Note on Pumps
for filtration of koi ponds
To effectively filter a well
stocked pond, you need a pump that will circulate it's full
capacity every two hours. A pond holding 2400 gallons,
therefore, would need a 1200 gph pump.
But if, for example, you also want a waterfall with a drop of
6ft to the pond surface, the flow rate required would be 1200
gph at 6ft head. In short, you will need a more powerful pump.
Waterfalls
The other thing to bear in
mind with a waterfall is the depth or "thickness" of
the water you would like to have running down it.
Perfect Pump
-
Pump motor designed for continuous operation.
-
Ceramic bearings and shaft without seals give longevity.
-
High hydraulic efficiency means the pumps give
optimal outputs.
-
Capable of large delivery volumes with low
power consumption.
-
Asynchronous motor gives quiet smooth running.
-
Pump can be used with variable speed controllers
for step-less flow regulation (accessory)
-
1
1/2" BSP threaded inlets and outlets for easy dry mounting.
-
Built-in thermal overload protection with auto-restart gives
safety if motor overheats.
-
All internal electrical connections are sealed in resin
for safety.
-
Impellor housing can be dismantled for cleaning if required.
-
High quality functional pump cage with large surface
-
area.
-
Specially designed impellor allows the pumps to
handle solids up to 8mm diameter.
-
Supplied with hose-fittings, 10m cable and impellor housing
key.
