HEM® Hydrophore system
Designed with cutting-edge technology, it ensures reliable water supply with minimal space requirements and easy installation. The system features corrosion-resistant materials, multi-stage pumps, and redundancy measures for continuous operation in case of component failure.
Key Benefits:
- Compact design for minimal space requirements
- Quick and easy installation with two hydraulic couplings and one electrical connection
- Inlet and outlet manifolds permit left or right connections
- Constructed with 316 stainless steel for hydraulic assembly and all wetted pump parts
- Reliable multi-stage pumps with corrosion-resistant bearing sleeves
