Atlantic MD-Series Pumps
Magnetic Induction Pumps for Demanding Applications
Atlantic's MD-Series Pumps provide years of service under the demanding conditions of smaller ponds, waterfalls, and fountains through advanced magnetic induction technology. Engineered with better flows at higher heads, a longer warranty, and easier serviceability than conventional pumps, the MD-Series delivers professional-grade performance with features that extend pump life and simplify maintenance.
Superior Design Features
Male threads on both inlet and outlet are less restrictive for higher flow, while the volute can be oriented in four ways for maximum versatility in placement. A quarter-turn accesses the replaceable impeller assembly for easy periodic cleaning, and the removable pre-filter with oversized ceramic shaft reduces internal wear and extends service life. The large, stable base anchors the pump securely and may be removed in tight applications.

Applications
Ideal for small to medium ponds, waterfalls, fountains, pondless waterfalls, streams, and water features requiring reliable flow at varying heights. Perfect for installations where serviceability, longevity, and performance at higher heads are critical.
Why Magnetic Induction?
Magnetic induction pumps use magnetic coupling to drive the impeller, eliminating direct mechanical connection between motor and impeller. This design reduces wear, improves efficiency, and extends service life compared to conventional direct-drive pumps. The result is a pump that runs cooler, quieter, and longer while delivering consistent performance year after year.
Frequently Asked Questions
Q: Which MD-Series pump do I need?
A: Choose based on your required flow rate (GPH) and head height. Smaller models (MD250-MD750) suit compact installations, while larger models (MD1000-MD1500) handle higher flows and greater heights.
Q: What does "better flow at higher heads" mean?
A: "Head" is the vertical distance water must be pumped. MD-Series pumps maintain stronger flow rates at greater heights compared to conventional pumps of similar size.
Q: How do I clean the impeller?
A: Simply turn the volute a quarter-turn to access the impeller assembly. Remove it, rinse under water to remove debris, and reinstall. This periodic cleaning maintains optimal performance.
Q: Can I orient the pump outlet in different directions?
A: Yes, the volute can be oriented in four ways, allowing you to position the outlet in the direction that best suits your installation.
Q: What are the 1.5" adapters for?
A: The MD1000, MD1250, and MD1500 include 1.5" adapters for compatibility with Atlantic's Triton Check Valve and Fountain Plumbing Kits.
Q: Can I remove the base?
A: Yes, the large stable base can be removed for installations in tight spaces where the base footprint is too large.
Q: How often should I clean the pre-filter?
A: Check the pre-filter monthly during heavy use and clean as needed. Regular pre-filter maintenance protects the impeller and maintains flow rates.
Q: What is the ceramic shaft?
A: The oversized ceramic shaft is the component that supports the impeller. Ceramic is extremely hard and wear-resistant, extending pump life by reducing internal wear.
Q: Are these pumps submersible?
A: Yes, MD-Series pumps are designed for submersible operation in ponds, fountains, and water features.
Q: What warranty do MD-Series pumps have?
A: MD-Series pumps feature an extended warranty longer than conventional pumps. Consult your warranty documentation for specific terms and coverage details.
