SELF-CLEANING, PRESSURE COMPENSATING DRIPPERLINE

Description

DURA-FLO^TM PC Dripperline is a low volume dripperline with internally bonded and evenly spaced pressure compensating emitters at specified intervals in three discharge rates (1/2,1 and 2 gallons per hour). DURA-FLO^TM PC Dripperline is available in 100', 500', and 1,000' coils. Compatible plain tubing is available in 100', 500', and 1,000' coils.

Construction

DURA-FLOTM PC Dripperline shall consist of nominal sized one-half inch (1/2") inch linear low-density polyethylene tubing with pressure compensating, continuously self-cleaning, internally bonded emitters at a specified spacing, (12", 18" or 24" centers) or plain tubing without emitters. The tubing shall be brown, black or lavender in color and have an outside diameter (O.D.) of 0.700 inches and an inside diameter (I.D.) of 0.600 inches. Individual pressure compensating emitters shall be permanently bonded to the inside wall of the tubing. These emitters shall be constructed of polyethylene with a silicone diaphragm. The emitters shall also have dual outlet ports, ensuring that only one port has direct contact with the ground when the polyethylene tubing is on the surface.

Operation

The emitters shall have the ability to independently control discharge rates, with an inlet pressure of ten to sixty (10-60) pounds per square inch (PSI), at a constant flow and with a manufacturer's coefficient of variability (Cv) not exceeding 0.05. Recommended operating pressure shall be between 15-45 PSI. The emitter discharge rate shall be 1/2, 1, or 2 gallons per hour (GPH). The emitters shall include a turbulent path to create a pressure differential across a flexible diaphragm. The diaphragm will flex towards the outlet hole according to the pressure changes and restricts the out flow path thereby limiting variations in the flow rate. The dripperline shall be available in 12", 18" and 24" spacing between emitters unless otherwise specified. Maximum system pressure shall be 45 PSI. Filtration shall be 140 mesh for 1/2 GPH, 120 mesh for 1 GPH, and 80 mesh for 2 GPH emitters.
