Electrical news and engineering . ject of producing the best resultsin pumps ranging from i^ to 6 inch in size, with a capacityof from 300 up to 60,000 gallons per hour. It is neitherof the piston, centrifugal or semi-rotary type, but is con-structed upon a new principle which practically combinesall these systems and delivers a constant stream withoutthe usual air chamber on the discharge. This pump is suit-able for waterworks in small towns and is also very suit-able for dealing with gas exhausters, oil, wine, vinegar, acids,spirits and general liquors in breweries and distilleries,creameries, hand and steam or gasoline fire engines, hotliquids, boiler soap, tar, fats and other liquids of high grav-ity. The impellers and casing can be supplied in metals tosuit the liquor to be handled. This pump would prove val-able to agriculturalists, florists, market gardeners as a spraypump or for water supplies. The suction of the new type of Albany pump is greatelyincreased, and it is now capable of lifting 28 feet and is good. for heads of aOO feet. An important feature in design is thearrangement for overcoming slip and leakage between therotating impellers and the casing of the pump. A continu-ous water-packing forms a sealed watertight joint or cushionbetween the impellers and the casing. Recent tests of sev-eral of these pumps made at the School of Practical Science,Toronto, show that the efficiency ranges from 40 per cent,in the smaller to 80 per cent, in the larger sizes. The Albany pump, we understand, is now being instal-led in all the new battleships and cruisers both by the Eng-lish and French Admiralties. Canadas new cruiser Niobe has these pumps installed in her engine room. A largenumber of these pumps are already in use in all parts of theI^ominion, and the manufacturers, for whom Mr. A. , of Toronto, is the Canadian distributor, advises usthat they are giving the best of satisfaction.
