Sump Tanks About
WHAT IS A SUMP TANK?
A Sump Tank is an industrial storage tank or pit used to collect, settle, and temporarily store liquids, such as coolant, slurry, wastewater, oil-water mix, or filtrate, before they are pumped, filtered, or recirculated. It plays a key role in liquid handling and coolant recovery systems.
WORKING PRINCIPLE
- Liquid (e.g., dirty coolant, water, slurry) flows by gravity into the sump tank.
- The tank allows heavier particles to settle (sedimentation zone).
- Liquid may pass through baffles, strainers, or mesh filters.
- Cleaned or semi-cleaned fluid is pumped out using a submerged or external pump.
- Oil skimmer or filter units can be mounted to further separate oil and solid impurities.
TYPES OF SUMP TANKS

FAQ's of Sump Tanks:
Q: How are these sump tanks used in industrial oil filtration?
A: These sump tanks serve as critical components in industrial oil filtration systems by collecting and holding oil during the filtration process. Their sturdy design ensures efficient separation and containment of contaminated oil for optimal filtration outcomes.
Q: What are the benefits of using a sump tank with these specifications?
A: The tanks' durable construction, large capacity, and corrosion-resistant finish provide long-term reliability. Operating at 440V, they are equipped to handle demanding industrial environments, minimizing maintenance and improving equipment lifespan.
Q: When should I consider installing a new sump tank for oil filtration?
A: Installing a new sump tank is advisable when your current system cannot handle increased capacity, or when enhanced filtration efficiency is required. Upgrading can also be necessary if you notice frequent maintenance issues or reduced oil quality.
Q: Where are these sump tanks manufactured and supplied from?
A: These sump tanks are manufactured and supplied from India, with expertise in catering to the needs of industrial fabricators and suppliers across the region and beyond.
Q: What is the manufacturing process for these sump tanks?
A: Our tanks are fabricated from high-grade materials, welded for robust strength, and coated with RAL 7035 Appel Green for corrosion resistance. Strict quality checks ensure reliable performance before delivery.
Q: How do I choose the right size sump tank for my facility?
A: Selecting the appropriate size depends on your facility's oil filtration volume and space constraints. Options range from 900 to 1500mm in height and 600 to 1500mm in width and length, allowing you to match your operational needs.
