PumpRight Pressure
Recommendations (with 10 lb check
valves):
• Minimum 20 PSI
• Maximum 80 PSI
Tower Electric Pump Pressure
Recommendations (with 4 lb check
valves):
• Minimum 10 PSI
• Maximum 30 PSI
Chart is for 28-0-0 Fertilizer @ 70°
• Heavier fertilizers (like 10-34-0) will
have 5-15% less flow than chart
indicates for a certain pressure
• Cold fertilizers will cause system
pressure to increase at a given
application rate.
• Tower Electric Pump Systems will
have reduced flow and increased
electrical current draw due to cold
fertilizer increasing operating
pressure. Use the largest orifice
possible for cold weather
operation.

Colored Disc Orifice assembles under the
check valve cap in most cases. (Drop the
orifice with the hole down into the cap,
then put the gasket on top of it.) The ori-
fice can also be installed in a manifold
(common on grain drills).
