Lowara DN Submersible Drainage Pumps (Cast Iron + Rubber)

The historic, abrasion-resistant pump for excavations, ditches and sandy water

The Lowara DN series is a classic in professional drainage. Unlike modern pressed steel pumps, the DN maintains a robust construction with a cast iron body and an impeller coated in wear-resistant rubber.

This unique combination makes it the number one choice for:

• Abrasive Water: The presence of sand, earth, or construction debris wears out standard pumps. The DN, thanks to its rubber coating, resists abrasion much longer.
• Excavation Drainage: Perfect for draining muddy construction excavations or agricultural ditches.
• Maintenance over time: The (front) skid plate is rubber-coated and adjustable, allowing hydraulic performance to be recovered even after years of intense wear.

Why choose Lowara DN instead of DIWA or DOC?

While the DOC (light stainless steel) is for domestic use and the DIWA (heavy stainless steel) is for modern construction sites, the Lowara DN is specifically for those looking for the repairability and mechanical resistance of cast iron.

• Cast Iron Body: Heavy and stable, it does not move if the pipe "pulls".
• Rubberized Open Impeller: Allows the passage of small solids (up to 5mm) and protects metal parts from the "sandpaper" effect of the sand.
• Protected Mechanical Seal: The seal (Carbon/Ceramic) is housed in a protective labyrinth that keeps sand out, extending its life.

Recommended Applications

Don't use it for sewer drains (it will clog). Use it for:

• Draining rainwater collection pits with soil residues.
• Flood irrigation from canals or ditches.
• Emptying of light sludge settling tanks.
