The materials shown below in boldface type are used in the construction of little giant chemical pumps. It is not intended as a guarantee. Before permanent installation test the equipment with the chemicals under the specific. Added consideration must be given to pump selections when the chemical is abrasive viscous in nature or has a specific gravity greater than 1 1.

The following information is intended to be used as a general guideline for pump material selection. Softening loss of strength swelling may occur. Select a material or chemical. Chemical compatibility cannot be read straight off charts and other factors such as temperatures concentration pressure and duration of exposure can.

The ratings for these materials are based upon the chemical resistance only. Click see results note. Kd ceramic material chemical compatibility chart kd ceramic material chemical compatibility chart.
