Start with the duty point, not the catalogue headline
Procurement comparisons fail when each supplier optimizes a different operating assumption. The duty point is the contract between hydraulics and economics: required flow, total dynamic head, water level behavior, and future expansion margin. Start there and force every bidder to map explicitly to the same declared envelope.
For borewell duty, include static and minimum water levels, casing diameter, and discharge pressure target. For openwell duty, clarify suction conditions and wet pit constraints. Export buyers should also include frequency, voltage variation behavior, and any mandatory efficiency framing used in tender evaluation.
Materials, water chemistry, and lifecycle realism
Water chemistry influences corrosion, abrasion, and seal life. Sand content accelerates wear in tight clearances; chlorides stress stainless grades differently depending on concentration and temperature. If chemistry is unknown, document the risk and specify a verification plan rather than guessing metallurgy from marketing names.
Serviceability matters: can wear parts be replaced without pulling the entire string repeatedly? Can the supplier provide a spares map aligned to your stocking policy? SUPERTECH WATER SOLUTION recommends RFQ submissions that include chemistry notes and maintenance access constraints so recommendations remain field-realistic.
Documentation discipline for EPC and government buyers
EPC and government evaluations reward clarity: consistent naming, tabulated performance references, and traceable material statements. Avoid ambiguous model codes that cannot be tied to a datasheet line item. Ask for commissioning checklists and protection settings assumptions in writing.
For export schedules, align documentation release gates to manufacturing release so customs and QA reviews do not become critical path surprises.
