Flow-regulated dripper DIAMOND

anti-drainagefor sloped terrainpressure-compensated

Short description
DIAMOND button drippers are pressure‑compensating, self‑cleaning emitters available in PC (Pressure‑Compensating) and PCND (Pressure‑Compensating Non‑Draining) versions. Self‑cleaning occurs at each start‑up, allowing free flow through the microchannel before compensation. The labyrinth geometry and star‑shaped inlet pre‑filter provide excellent resistance to blockage. Constructed from technical plastics with a silicone membrane for chemical resistance.

Features

• Pressure‑compensating, self‑cleaning design.
• Available in PC and PCND (non‑draining) variants.
• Labyrinth flow path with star inlet pre‑filter reduces clogging.
• High‑quality technical plastics and silicone membrane for chemical resistance.
• Compact emitter tube Ø5 mm compatible with microtube connection fittings (suitable for hydroponics).

Performance

• Nominal flows available: 2.2, 3.2, 4.0 and 8.2 l/h.
• Pressure compensation range and stable flow between 0.5 and 3.5 bar.
• Excellent coefficient of variation (CV) for uniform irrigation.
• PCND variant maintains pipeline charged for instantaneous on/off operation (recommended for short, high‑frequency irrigation).

Applications

• Suitable for long lateral runs and uneven terrain where uniform emitter flow along the line is required.
• Hydroponic crops: easy connection of mini‑tube and stake accessories to the Ø5 mm emitter tube.
• Short, high‑frequency irrigation using PCND to keep the line charged.

DIAMOND dripper description (expanded)
DIAMOND is engineered for consistent discharge under varying pressures. At each start, the emitter permits free flow through the microchannel area to perform self‑cleaning before pressure compensation engages. The emitter’s internal labyrinth and star‑shaped inlet pre‑filter minimize clogging from particulates and irrigation chemistry. The compact Ø5 mm outlet tube allows direct connection to microtubes for localized delivery in greenhouse and hydroponic setups.
