Principle

A MAXIMUM PERFORMANCE PNEUMATIC SYSTEM !

THE PULSED AIR-FLOW SYSTEM
(used on several models of pneumatic seeders for plant cover)
1 — The seeds fall into the air-flow.
2— The seeds are pushed by the air-flow, but some types of seed are blown back by the turbulence.
So, not all types of seeds can be sown !
To avoid this, ...

THE ECV BY SEPEBA USES THE VENTURI NOZZLE PRINCIPLE

Thanks to its original pneu-matic system that reduces blowback phenomena and optimizes seed transport, the SEPEBA distributor is as efficient with light seeds (ray-grass) as with heavy ones (wheat).

ACCURATE DOSING FOR VERSATILE SEEDING

At SEPEBA, the accuracy of the dosing is one of our main concerns. Indeed, a plant-cover seed-drill must be able to seed precisely very small dosages (like 1.5 or 2 Kg/Ha of colza) as well as big quantities (like 80 Kg/Ha of cereals, or even more. To get these results, we have worked on differ-ent points. One of them is the use of a height-adjustable brush seal which regulates the filling of the rotor to give per-fect regularity.

ACCURATE DOSAGE FOR SEMIS VERSATILE

Another point of the ECV 2 is its easily interchangeable ro-tors, which allow the SEPEBA seeder to accurately spread small or big quantities of grains of different sizes and shapes. The SEPEBA plus-point : We can manufacture tai-lor-made rotors for you, to meet your specific needs. Of course the maximum quantity of grains per Ha vary de-pending on the width of the seed beds and the sowing set-up being used (slope of seed-tubes in particular).

Example flow-rate table for sowing on 4-5 m wide at 8-10 Km/h. These points are given for information purposes ; they vary depending on the size of the seed, its shape, sowing conditions (slopes in particular).
Certain high flow-rates for large seeds require the use of fans or air-turbines of higher volume than the standard fan.
Capable of sowing a very wide range of seeds, the SE-PEBA plant cover distributor has been designed to provide either very high or very low doses thanks to the design of its blower, its various rotors and its adjustment system.

VERY ACCURATE LOCALIZATION OF THE SEEDS

The SEPEBA seed-spreading devices are designed to place the seeds very accurately, on a band of about 30 cm in rela-tion to tractor’s direction of movement. This allows the seeds to be placed exactly where you want : between the discs and the rear-roller or even between 2 rows of discs …
Definitely an essential factor in the success of your sowing !

EASILY ADJUSTABLE, FAST AND RELIABLE FLOW-RATE

We’ve chosen a flow-rate adjustment control using an elec-tronical speed control with a flow-rate proportional to ground speed. We use for this a Gemini system, which offers a good range of helps for the farmer : help to flow-rate adjustment, counter of seeded surface, indication of real flow-rate.. ;

We can supply as well a non FPS electronical adjustable speed control . It enables to get a less expensive solution, with a wide range of flow-rates and the adjustment of the do-sage from the driving post of the tractor.
