💧 ESPA DCM Submersible Electric Pump: cast iron, single-channel impeller
The ESPA DCM are three-phase submersible electric pumps made of GG25 cast iron for urban and industrial wastewater, stormwater, drainage, and sewage containing solids. The single-channel impeller provides a wide passage and reduces the risk of clogging. The table shows the speed, power, and solids passage for each model.
🔩 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
- ✔ 90° bend: included
- ✔ Cable: 10 m, without plug
- ✔ 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: the user's responsibility, 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 in the hydraulic section (see table)

🔤 How to Read the References
- ✔ DCM2, DCM4: the number after the letters corresponds to the motor speed in the table: 2 = 2850 rpm, 4 = 1450 rpm
- ✔ 65, 80, 150: the first number is the discharge diameter (DN)
- ✔ 0020, 0046, 0125...: the last four digits indicate the motor power: 0020 = 2.0 kW, 0125 = 12.5 kW
- ✔ Without M or A: these are three-phase 400 V and do not include a float
