💧 ESPA DCV Submersible Electric Pump: vortex impeller for sludge and fibers
The ESPA DCV are three-phase submersible electric pumps made of GG25 cast iron, with an open, recessed vortex impeller and no wear rings. They are suitable for water containing large amounts of solids and long fibers, sewage with gas and sludge, as well as wastewater, stormwater, and drainage water.
🔩 Materials
- ✔ Body: made entirely of GG25 cast iron, with hardened and reinforced impellers
- ✔ Seals: double mechanical seals on most models, with CSi/ceramic on the pump side and graphite/steatite on the motor side
🧰 Equipment
- ✔ Sold separately: lowering and anchoring kit, support foot kit, bends, and protection and control panel
⚙️ Motor
- ✔ Motor: three-phase 400 V ± 10%, asynchronous, squirrel-cage rotor, class F insulation, IP68 protection
- ✔ Motor protection: provided by the user via the protection and control panel
📋 Operating Limits
- ✔ Temperature: maximum liquid temperature 40 °C
- ✔ Submersion: maximum 20 m
- ✔ pH: of the liquid between 6 and 10
- ✔ Solids: must not be larger than the free passage of the hydraulic section (see table)

🔤 How to Read the Model Numbers
- ✔ DCV4, DCV6: the number after the letters corresponds to the motor speed in the table: 4 = 1450 rpm, 6 = 950 rpm
- ✔ 80, 100: the first number is the discharge diameter (DN)
- ✔ 0037, 0058, 0125...: the last four digits indicate the motor power: 0037 = 3.7 kW, 0125 = 12.5 kW
- ✔ No M or A: they are three-phase 400 V models and do not come with a float switch
