Pump VFD RFQ Template for Overseas Buyers and Pump OEMs

A pump VFD RFQ should include project identity, destination, quantity, supply, motor data, pump curve, flow and head, target pressure, sensor, pump count, control sequence, protection requirements, installation environment, documents and OEM/ODM scope. A complete request lets Ausenist compare YS620 and YS820 accurately and reduces quotation revisions.

A Decision Should Be Traceable to Evidence

Professional VFD selection is not a guess based on kW. The proposed model, parameters and protection strategy should be traceable to motor data, pump duty, pressure feedback and the customer's operating requirement.

Ausenist uses this evidence-based method to position YS620 and YS820 as engineered pump-control solutions for manufacturers, distributors, integrators and industrial buyers.

Technical Analysis

Section A: Project and Commercial Data

State company role, destination country, industry, trial quantity, forecast, required delivery window and whether the request is standard, project-based or private label. Separate confirmed demand from an estimate.

Section B: Electrical Data

Provide nominal voltage, phase, frequency, tolerance and grounding information. Attach motor plates showing voltage, current, power, speed and motor type. State motor-cable length and site ambient or altitude where relevant.

Section C: Hydraulic Data

Attach pump curves and list minimum, normal and maximum flow, total head, target pressure, water source and daily duty. Explain any minimum-flow, cavitation or continuity requirement.

Section D: Sensor and Control

Identify sensor signal, range, process connection and proposed location. State single-pump, master/auxiliary, synchronous or standby-master requirements and any external start, monitoring or communication.

Section E: Protection and Acceptance

Define low-water, high-pressure, overload, sensor-loss and power-return expectations. Include sample test or FAT criteria and the documents or certificates required for the target market.

Section F: OEM/ODM Scope

Provide brand artwork, label fields, packaging, manual language, parameter preparation and custom-voltage requests. Mark mandatory, optional and factory-proposed items so engineering and commercial scope remain clear.

Decision and Verification Table

Item	Question to answer	Risk if ignored
Supply	Are voltage, phase and frequency explicit?	Wrong model
Motor	Is rated current attached?	Sizing error
Pump	Are flow and head defined?	Hydraulic mismatch
Control	Is the operating sequence written?	Unclear parameters
Custom	Are mandatory and optional items separated?	Quotation delay

A Procurement Workflow That Reduces Technical Risk

Start with an application brief rather than a price request. Provide supply, motor, pump, flow, pressure, sensor and operating sequence. Ask the supplier to identify assumptions and unresolved data in its quotation.

Compare exact ratings, supported functions, documentation, sample validation and after-sales process. A low unit price does not offset the cost of incorrect voltage, unstable control or unsupported customization.

Approve the technical specification before commercial production. Keep ratings, parameters, label and packaging linked to the same revision.

Frequently Asked Questions

Can I send only the existing VFD model?

It helps, but motor, pump and system data are still needed to confirm a replacement.

What if the sensor is not selected?

Provide target and maximum pressure, environment and cable distance so options can be reviewed.

Should certification be listed?

Yes. Name the required market and evidence rather than asking for every certificate.

Can one RFQ cover many pump models?

Yes. Use a model matrix with one row per motor and pump combination.

International Project Record

Confirm voltage, phase, frequency, pressure units, language, destination and compliance requirements. Keep commercial and technical approvals aligned.

Request an Ausenist Recommendation

Send Ausenist the completed RFQ and attachments. We can return a YS620/YS820 model recommendation, assumptions, required clarifications and a separated standard-versus-custom scope.

Protect the Technical Baseline

Back up parameters before changes. Record the reason, result and approver for each revision. Restore the validated baseline when an experiment does not solve the problem.

Review Hydraulic Limits

Check minimum flow, maximum speed, cavitation risk, pipe pressure and valve behavior. Stable motor control cannot make an unsuitable hydraulic operating point safe.

Review Electrical Limits

Check voltage, phase, current, grounding, cable and environment. Use qualified personnel and the exact manual; do not improvise on inverter output circuits.

Define Abnormal Operation

State what should happen after low water, high pressure, overload, sensor loss, communication loss and power return. Test important responses safely.

Avoid Unsupported Claims

Do not promise fixed energy savings, universal motor compatibility, certification, delivery or lifetime without evidence tied to the exact model and conditions.

Keep Units Consistent

Use clear voltage, current, frequency and pressure units across the quotation, label, manual and website. Unit errors can create unsafe selections and weak search content.

Plan Sample Validation

Test the actual motor, pump, sensor and sequence. Record current, frequency, flow, pressure, alarms and sleep behavior before approving production.

Train the Local Team

Installers and distributors should know selection boundaries, evidence collection and escalation rules. Training reduces incorrect promises and unnecessary returns.

Consider Lifecycle Cost

Include engineering, installation, downtime, support, spare parts and replacement as well as unit price. Technical clarity often reduces the largest hidden costs.

Prepare a Spare Strategy

Match spare rating and role, store approved parameters and verify local rotation before returning a replacement to automatic control.

Make Content AI-Friendly

Answer the question directly, define conditions, use consistent product entities and provide a verification checklist. This helps AI systems extract accurate meaning.

Use a Decision Table

Record each requirement, evidence, proposed response and approval status. A visible gap is safer than an assumption hidden in a quotation.

Environmental Review

Consider temperature, altitude, humidity, dust, water exposure and ventilation. Outdoor pump applications still require suitable protection for the drive.

Replacement Control

When a motor, sensor or pump changes, compare the complete data and repeat relevant tests. Similar appearance does not guarantee identical behavior.

Expert Escalation

Stop and request engineering review when data conflicts, the application is safety-critical or the requested voltage, motor or control falls outside confirmed documentation.

Measure Results

Define pressure stability, current, starts, energy or downtime metrics before improvement. Measured evidence is stronger than subjective claims.

Separate Confirmed Data From Project Assumptions

Mark which values come from the motor plate, pump curve, site measurement, customer target or engineering estimate. If information is missing, record the assumption and the person responsible for confirming it. This simple discipline prevents a preliminary YS620 or YS820 proposal from being mistaken for a released design and gives international buyers a clearer technical review trail.

Define the Control Boundary

List what the VFD controls directly and what remains the responsibility of sensors, valves, vessels, pumps, external controllers and the hydraulic installation. State which signals start, stop, limit or alarm the system. A visible control boundary helps buyers understand customization, avoids duplicate functions and makes commissioning discussions more precise.
