How the Dana Portable Pump is Fitted and Operated, a Lift of 24 ft. and a Throw of 60 ft. being Claimed.
rplIERE are such a lot of uses for a Power-driven portable pump that it is not surprising that the application of the power of a motor engine to water raising has been carried out in various ways. One of the simplest things in the way of portable power-driven water Pumps is to be found in the Dana portable pump, an illustration of which is 'appended.
This consists of a rotary, centrifugal pump, having only three moving parts, furnished with an intake pipe and an outlet pipe of a length suitable for requirements and mounted on one end of a light frame, the other end of which serves as a bracket by means of which one end of the rear axle of a car can be lifted so as to bring the driving wheel on that side off the ground. The pump is adjustable along the frame and is furnished with a pulley and belt, the latter passing round the free driving wheel, which drives the pump
and gears it up heavily at the same time.
The belt pulley on the pump is 10 ins, in diameter and the pump itself is fitted with 14-in. pipe-threaded connections and, as standard, is furnished
with 25 ft. of suction hose and 15 ft. of discharge hose, with brass connections and a 2k-in. by 1,0-ft. 7-in. rubber driving belt, the net weight of the complete equipment being 1141 lb.
To install it, the pump is bolted to the frame and the other end of the frame placed under the axle and the pump end depressed until it rests on the ground, which has the effect of raising and supporting the wheel, which is then connected up by means of the belt with the pulley. The two lengths of hose are connected up with their threaded connections and the pump is ready for action. For this equipment it is claimed that 5 h.p. to 10 h.p. belt power, delivered at 500 r.p.m.' is the best speed for the pump and the, with the intake pump lowered .into a well or • other water supply, the pump will raise 75 gallons per minute to the pump
• level and will then throw it 50-60 ft. high.
It is claimed that the pump will force water through as much as 2,000 ft. of hose and that the distance from the water level to the pump may be as much as 24 'ft. It can be used on any type of ear and also on a motorcycle, and, as the price of the complete equipment is only about £25, it forms a quickly operable fire' pump.
