![]() (2.) That in bucket dredges, the actual engine power is roughly seven times that theoretically sufficient to do the work. These results cannot be called conclusive, but they serve to show: (1.) That the frictional losses of power in gold-dredging are very great, probably 600 to 700 per cent, of the power theoretically sufficient to do the lifting work. The difference in the weight of the gravel lifted, while under the water level, has been disregarded and, in estimating the steam power in compound engines, it is assumed that the low-pressure develops the same power as the high-pressure cylinder. The calculations are made in theoretical horsepower, and for easy references are given in tabular form. With lower overall weight and kW along with Tsurumi’s 3 year manufacturer’s warranty these offer an excellent solution if you find the DP series is too large for your application.In calculating the horse-power consumed by suction and by bucket dredges, figures have been taken from the various official reports on the mining industry in New Zealand, dates and pages in each instance being given. ![]() All heavy duty motors have internal overloads fitted allowing for direct connection to a power supply and are supplied with at least 20m of heavy duty rubber power cable.ĭepending on the pump selected this range is suitable for pumping sand, bentonite and pulverised solids in suspension with a free passage size ranging from 10mm - 30mm ![]() Tsurumi have expanded on their agitator series of pumps which now includes the KTD, NKZ3 and GPN range to complement the existing KTV2 and KRS2 pumps.Īll pumps have an impeller and agitator constructed from hard chromium iron along with a hard faced (silicon carbide-silicon carbide) double mechanical seal running in an oil chamber for positive seal lubrication in any position. ![]()
