Chemical compatibility must have prime consideration for pump selection. However, consideration must be given to pump selections when the liquid is abrasive, viscous, high temperature or has a specific gravity greater than 1.1. Please remember that in any given application, many factors such as concentration, agitation, pressure, time and temperature influence chemical resistance.

The data presented herein is based on information furnished by manufacturers. It should be used as a guide only and may be considered as a basis for recommendation, but not as a guarantee of performance. We assume no liability for the data accuracy or inaccuracy, completeness or incompleteness.

Final determination of the suitability of any information or material for the use intended, or the manner of use, is the sole responsibility of the user. Whenever possible STANDARD recommends that the user test the desired product under actual working conditions to determine suitability.

Materials for STANDARD Magnetic Coupled Pumps
