ò pump out more water due to its unique design.
ò suitable for seawater and passing of solids.
ò can be modified easily for higher heads and capacity.
ò difficult for pilferage.
Applications :
ò aqua culture farming.
ò ideally suitable for petty and para.
ò mass transfer of water from ponds, rivers, sumps, lakes and wimming pools.
(Singlephase/Threephase)
DARLING pumps have also developed little Jumbo pumps with smaller H.P. rating in the range of 0.75,1.0,1 !& & 2 H.P. While the constructional features and design of the little pump is similar to the Jumbo pumps. The little Jumbo pumps are powered with single phase as well as threephase electric supply. The little Jumbo pump is fitted with a sealed, leak-proof single phase or threephase motor. It also has a water jacket through which the water rushes towards the discharge. The motor in little Jumbo pump is also filled with oil for lubrication and also for cooling of bearings & mechanical Seal.
Salient features :
ò high discharge low head pump.
ò in built dry running protection.
ò no need of foundation, suction pump, foot valve & pump house.
ò compact in size, light in weight.
ò life long lubrication arrangement.
ò noiseless, leakproof and instant pumping.
ò easy installation.
ò no attender is required.
ò simple in construction, easy for maintenance.
ò easy installation.
Applications :
ò agriculture farming.
ò most ideal for fountains and waterfalls.
ò industrial pumping.
ò river water pumping.
ò dewatering applications.
ò aqua culture farming.
