Product Description

Senninger Model PMR-MF 1” x 1" FPT Regulator - Medium Flow Pressure

Senninger Medium Flow Pressure-Master Regulator is ideal for installations requiring mid-range flows of 2 – 20 GPM, including solid set, drip or other low volume irrigation, as well as center pivot and other mechanical-move systems. Each regulator maintains a constant preset outlet pressure based on its flow / inlet pressure. Note: With no water flow through the regulator, the inlet and outlet pressures will be the same.


  • 100% water tested for accuracy at Senninger’s in-house facilities
  • Can be installed above or below ground
  • Large flow path resists plugging
  • Very low hysteresis and friction loss
  • Pressure Range: 6 to 60 psi
  • Flows: 2 to 20 GPM
  • Backed by a two year warranty on materials, workmanship and performance

  • Caution: Always install pressure regulators downstream from all shut-off valves.
  • Be sure to install pressure regulators in the proper direction. The arrow on the upper housing shows the direction of the flow and should always point downstream toward emitters.
Special note: This pressure reducer is not designed to operate under static (constant) pressure. It must be installed after any valves or timers to operate correctly. Using this item under static pressure will eventually weaken the internal spring and cause the regulator to fail.
