Marksman Models
Marksman Hydra-Cell Pump
Flow Range: 10-180 GPH
Max Operating Pressure: 125 PSI
Power Options: 480VAC 3-Phase, 110VAC
Durable and robust industrial grade pump with years
of proven use in fertigation and chemigation
applications. Variable Frequency Drive (VFD) varies
motor speed to achieve desired application rate.
Marksman 12VDC Pump
​
Flow Range: 6-60 GPH
Max Operating Pressure: 50 PSI
Power Options: 480VAC 3-Phase, 110VAC, 12VDC
The economy solution for low pressure irrigation
systems. This system utilizes a 12VDC motor to drive
a diaphragm type pump. Works well in low pressure
irrigaton systems requiring low to medium application
rates.
Marksman No-Pump - Existing Injection Pump Control
​
Flow Range: Determined by Existing Pump
Max Operating Pressure: Lesser of 125 PSI or Maximum of Pump
Power Options: 480VAC
Durable and robust industrial grade pump with years
of proven use in fertigation and chemigation
applications. Variable Frequency Drive (VFD) varies
motor speed to achieve desired application rate.
Marksman 550 Tank Skid with Hydra-Cell Pump
​
Flow Range: 10-180 GPH
Max Operating Pressure: 150 PSI
Power Options: 480VAC 3-Phase, 110VAC
550 gallon cone-bottom tank with variable speed propeller
agitation. Factory assembled with Marksman Hydra-Cell
system. Attach it to your trailer and it’s ready to go to the
field.
Features and Benefits
Flow Measurement
​
All Marksman models utilize an electromagnetic flow meter to measure
flow rate of fertilizer or water/chemical mixture. Electromagnetic meters
have no moving parts to lodge, stick or wear. They precisely measure
any electrically conductive liquid.
Flow Control
​
Set the desired flow rate (GPH) for your application and Marksman will control the pump output to achieve
the desired rate for the entire application. Changes in product viscosity due to temperature variation,
changes in head height of tank, and other variables that change flow rate through traditional metering
pumps, are a thing of the past. Marksman ensures you get the exact application you need.
Water Proportional Control
​
Marksman changes the chemical or fertilizer flow rate in response to changes in water flow such as corner
swing-arm systems. Marksman ensures the correct rate is applied regardless of the swing arm position.
Auto Run on Power Up
​
At power up, Marksman will automatically start pumping. Automatically resume injection after power shut down due to load control. Useful in drip irrigation to apply set batch size to each zone of system.
Batch Mode
​
Inject set number of gallons, then turn off.
Shut Down Alarms
Off Rate Alarm -
If tank runs dry or the strainer plugs up and Marksman cannot achieve the desired flow rate, Marksman will automatically shut down. Utilize Marksman pivot shut down relay kit to stop the pivot as well.
Low and High Pressure Alarm -
If injection pressure drops below the minimum pressure set point,
Marksman will shut down. Eliminates hours of costly and harmful spills due to a broken hose.
Water Pressure Low and High Pressure Alarm -
With optional water pressure sensor, Marksman will shutdown based on too low or too high of water pressure.
Record Keeping - Data Logging
Marksman keeps a complete record of every application. Every 10 minutes it logs an entry which includes field number, date, time, flow rate set point, actual flowrate, pressure and batch total. You will know when, where and how much was applied.
Regulatory and Supply Chain Reporting
This provides the necessary information you need for regulatory reporting. It also provides a record that can be used throughout a supply chain that wants to know more details of exactly how your product was grown, especially on fruits, vegetables and specialty crops. The log file is an Excel file that is downloaded directly from the Marksman via USB drive or directly from the cloud when equipped with remote connectivity.
