Biogas Production Plant equipped with BIOGAS Pumps NOVA ROTORS DHS+DN of 480 kw. ( moisture sludge, and animal slurry and similar), in which Diamond Series Pumps type DHS and DN are used together to pump digested output mixed with silage inside the digester.
The particular combined use technique of the two pumps and the homogeneity of the pumped product, allows NOVA ROTORS to reduce the discharge pressure and therefore consumption.
The degree of homogenisation is also higher if compared to a mixing process in the collection tank.
NOVA ROTORS Diaphragm Pumps etc
Diaphragm pumps supplied with compressed air available in various material designs (metal and plastic); It is possible to transport aggressive, abrasive and high density media. The operation starts with the supply of compressed air through the distribution system directing the air to one of the membranes.
Diaphragms are connected by a common axis. One diaphragm that feeds the feed is pulling the other one which sucks in the medium. Again, the cycle repeats with the reversal of direction of action.
Sanitary pumps (food pumps) and ATEX certified pumps by Nova Rotors are available. Screw pumps belong to a family of rotary displacement pumps, where liquid flow through the pump is caused by displacement of the liquid from the pump by the rotating rotor relative to the stationary station.
Thanks to the soft, almost pulsed flow of liquid through the pump, very good self-priming properties and unmanned construction, the screw pumps provide the ability to transfer liquids with very high viscosity and density without damaging the product structure.
Screw pumps can be found in all industries for the most demanding applications.
The gear pumps provide very favourable conditions for the flow of liquid, as its flow direction is slightly deviated by the flow of the pump. This has resulted in Nova Rotors having outstanding pump-ability for self-priming and gentle pumping, without disturbing the flow of liquid, and also pumping liquids with very high viscosity.
Today, Nova Rotors pumps are considered as the most technologically advanced with unique operating properties. Pumping in every direction, ease of operation during operation of the pump, robust and uncomplicated construction.
Vortex pumps belong to the group of rotary machines. The principle of operation is to increase the liquid mole in the rotor supplied with blades and rotating at constant speed. Fluid continuously flowing through the impeller is subjected to centrifugal force or the action of the buoyant force of the blades, or both.
The energy of the motor is transferred to the liquid by means of the rotor, causing it to increase the pressure energy and kinetic energy. When the liquid is removed from the rotor, the kinetic energy in the pressure energy is further transformed.
The increase of kinetic energy and pressure depends on the rotor structure and its rotational speed. The cam pumps are rotary displacement pumps.
Rotating oppositely the rotors (called rotors, cams or knobs) in the suction section of the pump, moving away from each other creates an enlarged empty space that fills the pumped liquid. Then the liquid is transported by cams along the wall of the pump housing.
Climbing cams reduce the free space displacing the medium outside. The uniqueness of the principle of operation is based on the fact that the cams are driven separately by their own shafts – this leads to the lack of friction of the cams by itself or to any other part of the pump.
Nova Rotors Conclusion
This guarantees a gentle pumping process and very long pump life.
Magnetic pumps – Transferring the motor from the motor to the pump section is done by means of a magnetic clamp.
Magnetically polarized, one of which is connected to the drive shaft and the other is mounted on the impeller of the pump.
Magnets are separated by the internal pump body – there is no mechanical connection between the pump and the motor.
No axle sealing is necessary, which often causes leaks in conventional pumps. No seals are broken into safety and low LCC costs. 80% of the pump failure is due to sealing damage. They maintain continuous work with minimum maintenance, they have hermetic constructions. Magnetic pumps block dangerous liquids, crystallising in contact with air.
