DOA SP65 TRASH WATER PUMP SPIDER EXCAVATOR

SP55 and SP65 are powerful dewatering pumps for muddy waters , trash waters and excavation waters designed for use and as accessories of excavators and back hoe loaders, the pumps are installed on the bucket place like a typical mounted breaker or just like any boom attachment, exploit the large hydraulic power of the machines transforming them into high efficiency pumping units. The use and installation are easy and quick, the mounted breaker circuit ( that is available on all machines boom) always fits the hydraulic characteristics of the pumps that do not need regulations of pre existing circuit setting of flow and pressure. Pumps are ideal in all fast pumping works and movements of large volumes of waters , are really formidable for function, operation and power in emergency operations after floods and natural catastrophes THE ADVANTAGES ARE MANY AND CONCRETE -High performances, the ratio weight/dimension/power is unmatchable by other type of pumps , water movements up to 8000L/min - water heads up to 40 mt -Simple and practical use, can be installed in few minutes transforming machines into high efficiency dewatering units with performances superior to large Diesel self priming pumps ( that are much more bulky and heavy and have transport problems and general costs much higher) -Permit total use of the machines increasing the versatility and maximising the economy -Can pump very muddy waters and very loaded trash fluids like those in aseptic tanks -Possibility to install the accessory SG4 ( that can be bought separately ) that allows to reduce to a more fluid state thick liquids or liquids with dry surface or with semi solid conglomerates that would prevent the pumping if not minced and mixed with water ( like mud balls, sludges etc) -Digest everything ! The special impeller with knives can shred sea weeds, grass, rags, ropes, trash sacks, branches and linear fibres suspended in the fluid and with dimension up to 50 mm -The earth moving machines can transit in deep water and on rough terrains and thanks to the boom length the pumps can be positioned and pump in difficult position points and in dangerous situations , on muddy terrains or that would be impossible to transit or be reached by typical wheeled type of pumps -Very robust ! Can run dry without problems, require minimal easy maintenance that can be made by non expert personnel -No electric current means implicit safety ! Pumps can be used even having people near in the water ( situation very dangerous and prohibited by law with electric pumps ) -Can pump petrol and oil based fluids and many dangerous aggressive fluids -Can be disassembled from the outside brackets and used as normal submersible pumps ( see imagine B) -Can be installed on floaters to suck only from the surface like " skimmers" or just to avoid sinking on the bottom -Equipped with high quality piston hydraulic motor that assures high efficiency and thanks to the possibility to work up to 350 Bar does not need pressure and flow regulations More info: http://www.doa.it/hydraulic_water_pumps.php?lang=eng
