Kum ocaklarnda kum karmann deiflik metodlarvardr. Ancak tm dnyada en yaygn olarak kullan-lan yntem artk TOYO kum pompalardr.Dnya zerinde artk en ok kabul gren TOYO kumpompalarnn kullanlmasndaki en byk etken, TOYOpompalarn problemsiz, masrafsz ve son derece ekono-mik bir flekilde yksek miktarda kum pompalayabilme-sidir.

TOYO kum pompalaryla kum karmann dier yn-temlere gre birok avantajlar vardr.

Toyolar ile her blgeden kum karlabilir. Deniz-den, karadan, dadan, nehirden, barajdan hatta derinsulardan bile..

DERIN DENIZLERDE KUMPOMPALAMA fiLEMLER

Deniz veya okyanustan kum pompalama ifllemi 40mden 80 metreye kadar hatta daha fazla derinliklerdegereklefltirilmesini gerektirebilir. Standart yntemlerlegemiye kum ekme veya dip tarama ifllemleriyle yaplanifllemlerde pek ok sorun yaflanr. Ancak TOYO'nun de-rin deniz ifllemleri iin zel olarak retilmifl Derin DenizPompalar derinlikten etkilenmez ve karfltrc sayesindekk apl sistemlerde bile yksek performans ve verimelde edilir.

ManyToyopumps are working in quarries in variousstages of the process:-Extraction of submerged aggregates (sand, gravels,stones, ore)-Mixing and pumping of abrasive slurries (stonescutting water, ore treatment slurries)-Pits washing (rain collecting pits, truck wheelwashing)In the application illustrated on the pictures, the

DP50B is handling a mixture made of very abrasive sand(60%), gravel (30%) and stones (10%). The maximumdiameter of the stones is 6 cm. The pump is extracting100 tons of solids per hour at 15 m depth.

The advantage of the Toyo submersible pump is thatit can handle slurries including stones at higher depththan horizontal pumps can do. Nevertheless, whenever

there are stones in the slurry, it is very important to care-fully verify the percentage of stones and their diameterwhen selecting the pump. Do not hesitate to contact usfor advice in these applications.

Details make the differenceThe market segment of medium duty slurry pumps is

a large volume market.In general the pumps present in that market offer

poor resistance to abrasion and can hardly stir up solidswhich have settled down. They can only pump slurrieswith densities ranging between 1 and 1.1 kg/dm3.

That is the reason why Toyo has launched the GRpumps. This pump is able to handle slurries with 1.15kg/dm3 density and offers the same excellent performanc-es in abrasive slurry pumping as the otherToyopumps.

What makes the GR pumps so different? Robust construction integrating an efficientagitator Wear resistant metallurgies Semi open impeller Double mechanical seal working in oil bath Slow running class F motor with thermalprotection Axial flow of the liquid cooling the motor Service factor of 1.15 Grain size up to 35 mmThese details explain why the GR offer better per-

formances with a lower total cost of ownership than anyother medium duty pumps.
