Pressure Compensating Drip Pipe Production Line
A line for inline pressure compensating drippers that hold a constant flow rate as pressure varies along the lateral.
RAL 5021 · semi-matt finishProduct introduction
How the Pressure Compensating Drip Pipe Production Line is engineered, and which sub-assemblies protect the performance your customers actually buy.
A pressure compensating dripper contains a silicone diaphragm that deforms as line pressure rises, closing the flow path just enough to keep the discharge constant. The result is a lateral that delivers the same flow at the first and the last dripper, even on long runs or sloping ground.
Pressure compensating pipe is specified for high value crops and for terrain where a conventional dripper would over-irrigate the top of the block and under-irrigate the bottom. The line is built around a heavy wall extruder, a high precision insertion unit, servo punching and full online inspection, and many designs are self-cleaning and anti-siphon.

Technical advantages
Every sub-assembly below is selected to protect the performance your customers buy.
Constant flow under varying pressure
The diaphragm compensates automatically, so every dripper discharges the same volume along the lateral.
Ideal for long and sloping runs
Compensation removes the need to shorten laterals on undulating blocks or long runs.
Self-cleaning design
The turbulent flow channel and precision inlet filter flush debris through the dripper during operation.
Anti-drain and anti-siphon options
On anti-drain models flow stops at low pressure, which prevents soil from being drawn back into the dripper.
High precision insertion
The insertion and welding station is servo controlled, holding emitter spacing and orientation within tight limits.
Full inspection
Perforation quality and dripper spacing are checked online, with automatic correction available.
Key benefits
- Constant flow under varying pressure — The diaphragm compensates automatically, so every dripper discharges the same volume along the lateral.
- Ideal for long and sloping runs — Compensation removes the need to shorten laterals on undulating blocks or long runs.
- Self-cleaning design — The turbulent flow channel and precision inlet filter flush debris through the dripper during operation.
- Anti-drain and anti-siphon options — On anti-drain models flow stops at low pressure, which prevents soil from being drawn back into the dripper.
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 dosing and blending
- Heavy wall extrusion
- Die head and vacuum sizing
- PC dripper feed and orientation
- Dripper insertion and welding
- Servo punching
- Full online inspection
- Automatic winding and packing
Applications
Typical end uses for this product, based on the applications BENK MACHINE equipment already serves worldwide.
Sloping and hilly fields
Blocks with large elevation change where pressure varies along the lateral.
Long lateral runs
Fields where laterals are long enough that friction loss would otherwise matter.
High value crops
Orchards, vineyards, berries and vegetables where uniformity directly affects yield.
Buried installation
Subsurface drip where the dripper must resist root intrusion and back siphonage.
Options and auxiliary equipment
Configure the machine for the market you sell into. Popular additions include:
- Automatic reel change robot
- Online optical inspection with auto correction
- Gravimetric blender with extrusion process control
- Bimetallic screw and barrel
- Melt pump for stable pressure
- Remote maintenance and fault diagnosis
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.
