Significance and Use
4.1 Pumpability of heat transfer fluids depends upon the configuration of the system in use, pumps and their installation, and the physical properties of the fluids being transported. The fluid’s ability to pump efficiently is key to the economy of the system operation and heat transfer fluid life. The test methods listed in Section may be considered as guides for determining the pumpability of heat transfer fluids under specific operating conditions. Information gained from use of this guide will aid in the selection of pumping equipment and its installation.
1.1 This guide covers general information, without specific limits, for selecting and evaluating pumpability characteristics of heat transfer fluids at both low and high temperature. This guide is a compendium of information and does not recommend a specific course of action. This guide provides additional information on pumpability topics found in companion guides for evaluating heat transfer fluids, Guides and .
1.2 Pumpability of heat transfer fluids is dependent on both fluid properties and the design of the fluid handling system that stores and transports the fluid, and therefore presents a number of pumping options. This guide is considered particularly useful for identifying pumpability options. The listing of test standards and guides is not all-inclusive and additional standards and guides may be useful.
1.3 The values stated in SI units are to be regarded as standard.
1.3.1 Exception—Other units are provided for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Users of heat transfer fluids should be especially mindful of potential fire and explosion hazards.
