Product Overview
The Atlantic Water Gardens MD-Series magnetic induction pumps are engineered for optimal performance in small water features and fountains, particularly those with low head heights. These submersible pumps are constructed for durability and energy efficiency, featuring a robust design suitable for demanding conditions.
Key components include removable pre-filters for easy cleaning, oversized ceramic shafts for extended wear resistance, and replaceable impeller assemblies to ensure long-term operation. Each pump is equipped with a 20-foot power cord for flexible placement and comes with a five-year limited warranty, reflecting its quality and reliability.
MD-Series pumps are also compatible with TidalWave Fountain Heads, allowing for enhanced aesthetic possibilities in your water garden. Understanding the pump's capabilities, especially its Total Dynamic Head (TDH), is crucial for selecting the correct model for your specific pond, waterfall, or fountain application.
Features

Setup and Installation
Proper setup is essential for the optimal performance and longevity of your Atlantic MD250 pump. Follow these general guidelines for installation:
- Placement: Position the submersible pump at the lowest point in your water feature or fountain basin, ensuring it is fully submerged in clean water.
- Tubing Connection: Connect appropriate tubing to the pump's male threaded outlet. The rotatable volute allows for flexible tubing routing. Ensure all connections are secure to prevent leaks and maintain optimal flow.
- Pre-filter Installation: Ensure the removable pre-filter is securely attached to the pump's inlet. This filter protects the impeller from debris.
- Electrical Connection: Route the 20-foot power cord safely to a grounded electrical outlet. Avoid kinks or damage to the cord. Ensure the outlet is protected by a Ground Fault Circuit Interrupter (GFCI) for safety.
- Initial Priming: As a submersible pump, it will self-prime once submerged and powered on. Ensure the pump is completely underwater before activating.

Operating Instructions
The MD250 pump is designed for continuous operation in water features and fountains. Once properly installed and submerged, simply plug the pump into a grounded GFCI-protected outlet to begin operation. The pump will immediately start circulating water.
For optimal performance and energy efficiency, ensure the water level in your feature remains adequate to keep the pump fully submerged. Running the pump dry can cause damage and void the warranty.
The MD250 is specifically suited for small water features and fountains with low head heights. For applications requiring higher flow rates or greater vertical lift, refer to the pump selection guide to ensure the correct model is used.

Maintenance
- Pre-filter Cleaning: Periodically remove and clean the pre-filter to prevent clogging and maintain optimal water flow. The frequency depends on the amount of debris in your water feature.
- Impeller Inspection: If flow decreases or the pump becomes noisy, inspect the impeller assembly for debris or wear. The impeller can be accessed with a quarter-turn of the volute and is replaceable.
- Shaft Inspection: Check the oversized ceramic shaft for any signs of wear or damage during impeller inspection.
- Winterization: In freezing climates, remove the pump from the water feature before the first hard freeze. Clean the pump thoroughly and store it in a frost-free location, submerged in a bucket of water to keep seals moist.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not run. | No power to pump; GFCI tripped; Impeller jammed. | Check power connection and GFCI; Clear any debris from impeller. |
| Low water flow. | Clogged pre-filter; Kinked or obstructed tubing; Worn impeller. | Clean pre-filter; Check and clear tubing; Inspect/replace impeller. |
| Pump is noisy. | Debris in impeller; Pump running dry; Worn bearings. | Clean impeller; Ensure pump is fully submerged; Contact support if noise persists. |
