    Excellent Pump
    This shopper rated the product 5 out of 5 stars

    Used this pump for three years on a 300 gallon agricultural sprayer with excellent results- spraying 8-12 rows with up to 16 nozzles, including liquid nitrogen and roundup with no issues at all. Always flushed system with water, removed pump, and lubed up the rollers with a little transmission fluid for storage. Clean trans fluid out by running a little water/detergent through after storage and go again. Seals and bearings have held up so far, even after being exposed to roundup/nitrogen. Can't beat the performance for the price.
