AV-284 Pump Wash

Pump Flushing Agent

AV-284 Pump Wash™ is a non-flammable, non-drying compound that removes uncured polyurethane resin from grouting equipment. AV-284 Pump Wash is designed to be stored in the pump for extended periods between pump usages.

Once grouting operations are completed and all residual grout is removed from the pumping system, AV-284 can be introduced to maintain pump. As a side note, the material may be stored in grouting equipment for extended periods when pump is not in use.
