  • Simple. Reliable. Profitable. Performance.

    348UM50-8Pumptec are fast becoming the preferred pump system in 12V sprayers as result of our powerful 12V pump technology proven to withstand your workload and be there tomorrow to do it all over, again. Pumptec 12V pump systems deliver performance, simplicity, profit and reliability every day.

    Performance

    • True pressure and volume at the nozzle you can count on for label compliance and accuracy.
    • Consistent pressure for consistent spray patterns providing uniformity of coverage.
    • Pressure up to 150 psi powers through longer hose runs to deliver correct amounts of treatment far from truck.
    • More volume at the nozzle propels treatments to greater heights.

    Simplicity

    • No moving soft parts to wear and fail you on the job.
    • No connecting rods, crankshaft or submerged bearings needed in Pumptec’s design.
    • Single tool – a 3/16” hex wrench – required for easy, mess-free in-field repair.
    • Fewer moving parts to wear or need replacement.
    • Easy upgrade from low performance or unreliable pumps.

    Profit

    • More jobs completed per day with greater productivity of powerful pump system.
    • More time spraying treatments creating more revenue day after day.
    • More hours between service increases up time and equipment availability.
    • Lowest long-term cost achieved through superior design and quality materials.

    Reliability

    Our customers say it best:
    “Pumptec never quits on the job”

  • Line Loss in the Pump System

    One of the challenges encountered by many in charge of proper system design and performance is the physical phenomenon of system performance loss as a result of a volume of water passing through a hose. The resistance a hose creates is similar to the resistance ultimately created by the nozzle, but with a lesser effect.

    Below is a guide chart for reference within the flow range of Pumptec pumps.

    Line Loss Chart

    Understanding this information can prevent under-specifying of pump set and disappointing results.

    A situation many find themselves in is when a small plastic diaphragm pump with long hoses on hose reel is expected to provide critical flow and pressure out the nozzle at the end. A pump rated for 3 gpm and 60 psi, used with ⅜” hose cannot offer much performance at the end. According to the chart, the line loss is 50 psi per 100 ft of hose.

    The benefit of a Pumptec plunger pump is extended pressure capabilities to overcome the resistance in the hose. For example, a standard Pumptec pump set, 114T-075/M15 (Spray Basic), has a pressure rating of 150 psi to provide desired nozzle performance at the end of long hose runs.

    The chart can also be used to maximize system performance. If, for example, the system produces 3 gpm and has 150 capability, and 100 psi is needed at the nozzle the chart can assist. If the hose is 100 ft long, then ⅜” hose is a good choice, but if the hose length is longer then ½” hose would be better.
