. Features & Benefits Quiet, dependable power and proven performance. 1600 Series In-Line pumps meet the latest Rear pull out design allows servicing of the pump without disturbing the piping. industry standards for hydraulic performance and reliability. Each is backed by Taco Replaceable "cooler running" bearing cartridge extends bearing life and permanently sealed grease lubricated ball bearings makes it virtually maintenance free. Inc.

. Standard ceramic seal meets the demands of a wide range of application requirements, and the new "unitized" design facilitates quick and easy replacement simplifying maintenance. Replaceable corrosion resistant shaft sleeve incorporates a "built in" slinger to deflect water away from the bearing cartridge in the event of a seal leak. 1/4 NPT pressure tappings on suction and discharge connections. Companion flanges included.

. Commercial Hydronic Application Information Useful Definitions Flow is a volume measure to establish pump capacity per unit of time, usually as GPM. Shut-Off Head is the head developed by a pump at zero flow. Head is a pressure measurement represented by how high the pump can lift a column of liquid, usually in feet. To convert the popular pressure expression P.S.I. to feet of water, multiply P.S.I. X 2.31.

. Part I – Fundamentals A centrifugal pump operated at constant speed delivers any capacity from zero to maximum depending on the head, design and suction conditions. Pump performance is most commonly shown by means of plotted curves which are graphical representations of a pump’s performance characteristics. Pump curves present the average results obtained from testing several pumps of the same design under standardized test conditions.
PAGE 6
. Commercial Hydronic Application Information Pipes, valves and fittings create resistance to flow or friction head. Developing the data to plot a system curve for a closed Hydronic system under pressure requires calculation of the total of these friction head losses. Friction tables are readily available that provide friction loss data for pipe, valves and fittings. These tables usually express the losses in terms of the equivalent length of straight pipe of the same size as the valve or fitting.

. So-called unstable curves are those with maximum head not at zero, but at 5 to 25 percent of maximum flow, as shown by the curve for Pump 1 in Fig. 3 – 1. Single Pump In Open System With Static Head The term unstable, though commonly used, is rather unfortunate terminology in that it suggests unstable pump performance. Neither term refers to operating characteristic, however. Each is strictly a designation for a particular shape of curve.
PAGE 8
. Commercial Hydronic Application Information From a practical point of view, the shutoff head should be 5 to 10 percent higher than the static head because the slightest reduction in pump head (such as that caused by possible impeller erosion or lower than anticipated motor speed or voltage) would again cause shutoff head to be lower than static head.

. The Taco pump performance curve below (Fig. 4–1) includes a plot of the required NPSH for a Taco Model 1506. If a pump capacity of 105 GPM is used as an example capacity requirement, reading vertically from that GPM rate shows a required NPSH of 4 feet. An available system NPSH greater than 4 feet would, therefore, be necessary to ensure satisfactory pump performance and operation. Curve no. 2015 Min. Imp.
