TUBE REPLACEMENT – SAFETY INFORMATION
RISK OF CHEMICAL EXPOSURE
To reduce risk of exposure, check the pump tube regularly for leakage. At the first sign of leakage, replace the
pump tube.
To reduce risk of exposure, the use of proper personal protective equipment is mandatory when working on or near
chemical metering pumps.
To reduce risk of exposure, and also prior to service, shipping, or storage, pump generous amounts of water or a
compatible buffer solution to remove chemical from pump.
Consult chemical manufacturer and SDS sheet for additional information and precautions for the chemical in use.
Personnel should be skilled and trained in the proper safety and handling of the chemicals in use.
Inspect tube frequently for leakage, deterioration, or wear. Schedule a regular pump tube maintenance change to
prevent chemical damage to pump and/or spillage.
PINCH POINT HAZARD
Use extreme caution when replacing pump tube. Be careful of your fingers and do not place fingers near rollers.
HAZARDOUS PRESSURE/CHEMICAL EXPOSURE
Use caution and bleed off all resident system pressure prior to attempting service or installation.
Use caution when disconnecting discharge line from pump. Discharge may be under pressure. Discharge line may
contain chemical.
NOTICE: Indicates special instructions or general mandatory action.
DO NOT
apply grease, oil, or lubricants to the pump tube or housing.
Prior to pump tube replacement, inspect the entire pump head for cracks or damaged components. Ensure rollers
turn freely.
Rinse off chemical residual and clean all chemical and debris from pump head components prior to tube
replacement. Apply AquaShield
™
to main shaft and tube housing cover bushing during tube replacement.
DO NOT
pull excessively on pump tube. Avoid kinks or damage during tube installation.
Inspect the suction and discharge lines, injection point (into pipe), and injection check valve duckbill for blockages
after any tube rupture. Clear or replace as required.
