DML
WASTEWATER LIFT PUMPS
Description
Cast iron submersible pump with single-channel impeller that allows a free passage up to 76 mm, usable in fixed and mobile installations.
The DML - DMLF electric pumps stand out for their sturdiness and resistance, ideal for large applications and heavy-duty use.
