LITTLE GIANT POND PUMP OVERVIEW
Choosing a Little Giant pond pump - Little Giant PondWorks is a respected manufacturer of pumps, liners, filters, pond decor, and pond maintenance-related products. This page will deal with their line of pumps, which come in a number of different types and sizes, able to satisfy needs ranging from small fountains to larger-sized ponds.
Types of Pumps Available
Little Giant makes two different kinds of pumps that are sold into the pond market. The first is direct drive pumps and the second is magnetic drive pumps. Read on to learn about the differences between these two popular styles.
Direct Drive Pumps
The direct drive system is the traditional method of building a pond pump. An electric motor is used to turn a drive shaft, which is connected to an impeller, drawing water through the pump. As the motor turns, the impeller rotates at the same rate due to the direct connection between them. Because electric motors and water do not mix well, the motor is typically encased inside a motor housing. To keep water out, there is usually a drive shaft seal where the shaft exits the housing. Additionally, the motor housing is often filled with a type of oil to further prevent water ingress. If the shaft seal ever fails, water can leak in, effectively destroying the electric motor. Concurrently, oil usually leaks out into the water, creating a miniature oil spill. However, these issues can generally be prevented by choosing a reputable brand like Little Giant and performing regular checks and maintenance. To minimize any ecological damage in the event of a leak, Little Giant uses a non-toxic dielectric oil, which is very similar to mineral oil.
Direct Drive Pumps
Magnetic Drive Pumps
Magnetic drive pumps are a newer technology that uses magnets to turn the impeller. Instead of the motor turning a drive shaft as in a direct drive pump, the motor turns a strong magnet inside the motor housing. In a separate, but adjacent chamber, a second magnet is attached to the impeller. As the electric motor turns the first magnet, the strength of the magnetic bond causes the second magnet to turn as well, resulting in the rotation of the impeller. The advantage of magnetic drive over the direct drive system is that the motor can be fully encased inside the motor housing with a limited chance of water entering the housing or oil leaking into the pond due to faulty seals.
