Frequently Asked Questions
Find answers to common questions about Johnson Screens technology and our water supply solutions.
What is Johnson Vee-Wire technology?
Johnson Vee-Wire is a world-class technology where a V-shaped profile wire is spirally wound around support rods. This creates a continuous slot opening that prevents clogging and allows for higher water discharge.
How does a Recharge Well work?
Recharge wells are used to replenish groundwater by directing surface water (often from rain) into the aquifer. Johnson Screens ensure this process is efficient by filtering out solids and reducing frictional head loss.
Why choose Stainless Steel over LCG?
Stainless Steel (SS-304/316L) offers superior corrosion resistance and is ideal for saline or chemically aggressive water. LCG (Low Carbon Galvanized) is a cost-effective alternative for moderate water conditions.
Are your products suitable for domestic use?
Yes, while our products are industrial-grade, they are perfectly suitable for domestic deep tubewells, housing societies, and rooftop rainwater harvesting systems.
Do you provide installation support?
As the sole distributor, we provide technical consultancy and guidance on the best product selection and installation practices for your specific project needs.
What slot sizes are available for V-Wire screens?
We offer a wide range of slot sizes ranging from 0.15mm to 3.00mm, allowing for precise control depending on the aquifer sand size.
Can Johnson Screens be used for industrial filtration?
Absolutely. Beyond water wells, our screens are used in food processing, pulp and paper, mining, and petrochemical industries for reliable solid-liquid separation.
What is the life expectancy of a Johnson Screen?
When properly selected for the water chemistry, a Stainless Steel Johnson Screen can last for several decades, often outlasting the life of the pump and the well itself.
How does the non-clogging feature work?
The V-shape opening widens inwardly. This means that any particle small enough to enter the slot will pass through without getting wedged, keeping the screen clean.
What is the benefit of a larger open area?
A larger open area reduces the entry velocity of water. This prevents sand from being pulled into the well, reduces encrustation, and lowers energy costs for pumping.
Is Haque Traders the only source for Johnson Screens in Bangladesh?
Yes, Haque Traders is the Sole Distributor of Johnson Screens in Bangladesh, ensuring you receive genuine products and expert technical support.
Do you offer customized screen designs?
Yes, we can customize the diameter, length, slot size, and material grade to meet the specific engineering requirements of your project.
