Day by Day water level is going down and creating alarming situation globally and agriculture consumes 70% of the water. To conserve natural resource and increase yield by irrigating more area with less water. Drip Irrigation System is the only solution. Our constant Endeavour is to give quality product with world class machine producing wide range of product to suit every crop and farmers requirement. Like 12MM & 16MM as per Indian Standard IS: 12786 Plain Coil, Online NPC/PC Dripper as per Indian Standard IS : 13487 flow rate 4/8/14 LPH for wider spacing and horticultural crops, 12MM & 16MM as per Indian Standard IS : 13488 Inline Round/Flat Drip line in Class 1, 2, 3 with flow rate 2, 3 and 4 LPH for closed spaced crops like sugarcane, cotton, Vegetables etc. We also manufacture required Fittings & Accessories used in Drip Irrigation System like PVC/PP Control Ball Valve, Flush valve, Screen/ Mesh / Disc filter, Sand/ Media filter, Strainer filter as per BIS IS : 12785 for effective filtration for clean irrigation water. Batteries of filtration unit for large fields also provided by us.
 
The advantages of Drip Irrigation are
  • Increase in yield in up to 40 to 50%.
  • Saves water up to 70%.
  • Fertilizer and nutrient loss is minimized due to localized application and reduced leaching.
  • Water application efficiency is high.
  • Field leveling is not necessary.
  • Fields with irregular shapes are easily accommodated.
  • Recycled non-potable water can be safely used.
  • Moisture within the root zone can be maintained at field capacity.
  • Soil type plays less important role in frequency of irrigation.
  • Soil erosion is minimized.
  • Weed growth is minimized.
  • Water distribution is highly uniform, controlled by output of each nozzle.
  • Labour cost is less than other irrigation methods.
  • Variation in supply can be regulated by regulating the valves and drippers.
  • Fertigation can easily be included with minimal waste of fertilizers.
  • Foliage remains dry, reducing the risk of disease.

Components of Drip irrigation
 
Emission Devices
On-Line Emitters
PVC Pipe
On-line Emitters 4/8/14 LPH as per BIS 13487 are small plastic devices with NPC/PC which convey small streams of flow from polyethylene (PE) tubing to the soil. Water then moves through the soil via capillary flow and creates a wetted circle, the size of which is dependent upon the soil type, flow rate and irrigation schedule. On-line emitters are attached to the PE tubing wall by inserting the emitter’s barb shaped base through a precisely punched hole. On line emitters offer the user the advantage of installing an emission device exactly where wanted, and if the emitter is “take-a-part”, it may also be serviced. The disadvantage is that the end user must manually insert each emitter. Although the ability to self-clean an emitter is an attractive feature, it should be viewed as an occasional event that is no substitute for proper filtration and maintenance. Drip irrigation systems may employ hundreds or even thousands of emitters, a quantity impractical to flush by hand.
 
In-Line Emitters / Drip Line
PVC Pipe
In-line Emitters or Drip line is the most advanced and precision product used in agriculture manufactured on world class machine, consists of small plastic emission devices similar in function to on-line emitters, but in this configuration they are pre-inserted into the PE tubing at specified intervals during the tubing extrusion process. The emitters may be cylindrical or flat and are attached to the inner tube wall of 12 MM or 16 MM as per Indian Standards 13488 via a controlled heating/adhesion process. It can be spaced between 2 dripper from 30 cm to 140 cm with a flow rate of 2, 3 or 4 LPH with NPC/PC dripper as per the crop requirement and land condition. Labor savings for the end user may be substantial since emitters are factory pre-installed. Unlike all other classifications of emission devices, drip line may be installed below the surface such that the soil surface may be kept dry and surface damage may be avoided.
Distribution System
 
Once the emission device is chosen, a system of filters, chemical injectors, pipes, valves and fittings must be constructed to deliver water reliably, safely and efficiently to each outlet, and to facilitate system maintenance. The major categories are as follows:
PVC Pipe

Filters

Filters are used to remove organic and inorganic debris from the water that could potentially clog the emission devices. In agriculture, sand media filters, screen filters or disc type filters are commonly used as per BIS IS : 12785 and may be cleansed manually, semi-automatically or automatically. Even where potable water is used, which is typical of landscaping applications, disc or screen filters should be installed since scale and chemical precipitants may occur which present a potential clogging hazard. Depending on the emission device chosen, the degree of filtration should be 80-200 mesh.
PVC Pipe

Chemical Injectors / Ventury 

Chemical Injectors / Ventury are typically installed in drip irrigation system in order to facilitate system maintenance with chlorine or acid, and also to supply nutrients or other liquid substances to the plants being irrigated. Whatever type of injector chosen, extreme care should be taken to ensure that the system includes proper safety and backflow prevention devices.
PVC Pipe

Pipe

PVC pipe as per BIS IS: 4985 is widely used to transport water from the water source to irrigation equipment of all types. In drip/micro-irrigation systems, it is typically used in the control zone and in the delivery network as both mainline and sub-mainline.
PVC Pipe

Tubing

PE tubing of 12 / 16 / 20/ 25 mm in Class-1 / 2 / 3 as per BIS IS: 12786 is widely used as the lateral pipe servicing the emission devices. Different wall thicknesses and reel lengths with varying pressure ratings and hydraulic characteristics with UV resistant.
Fittings
 
PVC pipe connections are typically made using solvent welded fittings, while PE tubing is usually barbed connection insert, or ring-lock type fittings.

Flush Valves

Flush Valves are used to periodically cleanse the conveyance and emission device components of organic and inorganic debris that could clog the emission devices if left unchecked. They may be simple manual valves fitted at the ends of mainlines, sub-mainlines and/or laterals, semi-automatic valves that flush only at start-up or shut-down, or fully automated solenoid valves.
PVC Pipe

Air / Vacuum Relief Valves

To avoid general equipment failure, pipe rupture or pipe blockage, A/V relief valves are used to expel air that builds up in the pipeline network during startup and operation. A/V relief valves are also used to allow air to enter the pipeline network as water exits at shutdown. This avoids undesirable vacuum suction in both the pipelines and the emission devices. A/V relief valves are typically installed at high elevation points, at control points, and at periodic pipeline intervals.
PVC Pipe

Pressure Gauges

Pressure Gauges are an essential item for drip systems since visual monitoring is often impractical or impossible. Pressure gauges placed at the pump station, before and after the filter station, and upstream and downstream of each control valve will provide an immediate indication of system performance. If pressures are too low, a leak could be indicated, a filter plugged or a valve jammed. If pressures are too high, the system could be plugged or a valve may be set incorrectly. Similar to a flow meter, accurate pressure information is essential part of a well-designed and operated drip system.
PVC Pipe

Control Valves

PVC / PP Control Valves are used to control the flow of water to the various blocks or network zones. They may be simple manually operated valves, or fully automated solenoid activated on/off or pressure reducing valves. They may be co-located at the pump station or other Point of Connection (POC), or may be dispersed throughout the farm.
