Pond Pumps in Australia
Considerations
From the smallest barrel to the largest pond, no water garden can
survive very long without water movement. And for water movement,
a pond pump is essential because it keeps the water circulating
and the pond/water garden healthy.
A cascading, bubbling stream adds interest and serenity to the
garden, while a waterfall can create a dramatic centre piece. Fountains,
are aesthetically pleasing and provide the additional benefit of
aerating the water, essential for providing a healthy environment
for fish.
When selecting a pond pump, be sure to consider:
- litres per hour (LPH) of each pond pump
- maximum height that the unit will pump (known as head height)
- type of pond filter
- manufacturer's warranty
- power consumption
You get what you pay for and its advisable not to cut corners when
choosing your pond pump - it may well cost you time and money to
fix in the long run, as ponds can quickly become a green smelly
mess if the correct equipment is not used.
Calculating the litres per hour
To determine the litres per hour rate for your pond pump, there
are a number of factors that must be taken into account to pick
the right equipment.
- The actual volume of your pond
- The 'effective volume' (taking into account - Fish, pond depth
& size, sunshine, climate etc
- The maximum pumping height (head ) - taking into account elbows,
tees, friction loss, hose size
- Waterfalls & streams, tube friction loss (see chart below)
- The weir rate for waterfalls and streams
- Pond filter (if being used) see 'Filters' below
- Power consumption (watch the watts)
