The SMD - Efficient design for reliable distribution
Engineered for excellence
The workhorse of many water applications, the SMD is compliant with French ACS and US NSF 61/372 drinking water standards.
Multi-function design
The SMD can be engineered to meet all water applications including raw, clean, sea and brackish. We can adapt the design to meet your specific application criteria. Ideal for transport and pipeline applications, the SMD pump is designed to deliver extended reliability, even in more arduous conditions. Available as a standardized design or configured to a specific application, the SMD offers optimum performance.Discover the parts that makes perfect, press the hotspots
