Toro Drip In PC Data Sheet

Micro-Irrigation

Drip

Drip In® PC

Pressure Compensating Dripline

A technologically superior
and cost effective
way to irrigate

• Difficult topographical conditions

• Low and varying water pressures

• Installations requiring longer lateral runss

Features & Benefits:

Highly clog resistant

Due to wide, deep turbulent passageways
and raised inlets.

Extremely accurate flow rate

Due to high quality control standards.

Reduced labor and installation cost

No hole punching, lost emitters or handling
damage. Emitters are factory spaced.

Can’t separate

Because there are no clip-ons or connections.

Lower friction loss

Due to jointless design, allows longer runs and
fewer mainlines.

Versatility

Flow rates available in three hose sizes:
(0.550" (16mm), 0.620" (18mm) and 0.710"
(20mm)

Design Advantages:

High Resistance to Plugging

Water enters the emitter through a raised filtration
system. Debris is deflected upward and away from the
inlet because of the unique construction of the emitter.
This feature significantly reduces the amount of debris
entering the emitter when the system is operating. The
positioning of the raised inlet also prevents sediment from
collecting near the inlet while the system is not operating,
and being ingested into the emitter at start-up. The
emitters filter ensures that only particles smaller than the
emitters cross sectional dimensions will enter.

Three flushing cycles to ensure continued
reliability and performance.

1.Pre-regulating Flush:
The automatic flushing feature is activated at low
pressures during system startup. The diaphragm is
relaxed allowing particles to be freely flushed out.

2.Irrigation Flush:
During the irrigation cycle the diaphragm is depressed
across the compensating chamber. If the emitter begins
to clog, there is a reduction of flow, and pressure
on both sides of the diaphragm begins to equalize.
The diaphragm returns to its relaxed position and
particles are flushed out. The dripper returns to normal
performance.

3.Shut-down Flush:
As pressure is reduced, the diaphragm returns to its
relaxed position allowing accumulated particles to be
flushed out.

Wide Compensating Range

At low pressures, 10 - 15 psi, the emitter behaves like a
turbulent-flow emitter. From 15 - 60 psi, the emitter is
fully pressure compensating.

Flat discharge curve over a wide range of pressures (10-60 PSI)

Chemical Resistance

Drip In PC is manufactured from the highest quality
materials. The emitter body is made from injection
molded polyethylene resins. The diaphragm is made
from silicon. This combination will withstand acids down
to pH2 as well as most commonly used ag chemicals,
fertilizers and chlorine.

Uniformity

Drip In PC’s state of the art manufacturing process and
high quality control standards assures dependable,
uniform and precise emitter discharge. Drip In emitters
have Cv values less than .05, one of the highest rankings
of all manufacturers.
