Engine monoset pumps are pumping systems that combine an engine and a pump in a single unit. They are mainly used in agriculture to lift and supply clear, cold water for irrigation, farming fields, and other rural water needs. These pumps are preferred because they are easy to operate, efficient in water delivery, and suitable for areas where electric power supply is limited or not reliable.
To ensure that these pumps perform safely and consistently, the Bureau of Indian Standards (BIS) provides certification under IS 11501:2023. This certification makes sure that these monoset pumps meet the required standards of quality, performance, and efficiency so they can work reliably under agricultural field conditions.
What is IS 11501:2023
This is the Indian Standard that defines the requirements for engine monoset pumps used for agricultural applications. The standard is issued by the Bureau of Indian Standards (BIS) to ensure that these pumping systems are:
- Built to deliver steady and efficient water flow for agricultural use
- Capable of performing reliably under long working hours in field conditions
- Strong enough to handle operational stress without breakdown or failure
- Designed for proper performance with accurate output and efficiency
- Tested to ensure durability, safety, and consistent functioning
Testing and Inspection Requirements – IS 11501:2023
To ensure reliable performance and long service life of these agricultural pumps, the Bureau of Indian Standards has defined strict testing and inspection requirements under the standards, which are carried out during manufacturing and quality checks.
What are R and S?
- R (Required): Test must be carried out in the manufacturer’s in-house laboratory
- S (Subcontracting Allowed): Test can be done in a BIS-recognized or NABL-accredited external laboratory
Physical and General Requirement Tests
- Dimensional Check (R) – Ensures correct size, alignment, and assembly of pump components
- General Construction Check (R) – Verifies overall build quality and design compliance
- Material of Construction Verification (S) – Confirms use of approved materials like gaskets, seals, and packing (IS 5120)
- Inspection of Components (R) – Ensures all parts meet required fitment and quality standards
Pump Performance Tests
- Head and Discharge Test (R) – Measures water delivery capacity at different heads
- Efficiency Check (R) – Ensures pump delivers expected output with proper performance
- Hydraulic Pressure Test (R) – Checks pump casing strength under working pressure
- Performance Guarantee Test (R) – Confirms compliance with specified operating conditions
Engine and Fuel System Tests
- Engine Performance Test (S) – Evaluates engine operation as per IS 11170 and IS 7347
- Fuel Consumption Test (R) – Measures fuel usage during operation under standard load conditions
- Speed and Output Verification (R) – Ensures correct RPM and rated power output
- Operational Stability Test (R) – Confirms smooth functioning during continuous use
BIS certification procedure for Monoset Pumps
The BIS certification process ensures that the product meets the required standard for proper and efficient operation as defined by the Bureau of Indian Standards (BIS). The process includes the following steps:
- Online Registration - Manufacturers register on the BIS Manak Online Portal by submitting company details, factory information, and product specifications. Foreign manufacturers must appoint an Authorized Indian Representative (AIR) in India.
- Testing at BIS-Approved Laboratory - Product samples are tested in BIS-approved laboratories to evaluate electrical safety, insulation resistance, heating efficiency, durability, and overall performance as per requirements.
- Application Submission - The application is submitted along with laboratory test reports, technical documents, manufacturing process details, and factory information. Foreign manufacturers must also provide AIR-related documents.
- Factory Inspection - BIS officials conduct an on-site inspection of the manufacturing unit to verify production processes, quality control systems, safety measures, and compliance with the standard.
- Grant of BIS License - If all requirements are successfully met, BIS issues the certification license under Scheme-I, allowing the manufacturer to produce and sell certified products.
- Use of ISI Mark After certification approval - The manufacturer is permitted to use the ISI mark along with a CM/L number on the product, confirming compliance with the standard.

Marking Requirements & License Validity
Marking Requirements
When a manufacturer obtains the BIS license, the ISI mark for engine pumps must be applied clearly and permanently on the product or its packaging. In addition to the ISI Mark, other important details must also be provided on the product or packaging, as specified in the table below. This ensures the product meets all quality and safety standards.
Note: Marking is typically applied using durable stamping, tagging, or permanent printing to ensure clear identification during handling, storage, and transportation, as per BIS marking requirements.
BIS License Validity for Engine Monoset Pumps
After getting BIS certification, the license is valid for a limited period. Manufacturers must follow BIS rules and maintain product quality to keep the license active.
License Validity Details
BIS Certification Cost for Engine Monoset Pumps
The cost of BIS certification includes charges for application, inspection, license, testing, and marking. These fees are paid to BIS as per Scheme I guidelines.
Note: As per actual As per actual
- Application fee for foreign manufacturers is payable via SWIFT (SAARC countries may pay in INR with applicable GST).
- Audit charges for foreign manufacturers vary based on country/location.
- Marking fee depends on the product category and production volume (MSME benefits may apply).
- Testing charges are paid directly to BIS-approved laboratories.
- Consultancy fees depend on product type and factory location.
