Quanzhou Ausenist Technology Co., Ltd What Should OEM Pump Manufacturers Send for a VFD Quotation?
OEM pump manufacturers should send motor nameplate data, pump application, supply voltage, control method, quantity and cabinet requirements when requesting a VFD quotation. Clear information reduces wrong model selection and repeated engineering questions.
Recommended Configuration
| Item | Reference Selection |
|---|---|
| Motor Data | Power, voltage, current, frequency and wiring connection |
| Pump Data | Pump type, head, flow and duty |
| Control | Manual speed, PID pressure, level control or external command |
| Market | Local voltage, frequency and installation environment |
| Supply Scope | Drive only, parameter support or cabinet integration |
| Documentation | Nameplate photos, wiring request and application notes |
| VFD | AUSENIST pump VFD selected after data confirmation |
What Must Be Confirmed?
- Pump motor nameplate for each model in the range.
- Target market voltage and frequency.
- Whether the pump is booster, borehole, irrigation, HVAC, sewage or process duty.
- Required sensor inputs, relay outputs and user interface.
- Branding, parameter presetting or OEM packaging requirement.
- Estimated quantity, sample requirement and project timeline.
Selection Logic
For OEM projects, the same VFD family may be used across several pump sizes, but each motor still needs current verification. A quotation based only on pump model names can be risky because motor suppliers, voltage classes and rated current may change between markets.
The control function should be described in operational language. For example, “keep 4 bar pressure with a 4-20mA sensor” is clearer than “need automatic control.” “Start from tank low level and stop at high level” is clearer than “level control.”
If the OEM needs panel mounting, keypad access, parameter presetting, label support or documentation, these requirements should be stated early. They affect engineering review even when the VFD power rating is already known.
Common Mistakes
- Sending only pump power without motor current.
- Not specifying target market voltage and frequency.
- Mixing booster, borehole and sewage applications in one vague request.
- Asking for PID control without sensor range.
- Leaving OEM branding or packaging requirements until after pricing.
- Assuming one parameter file fits every pump model.
AUSENIST Solution
AUSENIST can support OEM pump manufacturers with VFD selection, application review and basic parameter guidance. Product details should be confirmed from existing AUSENIST data and selected model documents, without assuming unverified ratings or functions.
FAQ
What is the minimum information for a pump VFD quotation?
Send motor power, voltage, rated current, frequency, pump application, supply voltage, control method and quantity.
Why is motor current required?
Motor rated current confirms whether the VFD can carry the load. Power alone is not enough for final selection.
Should I send pump curves?
Yes if available. Pump curves help confirm pressure, flow, speed range and whether the requested control mode is realistic.
What should distributors send for stock selection?
Send common motor sizes, local voltage, main pump applications, expected quantities and whether customers need pressure control or simple speed control.
Can parameters be preset before shipment?
Basic settings may be prepared depending on the selected model and provided data. Final commissioning should still be checked on site.
Can AUSENIST support OEM pump panels?
AUSENIST can review drive and application requirements. Cabinet scope, wiring and accessories should be confirmed for each project.
What information should not be guessed?
Do not guess rated current, sensor type, IP rating, certifications, communication needs or warranty terms. Confirm them from actual documents.
