    xtreme lower LOW MAINTENANCE DISPLACEMENT PUMP
    Downtime from fluid contamination entering the displacement pump costs you time and money. In the past, the pump had to be removed from the sprayer and brought to a mechanic shop where it was further disassembled, cleaned, repaired, sent back to the job site, re-installed onto the sprayer and then put back into service.
    With the new XTREME DISPLACEMENT PUMP featured on the model 4520, downtime is reduced to a minimum. The innovative pump design allows the operator to disassemble, service, reassemble, and return to production without having to remove the pump from the sprayer. All this in minutes instead of hours and with only a few common hand tools.
