Low consumption pumps

Circulation pumps

Water in a natural pond must circulate. Always. This is a fundamental principle. For volumes in a domestic natural pond, it is usually adequate one circulation pump or at most two in parallel. Even here the choice is to opt for pumps with low energy consumption and durable quality.
The factors affecting the choice are:
  • Volume of water to be filtered
  • Number of needed cycles
  • Distance and height difference between position and pump water intake
  • Any pressure loss along the way (additional filters, route deviations, etc.)
  • The pump is an element that requires maintenance (at least one annual cleaning of the impeller)
  • The pump must be protected with a possible pre-filter in order to safeguard the impeller from dirt and objects.
 

Varioflow DC pumps with electronic control

Innovative pumps, equipped with highly efficient technology. Permanent magnet motor with 6-pole direct current with electronic speed regulation.
The VarioFlow pumps have a continuously adjustable flow from 0 to 100%, in 1% increments. The reduction in flow allows a proportional reduction in consumption.
Normally, when a traditional pump is installed, a flow control valve is used without any benefit in terms of consumption; with these DC pumps, on the other hand, through digital control, a great saving on energy consumption is also achieved.
Pumps with next-generation technology:
• High efficiency neodymium permanent magnet motor
• 6-pole motor with high torque and excellent control characteristics
• External control panel with frequency regulator for variable speed control
• Can be used in dry or in water
• Fully adjustable
• Open impeller for conveying dirt particles up to 8 mm
• Integrated memory for automatic saving of settings in the event of a power failure
• Engine, monitor and microprocessor of European design

The VarioFlow pumps have a continuously adjustable flow from 0 to 100%, in 1% increments.
The reduction in flow allows a proportional reduction in consumption.
The graphs show the characteristic curves of the pumps with four different percentage values. Power consumption is indicated at the beginning and at the end of each curve. You can see the reduction in energy consumption at low speeds.
Normally, when a traditional pump is installed, a flow control valve is used without any benefit in terms of consumption; with these DC pumps, on the other hand, through digital control, a great saving on energy consumption is also achieved.

How UV-C works

UV-C is electromagnetic radiation, which penetrates the cell wall of a micro-organism and damages the nucleus.
This destroys its ability to multiply.
The organisms are finally destroyed and have to be filtered from the water.

 
Before and after radiation

UV-C radiation damages a micro-organism's DNA molecules so that it can no longer multiply.
 

 
 

Not all micro-organisms are eliminated

The UV-C radiation can only eliminate organisms that are transported through the UV-C lamp in the water flow.
Useful organisms, such as nitrifying bacteria, do not float in the water, but attach themselves to carriers, such as the lining, plants, and filter filling, etc.
String algae also attach themselves to carriers and do not end up in the device.
 

The relationship between the flow capacity and the strength of the radiation

Scientific research has shown which UV-C radiation level eliminates the different types of micro-organisms.
The faster the water flows through the device, the shorter the radiation time to which a micro-organism is subjected.
Suspended algae, which cause the water to turn green, are eradicated with a short burst of radiation.
In order to destroy more effective organisms, such as parasites that could cause disease among koi, the burst of radiation must be longer, in other words, the water must flow through the device more slowly.
For swimming pools, the disinfection of the water is established as a standard, which is also used for swimming ponds, here the water's flow capacity is even slower.
