mRoy AP/B Series Fertigation System

• What flow rates can the A Series handle, and how precise is the adjustment?
  • The A30 operates up to 30 gallons per hour with a true 10:1 turndown ratio.
  • Flow is adjusted using a micrometer-style percent knob with ½% increments for precise, repeatable settings.
  • The knob adjusts pump stroke length and maintains a predictable output relationship.
  • Steady state accuracy is ±2% of full capacity across the turndown range.
• What products can I inject with the A Series?
  • Designed for liquid fertilizers, crop protection products, wetting agents, and compatible liquid soil amendments.
  • Slurries or non-soluble products require a slurry-ready configuration with upgraded internal components.
• How does the A Series ensure even distribution?
  • Operates at 185 strokes per minute, producing evenly spaced injection pulses.
  • Uses the Mister Mist’r® injection quill for immediate dispersion.
  • Additional mixing occurs through system piping and irrigation components.
  • Over 43 years of field use with no documented distribution issues when properly installed.
• Can I adjust the injection rate while the pump is running?
  • Yes. The micrometer-style knob allows smooth, real-time adjustments.
  • No need to stop the pump or use tools.
  • Provides more precise control than many competing systems.
• What suction hose size should I use?
  • Always use the recommended size or larger—never smaller.
  • Proper sizing ensures correct NPSH, consistent flow, and long pump life.
  • Undersized hoses can cause cavitation, poor priming, and damage.
• Is the A Series available in 12 VDC?
  • Yes, along with multiple AC voltage options.
  • 12 VDC systems are typically powered by engine-driven alternators.
  • Output may vary slightly due to voltage fluctuations.
• Why doesn’t the system include a plug or suction hose?
  • Electrical and plumbing needs vary by installation.
  • Allows installers to select the correct components for their setup.
  • Avoids one-size-fits-all limitations.
• What maintenance is required?
  • Annual maintenance and proper winterization are strongly recommended.
  • Helps prevent freezing damage, corrosion, and premature wear.
  • Reduces likelihood of major repairs.
• Can I order special configurations online?
  • No. Acid-ready and slurry-ready systems must be ordered directly.
  • These require specific materials and configuration for safe operation.
• Is the A Series limited to center-pivot systems?
  • No. Also suitable for:
    • Linear move systems
    • Drip irrigation
    • Solid-set systems
    • Greenhouses
    • Other pressurized irrigation setups
• Where can I find installation and operating requirements?
  • All details are in the MacRoy A Fertigation System Operating Manual.
  • Must be reviewed before installation or operation.
• What warranty comes with the A30?
  • Coverage varies by component and is defined in the manual.
  • Pump drive components have multi-year coverage under normal use.
  • Motors are typically covered for one year by the manufacturer.
  • Improper use or installation may void warranty.
• Do I need to read the operating manual?
  • Yes. It includes critical information on:
    • Pressure limits
    • Suction requirements
    • Electrical setup
    • Calibration and safety
  • Many issues stem from skipping steps outlined in the manual.
• What is included in the startup kit?
  • Ships in a branded drawstring bag.
  • May include:
    • Safety glasses and gloves
    • Reference materials
    • Basic tools and supplies
    • Custom oil funnel
    • ApplyYourself® app information
  • Designed to support safe setup and long-term operation.
