- Book Description
- This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1900 Excerpt: ...until now they are in point of capacity, efficiency and workmanship the best on the market. This class of Pumps is intended for elevating large quantities of water under comparatively low heads, and they will show a greater economy than any other type of Pump. They are extremely simple. The only moving parts being the runner and shaft, there is practically nothing to wear out, and they will last, therefore, for years without any expenditure whatever in repairs. Many builders of Centrifugal Pumps state a capacity for each Pump which can only be obtained with an enormous expenditure of power and very high speed. In the following tables we only give the economical capacity of our Pumps: that is, the capacity at which they will take the least amount of power. By running them at a higher speed a greater capacity can be obtained, but, at the same time, the efficiency is reduced so that the power required to operate them will be greater than if a larger size Pump were used. The table of revolutions per minute given below is accurate, and if the Pumps are run according to the speeds there given, the discharge will be that given in the tables. Centrifugal Pumps are used very extensively for irrigation and drainage, sewage pumping, dry docks, paper and pulp mills, tanneries, dyers, distillers, starch factories, excavations, etc., and they are especially to be recommended as no solid matter in suspension will prevent their operation, because, as they have no valves whatever, there is nothing to clog up or become foul. Refers to low-lift Pumps. Above table gives correct speed of our Pumps as employed under usual conditions of pumping. lf water must be forced through a number of bends and elbows, or a great length of piping the above speed must be somewhat increased. Us...
