure and demanding use.
2. Is this pump easy to install?
Yes! Installation is straightforward:
- Standard 50mm union fittings connect to most spa plumbing
- Compact design fits tight spaces easily
- Simple electrical connection to 230V single-phase power
- Self-draining design eliminates complex drainage setup
For safety and warranty validity, professional installation is recommended, but the design makes installation accessible.
3. Does this pump require frequent maintenance?
Minimal maintenance is required:
Regular (Weekly):
- Check for leaks
- Verify circulation
- Drain pump housing after use
Periodic (Monthly/Annually):
- Clean inlet strainer if equipped
- Inspect electrical connections
- Check for mineral buildup
The self-draining feature reduces water stagnation, enhancing longevity and hygiene compared to pumps that retain standing water.
4. What’s the main benefit over the BADU 45/16?
The BADU 45/20 offers significant advantages:
- More Power: 1.1kW vs. 0.75kW (47% more output)
- Better Jets: Powerful, responsive jet performance
- Faster Heating: Superior water circulation accelerates heating
- Premium Experience: Luxury spa performance
- Same Compact Size: No increase in footprint
Choose the 45/20 if you want high-performance spa experience or have demanding applications.
5. What’s the self-draining housing and why is it important?
The integrated self-draining housing automatically evacuates water from the pump after each use. Simply loosen the front union, and water drains completely. This is crucial because:
- Hygiene: Prevents stagnant water from harboring bacteria and algae
- Safety: Eliminates standing water that could harbor harmful microorganisms
- Protection: Prevents freeze damage and mineral buildup
- Maintenance: Makes the pump easier to inspect and service
This feature is a hallmark of quality spa pumps and sets SPECK apart from budget alternatives.
6. What’s the difference between power input (P1) and power output (P2)?
- Power Input (P1) = 1.50kW: Total electrical power the pump draws from your circuit
- Power Output (P2) = 1.1kW: Actual useful work the pump delivers to circulate water
The difference is lost as heat during motor operation—this is normal and expected. The 1.1kW output is what matters for your spa’s circulation performance.
7. Is this pump energy efficient?
Yes! The BADU 45/20 is designed for efficient operation:
- Optimized motor design minimizes energy waste
- 1.1kW output is appropriate for high-performance spas (not oversized)
- Efficient circulation reduces heating time and energy consumption
- Proper sizing ensures you’re not paying for unnecessary power
Compared to undersized pumps that can’t deliver adequate performance, the 45/20 provides excellent value.
8. Can I use this pump for pool circulation?
No. The BADU 45/20 is specifically designed for spa applications. For pool circulation, you need a pool pump (like the SPECK BADU PORPOISE series). Spa pumps and pool pumps have different design requirements and aren’t interchangeable.
9. What’s the warranty coverage?
The 36-month ex-factory warranty covers defects in materials and workmanship under normal operating conditions. It includes the motor, pump housing, and internal components. The warranty does NOT cover installation labor, damage from improper use, or wear items like seals. Warranty is valid only if the pump is installed according to manufacturer’s instructions.
10. How quiet is this pump?
The BADU 45/20 features reduced vibration design for quiet operation despite its powerful 1.1kW output. While no pump is completely silent, you’ll notice significantly less noise than standard or budget spa pumps. The quiet operation contributes to a more peaceful, luxurious spa experience.
11. What electrical requirements do I need?
The BADU 45/20 requires:
- Voltage: 230V single-phase (standard household power)
- Current: 6.3A
- Circuit: Dedicated 10-amp breaker minimum
- Grounding: Proper electrical grounding required
- GFCI: Ground fault circuit interrupter outlet recommended for safety
For safety and code compliance, have a qualified electrician handle the electrical connection.
12. Can I run this pump continuously?
Yes, the BADU 45/20 is designed for continuous operation in spa systems. However, most spa owners
