Product Overview

DC40C Series Two‑phase Brushless DC Circulation Pump – Industrial Grade Corrosion Resistant Submersible DC Pump

The ZKSJ DC40C is a heavy‑duty 2‑phase brushless DC circulation pump adopting magnetic isolation drive, equipped with optional PPO+30%GF corrosion resistant housing and IP68 full waterproof rating, supporting submersible & inline non‑self‑priming continuous operation. Available in 12V / 24V wide voltage versions, it covers max flow 720‑900L/H and max static head 4‑6M, with service life over 30,000 hours and running noise ≤40dB. Optional dry‑run/stall/water shortage protection and 0‑5V analog/potentiometer speed regulation, widely applied to EV auxiliary cooling, industrial liquid circulation, large aquarium, landscape fountain, PC liquid cooling and solar off‑grid projects.
