Water Pump Applications

Our VFDs are used for:

• Constant pressure booster pumps
• Residential water supply
• Commercial water supply
• Irrigation systems
• Agricultural pumps
• Water treatment systems
• HVAC circulation pumps
• Industrial centrifugal pumps
• Cooling water pumps
• Pump stations
• Process water systems

The inverter automatically adjusts motor speed according to actual demand.

For constant pressure systems, pressure feedback can be received through a pressure sensor using 0–10V or 4–20mA signals.

When water demand increases, pump speed increases.

When demand decreases, pump speed decreases.

This helps provide stable pressure while reducing unnecessary full-speed operation.

Support for Induction Motors and PMSM

Our inverter solutions support both conventional asynchronous motors and permanent magnet synchronous motors.

Pump manufacturers can provide motor nameplate information, including motor power, voltage, current, speed and frequency.

Our engineers can help configure the appropriate control solution.

RS485 Modbus Communication

RS485 with Modbus RTU allows the inverter to communicate with:

• PLC systems
• Pump control panels
• SCADA systems
• Building management systems
• Central monitoring systems
• Water treatment equipment
• Industrial automation systems

IP20, IP54 and IP65 Options

Different pump applications require different environmental protection.

Ausenist provides IP20, IP54 and IP65 inverter solutions.

IP54 and IP65 models are suitable for applications requiring improved protection against moisture and dust.

Combined with an operating temperature range from -40°C to +60°C, our inverter solutions are suitable for demanding international applications.
