Raw Water Intake Equipment

Our rich industry expertise also lies in successfully meeting the demands of Raw Water Intake Equipment. These comprise Travelling Water Screen, Stop Log Gate and Trash Rack. Here, our in-depth process knowledge allows us to deliver these in exact end specifications as demanded by the customers. The details include:

The Sluice offered by us share the same characteristics of versatility, durability, ease of installation and low maintenance.
Sluice gates are fluid control products that provide a mechanical means of controlling liquid flow through an opening in a variety of applications within the water and waste water industry. Our sluice gates meet and exceed the requirements of the IS standard for cast slide gates. Sluice gates can be of  cast iron or ductile cast iron. Sluice Gates have one-piece cast iron, Slides (covers) have horizontal and vertical ribs and cast side wedges. Fully adjustable, positive locking wedge blocks force the smoothly machined seats into a practical water  tight closure. Heavy galvanized structural steel guide angles and bolts are furnished as standard accessories. Stainless steel guides and bolts are optional and recommended for corrosive water conditions. Bronze seat facings should be specified where the gate will not be operated for long periods of time or where salt water, industrial wastes or sewage will be handled.

Slide gates are fluid control products that provide a mechanical means of controlling liquid flow through an opening in a variety of applications within the water and waste water industry. Our designed slide gates are fabricated aluminum or stainless steel with neoprene seals on two sides or two sides and top and a neoprene flush bottom seal at the bottom. This construction meets or exceeds the IS leakage standard. Adding J-seal to the unseating side will substantial reduce the unseating leakage even further. Slide gate designs are either self-contained or conventional and surface mount or embedded type. Slide gates can be open/close or modulating service.


We also meet the demands of Stop Log Gates that are used for blocking directed openings of lakes, rivers, canals and channels. These stop logs are supplied with all necessary parts with accessories.

For various objectives, the equipment provided is designed, fabricated, assembled, erected as well as installed in proper operating conditions in full conformity with:


  • Engineering data
  • Drawings
  • Specifications



We also hold expertise in meeting the demands of trash rack that are devices used to prevent trash as well as other debris from entering industrial raw water intake while not obstructing flow of water. These are presently utilized by major hydro electric, thermal, nuclear power generating facilities as well as water treatment plants throughout the world.

Here, the superior designing of the water inlets that is equipped with grates/other devices assist in collection of significant quantity of:


  • Floating debris
  • Litter and trash


We manufacture steel trash racks, that can be fully assembled & site engineered for location. These utilize engineering grade galvanized/ stainless steel, for achieving toughest and most durable bar screens that are available anywhere in commercial markets. Thus, the end result achieved is an incredibly strong, heavy-duty product that helps in saving money on repairs & maintenance due to its longevity.




  • Energy efficiency & capacity associated losses are avoided with presence of trash racks
  • Enhances units’ safety
  • Ensures reliability & availability by preventing down time associated with failures
  • Eliminates bio- fouling
  • Efficient water flow to turbines

Traveling Water Screen offered by us assist in meeting the demands of intake water screening which is of utmost importance for protecting downstream equipment like pumps and condensers from malfunctioning. These traveling water screens can be operated either continuously or intermittently, depending on the process requirements at client’s end. Further, as the water flows through screen, baskets typically made of MS/ SS/ fiber glass in varying size meshes along with endless band of screening baskets helps in removing the debris from moving water.


This, the debris collected on mesh panels is raised to deck level as well as are removed by back washing. The finer mesh screens can also be used for increased debris removal. The baskets, mounted to two strands of chain also allow smooth travel to top of the screen.

Having been used for decades, these water screens are successfully used in water intakes of:


  • Nuclear & thermal power stations
  • Steel works
  • Municipal and other industrial units



  • Completely eliminate debris carryover downstream of system
  • Ideal for high water volumes as well as heavy debris removal
  • Protection of down water equipment


Types of traveling water screens –


Broadly, traveling water screens are of two types:


  • Thru flow
  • Dual flow type


Having successfully executed various types of travelling water screens, these specially designed & commissioned stainless steel travelling water screens operate smoothly in inhospitable environment in open sea condition at:


  • Nuclear Power Corporation India, Tarapur Unit
