Frequently Asked Questions

1. What is the Atlantic MD350 TidalWave MD-Series Pump?

The Atlantic MD350 TidalWave MD-Series Pump is a compact magnetic-drive pond pump designed for dependable water circulation in small ponds, fountains, and decorative water features. With a maximum flow rate of 370 gallons per hour (GPH), it is suitable for low-head applications that require reliable water movement and energy-efficient operation.

2. What is the maximum flow rate of the Atlantic MD350 Pond Pump?

The Atlantic MD350 has a maximum flow rate of 370 GPH under low-head conditions. The actual water flow decreases as pumping height and plumbing resistance increase. Consider your installation's total dynamic head when choosing this pump for a pond, fountain, or water feature.

3. How much water does the Atlantic MD350 pump at different heights?

According to the manufacturer's MD-Series performance chart, the Atlantic MD350 delivers approximately 145 GPH at 5 feet of head. Water flow decreases as the pumping height and plumbing resistance increase, so account for vertical lift, pipe length, and fittings when planning your installation.

4. Is the Atlantic MD350 suitable for small pond fountains and waterfalls?

Yes. The Atlantic MD350 TidalWave Pump can be used for appropriately sized small fountains, gentle waterfalls, and decorative water features. Because its flow rate is relatively low at increased pumping heights, check the required water flow and total dynamic head before selecting it for your project.

5. Can the Atlantic MD350 be used for pond filtration?

The Atlantic MD350 can circulate water through a compatible small pond filtration system when the required flow falls within the pump's operating range. Choose a filter that matches your pond's needs and the pump's available flow. Clean the removable pre-filter regularly to help maintain consistent circulation.

6. What type of pump is the Atlantic MD350?

The Atlantic MD350 is a magnetic-drive, or Mag Drive, pump. It is designed for low-head water circulation in small ponds, fountains, and water features. The MD-Series features a serviceable impeller assembly, a removable pre-filter, and an oversized ceramic shaft designed to help reduce internal wear.

7. How much electricity does the Atlantic MD350 use?

The Atlantic MD350 operates on a 115-volt power supply and consumes 25 watts according to the manufacturer's specifications. Actual electricity use depends on operating conditions and running time. Follow the manufacturer's electrical safety instructions and use a properly grounded, GFCI-protected outlet for pond equipment.

8. What size inlet and outlet connections does the Atlantic MD350 have?

The Atlantic MD350 features a 1-inch MIPT inlet and a 3/4-inch MIPT outlet. It includes a stepped outlet fitting designed to accommodate compatible tubing sizes. Confirm the fitting type and tubing diameter before installation to help ensure a secure connection and suitable water flow.

9. Does the Atlantic MD350 include a removable pre-filter?

Yes. The Atlantic MD350 includes a removable pre-filter that helps prevent debris from entering the pump. The pre-filter provides additional intake surface area and can help reduce maintenance. Disconnect the pump from the power supply before cleaning the pre-filter or servicing the pump.

10. What is the maximum head height of the Atlantic MD350 Pond Pump?

The Atlantic MD350 has a published maximum head height of approximately 7 feet. Its flow rate decreases significantly as the pumping height increases, with approximately 145 GPH listed at 5 feet of head. For best results, consult the manufacturer's performance chart and account for plumbing restrictions when calculating total dynamic head.

11. What are the dimensions and power cord length of the Atlantic MD350?

The Atlantic MD350 measures approximately 4.5 inches long, 3.5 inches wide, and 5 inches high. It includes a 20-foot power cord, offering flexibility for suitable pond and water-feature installations. Allow enough room for plumbing connections, cleaning, and routine maintenance.
