PN and PNL horizontal & vertical dredging pumps are single-stage single-suction types and are characterized by long service life, simple structure and reliable operation. The series pumps are primarily used to pump slurries and corrosive liquids that contain drifting sands and small-sized clods in the industries of mining, metallurgy, civil works, chemical, dyeing and printing. Also, the series pumps are used for pumping river mud, pond sludge, excrement, pasty liquid, ore sand liquid and slurry.

Max. saturation of liquid (as calculated by weight): 50%.

PN, PNL series pumps have seven types: 1PN, 2PN, 3PN, 4PN, 6PN, 2PNL and 3PNL.
