Best Sumbersible Pond Pump For You

From the gentle trickle of the smallest fountain to the heart-pounding roar of the largest waterfall, the success of any water feature is dependent upon the pump used in its construction. Many different types of pumps exist to help the pond enthusiast create the perfect effect. In this week's newsletter we'll take a little deeper look at the advantages and disadvantages of the 3 main types of submersible pumps:

 

Magnetic Drive Pumps

The magnetic drive pump contains an actual magnet at the core of its impeller assembly and spins in either direction. The motor is encapsulated in resin with the impeller as the only moving part.

Advantages:

The biggest benefit of magnetic drive pumps is their extremely low power consumption, lower relative price point, and small size. These pumps are designed for 24/7 operation making them a great choice for fountains and smaller ponds.  

Drawbacks:

With AC electricity the rotor changes directions each time power is applied to the magnetic drive pump. In addition, the shaft must be ceramic (not steel). This means these pumps can only effectively serve the lower end of GPH requirements (up to 2,000 GPH). Also, they should not be used in applications where the pump is going to be turned on and off frequently.

Direct Drive Pumps

Direct drive pumps have been the mainstay of the pond industry for many years. The pumps are characterized by a steel impeller shaft connected directly to the pump motor, with only the impeller emerging from the pump motor body.  

Advantages:

High flow capacity and capabilities of reaching higher waterfalls or features make the direct drive pump the continued choice by many pond enthusiasts. The direct drive nature of these pumps coupled with the impeller design allow for many solids to easily pass through without damaging the pump. Some direct drive pumps advertise the ability to pass up to 2˝ solids.

Drawbacks:

Higher energy consumption has long been a drawback of direct drive pumps. However, recent technological advances have greatly improved efficiency. In addition, mechanical seals can be weak point of direct drive pumps. If the seals leak water enters the electrical motor and the pump will short out and be ruined. Quality varies widely among the many direct drive pumps on the market and we can certainly help with determining the right pump for you.

Magnetic Hybrid Pumps

Unlike the magnetic drive pumps, which use an actual magnet, the hybrid only creates a magnetic field when the power is turned on. The impeller assembly is exposed to the water just like in the magnetic drive pump but in these pumps the rotor consists of a large steel or composite alloy (usually stainless steel) to which a curved vane impeller is attached allowing for higher pump output.  

Advantages:

The magnetic hybrid pumps are perfect for medium flow needs. They can push more water than magnetic drive pumps, but provide similar energy efficiency benefits. Also, they work well in applications where the pump will be turned on and off frequently.  

Drawbacks:

They cannot pass solids at all. Therefore, it is strongly recommended that the hybrid pumps be installed in a screened water environment to protect the pump from debris such as sand or grass clippings. You should always use either a pre-filter or a pump sock with hybrid pumps.
