BIS Certification for Horizontal Centrifugal Pumps (Agricultural & Rural) in India: Complete Compliance Guide

Horizontal centrifugal pumps for clear, cold water used in agricultural and rural water-supply applications require mandatory BIS ISI certification under IS 6595 (Part 1):2018.

Published: June 2026 Reading Time: 8 min Category: Product Compliance / Agricultural Pumps

Horizontal Centrifugal Pumps for Agricultural and Rural Water Supply 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 6595 (Part 1):2018. 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

📌 These are India's most widely used farm pumps. The QCO enforces minimum hydraulic performance, efficiency, and endurance — preventing low-quality pumps from undermining farmer water access and government rural water programmes.

🔬 Key Quality Requirements Under IS 6595 (Part 1):2018

BIS-approved laboratories evaluate the following during type testing:

Hydraulic Performance

Head, discharge, and efficiency at rated operating point. Performance curve compliance per IS 6595-1 charts.

Motor-Pump Integration

Coupling alignment, shaft endurance, and integrated-set vibration limits. Insulation and earthing on motor.

Endurance Testing

Continuous-duty testing at rated load for prescribed hours. Bearing and seal life within IS 6595-1 limits.

Marking & Identification

Rated discharge, head, kW, RPM, and motor details. ISI Mark plus licence number on pump nameplate.

📋 Step-by-Step BIS ISI Certification Process

  1. Scope Mapping (Part 1 vs Part 2)Confirm the pump is marketed for agricultural / rural use under Part 1 — not general use under Part 2. Mis-classification leads to test-report mismatches.
  2. Application FilingSubmit online application on manak.bis.gov.in. Indian manufacturers via Product Certification Scheme; foreign manufacturers via FMCS.
  3. Sample TestingSubmit complete coupled sets to a BIS-recognised pump testing laboratory. Hydraulic, efficiency, and endurance tests: approximately 4–6 weeks.
  4. Factory InspectionBIS officers inspect pump casting, machining, motor assembly, and in-house testing capability.
  5. Licence GrantBIS issues the ISI Mark licence. ISI Mark plus licence number is applied on the pump nameplate.
  6. Surveillance & RenewalPeriodic BIS market sample testing, factory audits, and annual marking fees keep the licence active.

Part 1 vs Part 2: IS 6595 (Part 1) covers agricultural / rural water-supply pumps. General-purpose pumps fall under IS 6595 (Part 2). Mis-classifying a model leads to BIS application rejection.

⚠ Common Compliance Pitfalls

Common issues include hydraulic performance below rated curves, efficiency shortfall, excessive vibration from coupling misalignment, and missing nameplate marking under IS 6595 (Part 1).

🏭 Special Considerations for Importers

Imported pumps targeting India's rural and agricultural market must hold valid BIS ISI certification under Part 1. Government and state-subsidy schemes require ISI marking as a vendor empanelment prerequisite.
