Centrifugal Regenerative Pumps are subject to mandatory BIS ISI certification under the Pumps (Quality Control) Order, 2026. From 6 mo after publication of the QCO in the e-Gazette, these products cannot be lawfully manufactured for sale, imported, or distributed in India without a valid BIS ISI licence under IS 8472:2019. Non-compliance attracts penalties under the BIS Act, 2016 — product seizure, fines, and prosecution.
This guide covers the applicable Indian Standard, key technical and safety requirements, the step-by-step certification process, documentary requirements, and the most common compliance pitfalls for manufacturers and importers.
📜 Applicable Indian Standard
- IS 8472:2019 — Centrifugal Regenerative Pumps (primary standard)
- Aligned with the corresponding IEC / ISO standard for technical performance and safety
- Latest amendments notified by BIS apply automatically
📌 Regenerative pumps deliver high head with small flow — making them ideal for boiler feed, high-rise plumbing, and lab applications. The QCO ensures consistent performance and reliable mechanical endurance.
🔬 Key Quality Requirements Under IS 8472:2019
BIS-approved laboratories evaluate the following during type testing:
High-Head Performance
Head and discharge at rated point per IS 8472 charts. Performance curve compliance across operating range.
Impeller & Casing
Side-channel impeller and casing material per IS 8472. Internal clearance retention under endurance testing.
Electrical & Sealing
Motor insulation, leakage current, earthing, and mechanical seal endurance. Thermal-overload protection verification.
Marking & Identification
Rated head, discharge, kW, voltage, and intended service. ISI Mark plus licence number on nameplate.
Products covered under IS 8472:2019:
- Boiler feed pumps for small commercial steam systems
- Domestic high-head pumps for high-rise residential plumbing
- Lab and pharma process pumps for low-flow high-head service
- OEM pump components in machinery and equipment
📋 Step-by-Step BIS ISI Certification Process
- Scope IdentificationList every kW rating, voltage, and head variant. OEM-embedded pump components also require separate certification.
- Application FilingSubmit online application on manak.bis.gov.in. Indian manufacturers via Product Certification Scheme; foreign manufacturers via FMCS.
- Sample TestingSubmit complete pump-and-motor sets to a BIS-recognised pump testing laboratory. High-head, efficiency, and endurance tests: approximately 4–6 weeks.
- Factory InspectionBIS officers inspect impeller machining, casing assembly, motor winding, and in-house testing capability.
- Licence GrantBIS issues the ISI Mark licence. ISI Mark plus licence number is applied on the pump nameplate.
- Surveillance & RenewalPeriodic BIS market sample testing, factory audits, and annual marking fees keep the licence active.
📄 Documents Required
- Company incorporation / registration certificate
- Product list with kW rating, head, voltage, service category
- Pump and motor engineering drawings and BOM
- Impeller and casing dimensional records
- Motor winding details and capacitor specifications
- Quality Manual / ISO 9001 certificate (if available)
- AIR appointment letter (for foreign manufacturers)
- Existing test reports from BIS-recognised labs (if any)
⚠ Common Compliance Pitfalls
Common issues include head shortfall after endurance testing, clearance widening from wear, mechanical-seal leakage, and incomplete nameplate marking of intended service.
🏭 Special Considerations for Importers
Regenerative pumps are imported for specialised applications — boiler feed, lab, and pharma. Each variant requires its own BIS ISI certification. OEMs embedding regenerative pumps in larger equipment must hold valid certification for the pump as a component.
