The energy a pump consumes during operation tells only part of its efficiency story. Material use during manufacturing, maintenance requirements and service life are equally important considerations. With the D43 series, Hendor has addressed these aspects through more efficient production methods, a maintenance-friendly design and optimised hydraulics.

A different approach to pump development

Developed as the successor to the D30 series, the D43 reflects Hendor's approach to improving pump performance while considering resource use throughout the product's lifecycle.

The development process focused on reducing material waste, simplifying maintenance and supporting efficient operation. The result is a series of vertical immersion pumps designed for industrial applications such as fume scrubbers and powder coating pre-treatment installations.

Available in two configurations, the D43-400 and D43-600, the series combines practical installation features with a robust construction designed for long-term operation.

This approach is part of Hendor's broader Smart Technology for Future Generations philosophy, which connects technical product development with the responsible use of resources.

Reducing material waste during manufacturing

One of the most significant improvements made during the development of the D43 series was a reduction in production waste.

By optimising its manufacturing processes, Hendor reduced material waste from 65% to 5%. This improvement demonstrates how changes in production methods can substantially reduce unnecessary material consumption while maintaining the quality required for industrial pump applications.

For Hendor, efficient pump development therefore extends beyond operational performance to include the resources used to manufacture the equipment.

Engineered to minimise maintenance

The D43 series features a sealless cantilever design without submerged bearings. By eliminating mechanical shaft seals and bearings in contact with the pumped liquid, Hendor has removed components that would otherwise be exposed to wear during operation.

The pump is also designed to operate safely under dry-running conditions, providing additional operational security when liquid levels fluctuate.

An oversized motor shaft and robust motor bearing arrangement support stable operation and long service life.

Together, these design choices help limit maintenance interventions and reduce the risk of unplanned pump-related downtime.

Efficient hydraulics for long-term operation

The D43 series incorporates optimised hydraulic components designed to support efficient liquid circulation. Combined with efficient motors, this construction helps limit the energy required to deliver the necessary pump performance.

Where process requirements vary, optional frequency control allows the pump's operating speed to be adjusted to actual demand. This makes it possible to avoid unnecessary energy consumption when full pump capacity is not required.

For continuously operating industrial installations, matching pump output to process requirements can contribute to lower operating costs over time.

Practical design for machine builders

The D43-400 and D43-600 offer different immersion lengths, providing flexibility when integrating pumps into tanks and industrial equipment. The extended configuration of the D43-600 can support more compact tank designs where installation space is limited.

A round mounting flange facilitates installation, while the accessible construction simplifies removal and disassembly when servicing is required.

With flow rates of up to 180 m³/h, the series offers a solution for liquid circulation in industrial scrubbers and powder coating pre-treatment installations.

These features help machine builders incorporate reliable pump technology into their equipment while considering future maintenance requirements.
