Pump-Mounted VFD for Water Pump Manufacturers

AUSENIST provides compact pump-mounted VFD solutions designed for direct installation on compatible water pump motors.

Instead of installing every inverter inside a large electrical cabinet, the backpack-style inverter can be mounted directly on the motor junction box.

This design is especially useful for pump manufacturers developing integrated intelligent pump products.

Why Use a Pump-Mounted Inverter?

Traditional pump systems may require a separate control cabinet, additional wiring and more installation space.

A pump-mounted inverter can reduce these requirements.

AUSENIST product information describes the backpack-style design as suitable for direct installation on different pump motor junction boxes, reducing the need for large control-cabinet space.

For OEM manufacturers, this allows the VFD and pump to be supplied as a more complete integrated product.

IP54 Protection

The 620 and 820 intelligent pump inverter platforms use IP54 protection.

This provides protection suitable for pump environments where dust and moisture may be present.

IP54 protection also makes direct pump installation more practical than using an open general-purpose inverter.

Compatible with Different Pump Types

AUSENIST pump inverter solutions are designed for broad compatibility.

They can be applied to different pump brands and pump types, including centrifugal, booster, submersible and sewage pump applications.

This flexibility is useful for distributors and manufacturers offering multiple pump product lines.

PMSM and Induction Motor Support

The inverter platform supports both permanent magnet synchronous motors and conventional asynchronous induction motors.

This means one compatible inverter platform can be used for different motor technologies.

For pump manufacturers moving from induction motors toward high-efficiency PMSM designs, this can simplify product development.

Easier Operation

The 620 product documentation includes simplified functions such as one-button pressure adjustment and one-button factory reset.

Its installation process is also designed to be simplified for pump applications.

The objective is to reduce commissioning complexity for installers and end users.

Constant-Pressure Control

The pump-mounted inverter can also perform intelligent constant-pressure control.

PID control adjusts pump speed according to actual water consumption, while intelligent sleep operation stops unnecessary running when there is no water demand.

This makes the design suitable for integrated booster pumps and building water supply equipment.

Multi-Pump Capability

A compact pump-mounted design does not mean the inverter is limited to a single pump.

Compatible AUSENIST systems also support multi-pump control, including dual-master operation and auxiliary pumps.

This allows individual pump-mounted drives to form a coordinated water supply system.

OEM Benefits for Pump Manufacturers

For OEM manufacturers, direct pump mounting can provide several advantages: more compact finished products, less external wiring, easier assembly and a cleaner overall appearance.

AUSENIST also supports customization of branding, software, control parameters, PCB, hardware, enclosure, display, communication and packaging.

Frequently Asked Questions

Can the VFD be installed directly on a pump?

Yes. Compatible IP54 models use a backpack-style design for mounting on motor junction boxes.

Does it require a large control cabinet?

Direct-mounted configurations can reduce or eliminate the need for a large dedicated inverter cabinet, depending on the complete system design.

Does it support PMSM?

Yes. Compatible platforms support PMSM and induction motors.

Can it control constant pressure?

Yes. PID-based constant-pressure control is supported.

Can several pump-mounted inverters work together?

Yes. Compatible platforms support intelligent multi-pump operation.

OEM Pump-Mounted VFD

If you manufacture booster pumps or intelligent water pumps, send AUSENIST your motor dimensions, junction-box structure, power, voltage and application.

We can evaluate a suitable pump-mounted VFD configuration for your OEM product.
