Six Reasons India's Industries
Rely on Us Year After Year
When critical bulk material feeding fails, the consequences ripple across your entire operation. Our clients choose Oswar because they know quality, reliability, and responsive service are non-negotiable.
Our engineering team has hands-on experience across cement, power, steel, mining, and pharma plants. We understand the specific feeding and metering challenges of each industry — whether it’s 300°C kiln gas or highly abrasive fly ash — and select materials and tolerances accordingly, not generically.
Every rotor and housing is machined to tight tolerances on CNC equipment. Rotor-to-housing clearances are set and verified to control material leakage and maintain metering accuracy. All castings are inspected for porosity and surface defects before machining.
Non-standard flange patterns, special port sizes, modified housing geometry, ATEX-rated versions, temperature-jacketed bodies — we handle all of these. If your feeding application doesn’t fit a standard design, our team creates a solution that does.
We stock rotors, seals, bearings, and end plates for all current and discontinued models. Emergency same-day dispatch is available for major industrial zones across India. Planned preventive maintenance kits are available as pre-packed assemblies.
Our service engineers travel to your facility for installation supervision, alignment checks, drive calibration, and first-run commissioning. This ensures your feeder performs from day one and that your maintenance team is trained on correct procedures.
No hidden costs. Our quotations include complete material specifications, testing scope, applicable standards, delivery lead time, and warranty terms — all in writing. We provide detailed test certificates, inspection reports, and O&M manuals with every supply.
