 DO NOT run orifices with squeeze pumps. This cannot be done because squeeze pumps do not put out enough pressure for an orifice system. Squeeze pumps only put out 2-3 pounds of pressure.

NEW High Pressure Injector Orifice

Schaffert Mfg.'s new high pressure injector orifice is made to screw into the high pressure kit for our 2x2 fertilizer disc (G2) and 2x2 fertilizer tube (for Case IH).

These 2x2 systems work well with Schaffert's pump systems.

Features of the orifice include:

  • Screws inside 3/8" stainless tube
  • Easy to install with an Allen wrench
  • Orifice OD is 5/16"
  • Stainless steel compact design
  • 10 color coated orifice sizes
  • Injects high pressure, 2-80 GPA
  • Universal models - fits many machines
  • Allows tube to be closer to soil surface, eliminating trash buildup

To find the correct injector orifice for your high pressure kit, you will need to know:

  • Number of rows
  • Row spacing
  • Travel speed
  • Pressure
  • Kind of fertilizer
  • Product weight
  • Gallons per acre

PLEASE NOTE: We normally recommend using only 1 orifice under pressure when running 7-15 lbs of pressure. However, using 2 orifices under pressure can be beneficial because it will help eliminate fertilizer splatter or misting/volatilization of fertilizer when done in the following manner:

  • Use the correct size orifice above for 15-30 psi pressures
  • Use 2-3 times size orifice below, creating 5-7 lbs pressure to stream fertilizer into the soil
NEVER USE 2 OF THE SAME SIZE ORIFICES IN YOUR SYSTEM!!!

 DO NOT run orifices with squeeze pumps. This cannot be done because squeeze pumps do not put out enough pressure for an orifice system. Squeeze pumps only put out 2-3 pounds of pressure.
