Description
Our detachable pressure compensating dripper is a precision-engineered emitter that delivers consistent water flow across varying terrain and pressure conditions. The device uses an elastic silicone diaphragm that automatically adjusts the outlet section in response to water pressure changes, ensuring uniform effluent distribution regardless of pressure fluctuations. This technology addresses common irrigation challenges in fields with elevation changes or long lateral lines.
Standard flow rates are 2 L/h, 4 L/h, and 8 L/h, with color-coded identification (Yellow, Black, Blue). Custom flow rates are available upon request. Connection types include 1/4" standard, with custom options available. Packaging options include bulk or retail packaging to meet different commercial procurement requirements.

Product Features
The dripper utilizes an elastic silicone diaphragm that automatically adjusts the outlet section based on water flow pressure. This mechanism maintains consistent flow rates across the working pressure range of 100-350 kPa. The pressure compensation range extends from 0.05-0.40 MPa (0.5-4.0 bar), accommodating variations caused by terrain elevation changes or system pressure fluctuations.
The detachable construction allows inspection and cleaning without removing the dripper from the irrigation line. This design reduces maintenance time and helps maintain performance over time by allowing operators to clear debris that may accumulate.
Manufactured from engineering plastic with anti-corrosion and anti-UV additives, these drippers maintain structural integrity when exposed to agricultural environments, fertilizers, and sunlight. The materials are selected for long-term performance in outdoor conditions.
These drippers can be connected with 5mm or 7mm PVC hose, or installed directly on PE pipes by punching. This versatility accommodates various system designs and simplifies integration into existing irrigation networks.
Product Uses
These drippers serve multiple agricultural applications. They are used in orchards for tree crops including apples, citrus, almonds, and olives. In greenhouses, they support vegetable production where uniform water and nutrient delivery affects crop quality and yield. The detachable design facilitates cleaning in environments where algae may be present.
Additional applications include gardening and landscaping, sloping terrain, vineyards, field crops, and container nurseries. The pressure compensation capability makes these drippers suitable for hillsides and sloping fields where standard drippers would experience flow variation due to elevation pressure differences.
FAQ
Pressure compensation automatically adjusts the dripper's outlet opening to maintain constant flow across varying pressures. This ensures each plant receives the same amount of water regardless of pressure differences caused by elevation changes, friction loss, or varying system pressure.
The working pressure range is 100-350 kPa (1.0-3.5 bar). The dripper maintains consistent flow throughout this range.
Available flow rates are 2 L/h, 4 L/h, and 8 L/h, with color coding for identification: Yellow (2 L/h), Black (4 L/h), Blue (8 L/h).
The detachable design allows cleaning – depressurize the system, detach the dripper, open the housing, rinse internal components with clean water, and reassemble.
Minimum filtration of 120 mesh is required to prevent debris from entering and clogging the drippers.
