PEDROLLO BC 35 Double-Channel Submersible Pumps
DOUBLE-CHANNEL
- BC electric pumps are DOUBLE CHANNEL pumps, specially designed and made using the most advanced expertise of Pedrollo that can rely on 50 years of experience in pump construction.
- Made from stainless steel and exceptionally sturdy, abrasion-resistant, long-lasting, heavy-gauge cast iron, BC series pumps feature high-efficiency DOUBLE CHANNEL type impellers for high flow rates. They are therefore suitable for draining foul and waste water, sewage, water mixed with solids, activated and putrid sludge with solids in suspension up to 50 mm in diameter.
