Liquid Compatibility Guide

Introduction
This Liquid Compatibility Guide was compiled from currently available data supplied by the manufactures of wetted materials used in chemical pump construction. Many variables influence the degree of liquid attack for example if theliquid is still or agitated, alternate wet and dry conditions, amount of aeration, cold, hot or boiling temperatures, concentration and saturation, moisture content, pure or mixed liquids creating fuming conditions, time of exposure...and others. Because of the foregoing, this listing can only be offered as a guide. ITT Jabsco cannot certify nor warrant the data. All data and subsequent pumpsuitability for a specific application should be confirmed by customer’s field trial including satisfactory pump life endurance test before ordering pumps. It is the policy of ITT Jabsco for continual improvements, we would therefore welcome any additional liquid compatibility information or comments on the foregoing.

Key Symbols
This Liquid Compatibility Guide was compiled from various charts andtables provided by material manufacturers. Their nomenclature was condensed into key symbols. Their descriptive words shown below can aid in making judgments as to pump suitability for specific applications. A Excellent, Fully Resistant, Suitable, Recommended, Excellent Compatibility. Good Resistance, Fair Resistance, Moderate Resistance. Fair to Poor, Minor Effect, Slight Attack. Not Recommended,Severe Effect, Unsatisfactory, Do Not Use. (Blank Space) Information Lacking at the Time of Printing.

Liquids Listed
Generally compatible/incompatible as indicated in the tables. Check with customer for other factors (Hygienic, presence of solids etc.) before confirming pump suitability.

Material Selection Notes
Dependent on pump type and availability 1. If Abrasive Liquid-Pump speed shouldbe low and seal should have hard faces, if applicable. 2. If Crystallizing Liquid-Use flushed mechanical seal or seal with hard faces, if applicable. 3. If Hazardous Liquid-Use double mechanical seal or make other arrangements, if applicable. 4. All pump seals are liable to leak due to wear or age. It is the responsibility of the user to take safety precautions to prevent personal injury orenvironmental contamination, due to leakage of toxic, flammable, corrosive or otherwise, hazardous liquids.

Liquids Not Listed
This guide will be revised and updated as new listings are made available. Liquids not listed can be referred to the factory for investigation on an individual basis. Ask the customer if the option offered is acceptable. Alternatively, does he already have information onpump material required?

General Notes
1. Pumping of Gasoline by ITT Jabsco pumps is not recommended. 2. Flushing of pump after use with appropriate liquid prolongs its life.
