Booster pump requests that several factories can quote on one basis
Centrifugal Pump Sourcing coordinates a booster pump inquiry as a written duty, not as a promise that pressure will rise on site. The work is to restated ratings, quantity and delivery scope so two offers describe the same machine. We are an independent sourcing partner: we do not manufacture booster sets, do not hold listed stock, and do not commission piping or controls.
A booster pump in this family is usually a pressure-rise machine, often a multistage unit, sometimes an end-suction centrifugal pump with a different impeller trim. What must be on the request is the inlet pressure you already have, the discharge pressure you need, the flow in GPM at that rise, and the motor supply. Horsepower on a nameplate is not a substitute for that duty. HP and kW are related, yet they are not treated here as interchangeable quotation units; write whichever the factory uses and keep the other as a converted note if you must.
Voltage has to carry AC or DC, phase and frequency in Hz. A 230 V single-phase motor and a 230/460 V three-phase motor are different order lines even when the pump hydraulic selection looks similar. Full-load current stays in A. Do not place interrupting capacity (kA) or an SCCR figure on the pump line unless your panel builder asked for a listed combination and you can point to that combination's file.
Requirements, factory inquiries and quote comparison for booster pump programs. Installation, wiring and start-up stay with your contractor.
Responsibility range on a booster pump RFQ
Cost lines that often sit outside a factory pump price include freight to the destination, export packing, local listing files, a control panel, a variable frequency drive, suction and discharge fittings, and commissioning. Ask for those lines by name if you need them in the comparison. If two suppliers answer with different motor power, supply voltage or phase, we do not average the answers. We send the mismatch back and ask each factory to quote the voltage, phase and frequency you stated, or to mark the offer as an alternative with the electrical difference written on the first line.
| Task | Our role | Your role |
|---|---|---|
| Specification | Restate the booster duty, motor supply and missing fields | Approve the final spec, including HP or kW as written |
| Supplier selection | Shortlist factories for that duty and compare on one basis | Choose the supplier and commercial terms |
| Quality checks | Coordinate the inspections you named in the order | Accept or reject the shipment decision |
| Compliance | Collect the product documents the factory states for that model | Confirm destination rules, permits and installation |
Ingress protection and NEMA enclosure type, if a booster is supplied with a covered motor or outdoor hood, must be named as the system the factory uses. We will not write that an IP rating equals a NEMA type. Coil voltage belongs on the request when a starter, float or pressure switch is part of the same line. DIN rail accessories are listed only when they are in the bill. Selective coordination, residual current device settings and arc-flash labels are project electrical tasks, not pump-sourcing outputs.
When the hydraulic duty is still open, send pipe size, run length and the number of fittings rather than a guessed GPM. That is enough for factories to ask a clarifying question instead of inventing a curve point. Catalog forms live on the products page. Basement collection duties are framed on applications.
