Round / Cylindrical Dripper
A cylindrical emitter with a wide turbulent flow path, moulded on full hot runner tools for long life drip pipe.
RAL 5021 · semi-matt finishProduct introduction
How the Round / Cylindrical Dripper is engineered, and which sub-assemblies protect the performance your customers actually buy.
The cylindrical or round dripper is designed for drip pipe that stays in the field for several seasons. Its flow cross section is much wider than a flat dripper, which makes it far more tolerant of suspended solids and of root intrusion.
The dripper is moulded on a full hot runner tool with imported temperature control, which gives a clean, consistent part and a short cycle. Pressure compensating versions are available where the terrain or the length of the lateral makes compensation necessary.

Technical advantages
Every sub-assembly below is selected to protect the performance your customers buy.
Wide clog resistant channel
The turbulent flow path has a large cross section, so particles pass through instead of blocking the dripper.
Built for long service
A robust body and a wide channel suit pipe that stays in the ground for years.
Clean moulding
Full hot runner tooling with imported temperature control eliminates cold slugs and gives a consistent part.
Available with compensation
Pressure compensating versions hold a constant flow where elevation changes along the lateral.
Range of flows
One to eight litres per hour covers orchard, vineyard and row crop duty.
Consistent quality
Each batch is produced on a controlled mould with a defined cycle, so performance does not drift between deliveries.
Key benefits
- Wide clog resistant channel — The turbulent flow path has a large cross section, so particles pass through instead of blocking the dripper.
- Built for long service — A robust body and a wide channel suit pipe that stays in the ground for years.
- Clean moulding — Full hot runner tooling with imported temperature control eliminates cold slugs and gives a consistent part.
- Available with compensation — Pressure compensating versions hold a constant flow where elevation changes along the lateral.
Built to run
Material preparation, processing and downstream handling can be integrated into one turnkey scope from a single supplier.
Process flow
Each station is matched in capacity so the machine runs at the rated output without a bottleneck.
- Resin drying and dosing
- Injection into the hot runner mould
- Holding and cooling
- Ejection
- Vision inspection
- Bulk packing
- Feeding to the drip pipe line
- Insertion and welding into the pipe wall
Applications
Typical end uses for this product, based on the applications BENK MACHINE equipment already serves worldwide.
Orchards and vineyards
Permanent plantings where the pipe remains in position for years.
Long laterals
Blocks where friction loss along the line is significant.
Recycled water sources
Water carrying some suspended solids, where a wide flow path tolerates them.
Sloping ground
Sites where a pressure compensating version keeps the flow uniform.
Options and auxiliary equipment
Configure the machine for the market you sell into. Popular additions include:
- Colour coded caps per flow rate
- Custom flow rates on request
- Anti-drain and anti-siphon versions
- Bulk or boxed packing options

Why buy from BENK MACHINE
Extrusion specialists, not traders
BENK MACHINE designs and builds extrusion and drip irrigation equipment in Zhangjiagang with an in-house R and D and process team, so machine selection is matched to your resin and product instead of a catalogue number.
Evidence before shipment
Every machine is assembled and run in our works. You receive trial video, gauge and output records, and are welcome to attend the factory acceptance test.
Total cost, not lowest price
Energy efficient drives, permanent magnet motors and optimised heating reduce kWh per tonne, which usually matters more over five years than the initial purchase price.
Real commissioning support
Our engineers install, commission, train your operators and stay involved until the machine hits the specified output and quality on your material.
Spares and response
Critical spares are stocked for fast dispatch, and the Siemens Ethernet control platform allows remote diagnosis before a service visit is needed.
Upgrades as you grow
Co-extrusion, gauge control, automation and downstream equipment can be added later, protecting your original investment.
