What Information Should a Pump Manufacturer Send to a VFD Supplier?

A pump manufacturer should send motor nameplates, supply details, pump applications, quantities, control requirements and installation conditions. This prevents a preliminary kW-based guess from becoming an incorrect production order.

What Information Is Required?

• Rated motor voltage, current, kW, Hz, rpm and motor type.
• Available input voltage, phase and frequency.
• Pump type, curve, flow, head and safe speed limits.
• Pressure, level, terminals, RS485 or multi-pump sequence.
• Temperature, altitude, enclosure and cable length.
• Annual demand, batch size, branding and target markets.

Selection Example

Instead of writing “need 4 kW VFD,” send a nameplate showing 380 V and 8.5 A, identify a centrifugal booster application, specify a 4–20 mA sensor and state the annual quantity. The supplier can then confirm current rating and control scope.

Common Mistakes

• Sending only pump kW.
• Omitting motor type or winding voltage.
• Failing to describe the sensor.
• Hiding high altitude or long motor cable.
• Mixing sample and production requirements.

AUSENIST Solution

AUSENIST can turn a complete data package into a YS620 or YS820 recommendation, initial parameters and OEM review list. Missing values remain assumptions until the pump manufacturer confirms them.

Send us your pump motor range, voltage, application and annual demand. We can recommend suitable VFD models, parameter settings and OEM solutions.
