WATER PUMP SELECTION MADE EASY BY WALRUS PUMP Co.Ltd
A water walrus pumps of the type we will discuss is used extensively in all types of water features. Such a water pump is referred to as a centrifugal water pump … quite simply this means the pumps has an impellor that spins around and use centrifugal force to deliver water. They are hard to damage because even if the outlet (discharge) from the water pump becomes blocked no damage occurs. In this way flow control is made easy by restricting the outlet pipe using a valve or even by clamping the pipe partly shut.
Using a water pump in ponds means using a submersible water pump in something like 99% of all circumstances … the pump would normally lie just off the bottom of the pond, completely submersed. Because they are submersed the height a water pump needs to pump against is measured from the water surface and not from the bottom of the pond. This height is normally referred to as ‘head’ in water pump jargon.
Think of a water pump as being able to provide a fixed amount of energy to circulating water. Think of this constant energy derived from the electric motor as being shared out in 2 ways…. water pump energy in part 1 is used to pump volume and the water pump energy part 2 is used to lift that volume. If you give larger share of this energy to volume then the lift has to be less.
Here’s a simple analogy… You would need the same energy if you carried one bucket of water up a flight of stairs 20 feet high as you would if you carried 2 buckets of water up a flight of stairs 10 feet high. A water pump is just like this … if you want to pump more volume higher then get a bigger pump. One size cannot fit all situations for the simple reason the energy from the pump motor is constant in most cases.
You will now understand that to specify and buy a water pump that will do a good job it is necessary to know how much water is to be pumped and how high that volume of water must be pumped. Without both bits of information you cannot specify a water pump accurately.
