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.
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.
Pump motor designed for continuous operation.
Ceramic bearings and shaft without seals give longevity.
High hydraulic efficiency means the pumps give
Capable of large delivery volumes with low
Asynchronous motor gives quiet smooth running.
Pump can be used with variable speed controllers
for step-less flow regulation (accessory)
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
Impellor housing can be dismantled for cleaning if required.
High quality functional pump cage with large surface
Specially designed impellor allows the pumps to
handle solids up to 8mm diameter.
Supplied with hose-fittings, 10m cable and impellor housing
