What every machinery inspection covers
Machinery is bought on a datasheet. The buyer cannot see head, flow, leak tightness or free air delivery by looking at a crate, so most of the value of an inspection lies in watching the factory prove those numbers on units that were not hand-picked. Every machinery, pump or valve inspection runs these steps before the product-specific checks:
- Quantity and model mix against the purchase order, with serial numbers recorded for every unit inspected or tested.
- Drawing and datasheet check. Main dimensions, connection sizes, flange drillings, shaft and mounting dimensions, and materials named on the general arrangement drawing.
- Visual and workmanship. Casting surfaces, welds, machining marks, paint film thickness, fasteners, guards and cable routing.
- Witnessed tests. The factory runs its own performance, hydrostatic, seat-leak or electrical routine tests on units the inspector selects at random. The inspector records the readings, the instruments used and their calibration dates.
- Records. Material certificates to EN 10204 with heat numbers traced to the parts, calibration certificates, type-test reports and, for EU and UK buyers, the declaration of conformity and technical file.
- Marking and documents. Nameplates, CE or UKCA marking, rotation arrows, warning labels and the instruction manual in the buyer's language.
- Packing and loading. Preservation, blanking of open ports, skids and crates, and lashing in the container.
Visual and dimensional checks follow ISO 2859-1 sampling; see the AQL guide. Witnessed tests are usually on a fixed number of units agreed in the order, or on every unit for larger machines.
How the checklist changes by product
| Product | Main risk | What the inspector adds |
|---|---|---|
| Pumps | Head and flow below the guaranteed curve; motor insulation failure in submersibles | Witnessed performance test to the agreed ISO 9906 grade, casing hydro test, insulation resistance and high-voltage test |
| Industrial valves | Wrong body or trim material; seat leakage | Witnessed shell and seat tests to API 598 or ISO 5208, PMI on body and trim, wall thickness and marking |
| Air compressors | Free air delivery below the catalogue figure; receiver without valid certificates | Witnessed ISO 1217 delivery test, safety valve and receiver documents, noise label |
| Agricultural machinery | Missing guards; CE file that does not match the machine | Guarding against ISO 4254-1, function run, hitch dimensions, technical file review |
The parts that go into these machines have their own pages: iron castings for pump casings and gearbox housings, flanges and pipe fittings for valve ends and piping, and electric motors for motors bought on their own. The pump page covers the complete pump set, with the motor as part of it.
Witnessing tests: what we do and what we do not
Clear To Load does not own test beds, pressure rigs or a laboratory. Factories that make pumps, valves and compressors for export have their own, and the useful question is whether their results can be trusted. On site the inspector:
- picks the units to be tested from finished stock, not from a set the factory has prepared;
- checks that the gauges, flow meters, power analysers and test benches carry current calibration certificates, and notes the certificate numbers;
- watches the test from start to finish, records the raw readings and photographs the instruments;
- compares the results with the datasheet, the guaranteed point and the tolerance or acceptance grade written in the order.
Some checks need a qualified specialist. Radiography, ultrasonic flaw detection and other non-destructive tests are carried out by the factory's certified technicians or by an outside agency; our inspector witnesses them and reviews the reports. Where you need an independent NDT Level II technician or a welding inspector, appoint a certified agency and name it in the purchase order; our inspector can witness its work. For independent test results, we can send sealed samples to an ISO/IEC 17025-accredited lab through lab testing coordination. EN 10204 type 3.2 certificates must be validated by the purchaser's authorised representative or an inspector named by the relevant regulations; we can witness for you, but we do not issue 3.2 certificates. Our ISO/IEC 17020 accreditation is in progress.
Market rules that shape the checklist
| Market | Rule | What it means at the factory |
|---|---|---|
| EU | Machinery Directive 2006/42/EC until 19 January 2027; Machinery Regulation (EU) 2023/1230 applies from 20 January 2027 and repeals the Directive | Declaration of conformity, technical file, CE marking and instructions. Machines placed on the EU market from 20 January 2027 must meet the Regulation, so orders shipping late in 2026 need care about which text the declaration cites. See CE and UKCA marking |
| EU | Pressure Equipment Directive 2014/68/EU; Simple Pressure Vessels Directive 2014/29/EU | Valves and compressor receivers need the right conformity route; above the lower categories a notified body's number appears next to the CE mark |
| EU | Ecodesign Regulation (EU) No 547/2012 for clean water pumps (under review since 2018; confirm the current version) | Minimum efficiency index (MEI) and product information on the pump and in its documents |
| EU | Outdoor Noise Directive 2000/14/EC | Guaranteed sound power level label on compressors below 350 kW |
| EU | EMC Directive; Low Voltage Directive safety objectives | Electrical safety and EMC evidence for electric pump sets and compressors. See LVD and EMC |
| US and Canada | UL 778 for motor-operated water pumps; other UL standards by product | Listing mark and file number on the unit match the listing. See UL and ETL listing |
Under the new Regulation, instructions may be supplied in digital form, with a paper copy on request, and a short list of high-risk machinery categories needs a notified body. An inspector checks marks, nameplates and documents against the machine; whether a design meets the essential requirements is the manufacturer's and, where required, the notified body's decision.
Where pumps, valves and machinery are made in India
Engineering goods are made across India. We name a place only where an official or published institutional source supports it.
| Place | What the source says | Source |
|---|---|---|
| Coimbatore, Tamil Nadu | "The motor and pump industry supplies over 40% of India's requirements." The page also calls Coimbatore the pump city of Asia. The page was last updated in July 2018. | Coimbatore district website (coimbatore.nic.in), Economy page |
| Ahmedabad and Mehsana, Gujarat | Listed for power-driven pumps and for the submersible pump industry | Industries Commissionerate, Government of Gujarat, cluster development list |
| Rajkot, Gujarat | A "pump, foundry and diesel engine" cluster, and a separate foundry cluster | DC-MSME skill mapping sheet for Rajkot |
| Kolhapur, Maharashtra | The foundry cluster grew from local demand for agricultural machinery and oil engines; it now supplies mainly automotive castings, with pumps and valves among other users | TERI cluster profile for SIDBI, 2012 |
Department of Commerce TradeStat data put India's exports under HS 8413 (pumps for liquids) at US$1,604.8 million in FY2025-26, of which pump parts were US$670.9 million and centrifugal pumps US$451.1 million. The figures are provisional, and the heading also covers hand pumps, fuel pumps and parts, so they show scale rather than an exact count of the pumps buyers order.
Booking a machinery inspection
Clear To Load is based in Jodhpur, with inspectors in Jaipur, Saharanpur, Moradabad, Delhi NCR and Kolkata, and covers every city in India. An inspection costs US$249 per man-day. Coimbatore, Rajkot, Ahmedabad and Kolhapur are outside our inspector base cities, so travel there is charged at actual cost; see pricing.
For engineering goods, send the datasheet, general arrangement drawing, test procedure, the acceptance grade or tolerance you agreed, and the list of certificates you expect. A pre-production inspection can check castings and material certificates before machining. A during-production inspection is the right time to witness tests on the first units. A pre-shipment inspection then covers finished units, marking and packing, and container loading supervision covers lashing of crates and skids. The product pages below go into each type in detail.
