Laing LOWARA D5-38/700B 12/24V D5-Vario D5 Series Pump
Lowara ecocirc D5vario (DC) – efficient circulation for development, prototypes and industrial applications
The Lowara ecocirc D5vario is a compact DC circulation pump for applications where high efficiency, quiet continuous operation and a robust service life are the top priorities. Thanks to the shaftless ball motor principle, the pump operates at virtually no noise, with low wear and, in practice, requires no maintenance—an obvious advantage for series products, test rigs and decentralized systems where access for service is limited. The D5 variant (ecocirc/Laing) is particularly interesting wherever liquids need to be circulated independently of the fixed power grid, or where a small but powerful DC pump is needed as a reliable functional module.
For developers & industry:
- Low power consumption reduces heat and load peaks—relevant for mobile devices, stand-alone systems and energy-optimized plant concepts.
- Quiet operation for labs & product integration: suitable for noise-sensitive environments (measurement points, medical devices, office/IT-near systems).
- Reliability for 24/7 use:
- Low-wear motor design, designed for continuous operation—helpful for continuous processes and unattended installations.
Easy tuning without complex control:
- The speed can be adjusted steplessly to the application—ideal for prototyping, variant management and field optimization.
Integrated safety function:
- Overtemperature protection ensures automatic shutdown in case of overheating and thus supports safety-oriented designs.
- Suitable for PV direct operation (ecocirc solar D5 / DC)
- The Lowara/Laing D5 is designed for direct operation with a photovoltaic panel.
- This makes it particularly attractive for stand-alone thermal solar systems,
- decentralized heat/cooling circuits without grid supply—applications where simple, robust power supply and automatic performance adaptation are required.
- Typical areas of application (focus: development & industry)
Thermal management & cooling:
- Cooling circuits in laser technology, power electronics, lab/analytical systems, medical technology or battery packs.
Test rigs & process engineering on a small scale:
- Circulation tasks in test setups, temperature-control circuits and demonstrators, where a compact DC pump must be quickly integrated.
Mobile and stand-alone heating/energy systems:
- Circulation in motorhomes, boats, off-grid cabins or temporary systems.
Water circulation in continuous operation:
- e.g. for domestic hot water circulation, storage and charging applications.
Aquaculture/pond/aquarium:
- Efficient continuous circulation with low energy demand.
