uPVC Column Pipes
Natraj uPVC Column Pipes are used in borewell systems to lower the pumpsets in the casing pipe to raise water.
Natraj uPVC Column Pipes are manufactured to sustain high tensile loads subjected on it by the weight of the Submersible Pumpset and vibration generated by it while running. These pipes have heavy duty square threads along with a separate socket attached to one end of the pipe. To ensure leak proof joints high quality EPDM rubber rings are provided on both ends of the pipe.
NATRAJ Submersible Column Pipes are available in sizes from 1 inch (25mm) to 4 inch (100 mm) ID & in standard 3 metre lengths. They are categorized under three categories SILVER (upto 100 ft), GOLD (100 ft to 200 ft), Diamond (200 ft to 350 ft) depending upon their depth of lowering.
Submersible Pump Link
Connects submersible pumps to surface delivery lines, helping lift borewell water safely and steadily.
Deep Borewell Lifting
Built to lift water from deeper borewells while supporting the load of the pump and pipe assembly.
Farm Borewell Systems
Column pipes lift groundwater from farm borewells to the outlet point before it enters irrigation pipelines.
Domestic Borewell Systems
Used in home borewells to raise water from submersible pumps to tanks and building supply lines.
Institutional Borewells
Supports water lifting for campuses, schools and institutions through dependable borewell pump and column pipe systems.
Submersible Pump Overhauling
Threaded column pipes help connect, lower, remove and service submersible pumps during borewell maintenance.
High Load Bearing Strength
Designed to support the suspended weight of submersible pumps and pipe strings, helping maintain dependable performance in deep borewell installations.
Strong Threaded Joint System
Precision threaded joints help connect pipe sections securely, supporting better alignment, reduced leakage risk and safer pump lowering.
Efficient Water Lifting Flow
Smooth internal surfaces help reduce friction loss, enabling steady water lifting from submersible pumps to the surface delivery line.
Corrosion Free Borewell Use
uPVC resists rust and corrosion in underground water conditions, making it suitable for long term borewell pumping applications.
Lightweight Pump Installation
Lightweight pipe sections are easier to handle, join, lower and remove during submersible pump installation and maintenance.
Durable Long Term Service
Built for dependable borewell operation, these pipes support continuous water lifting across domestic, agricultural and institutional use.
