1、 Product overview

PN and PNL sewage mud pumps are horizontal and vertical single-stage single suction cantilever type impurity, mud pumps and sewage pumps, which have the following characteristics:

1. The clearance between impeller, pump body and guard plate can be adjusted in time to maintain high efficiency.

2. The pump is simple in structure, safe and reliable in use and convenient in installation. This type of pump can be used to transport sand, mud and sewage in infrastructure, geology, mining, smelting, environmental protection, chemical industry and other industries. The transport concentration is 50-60% by weight. Among them, 3pnl and 4pnl mud pumps are ideal equipment for drilling in basic construction projects.

2、 Model meaning

2pnl 2 - discharge diameter (the value obtained by dividing the number of millimeters by 25)

P - impurity pump

N - mud pump

L - vertical

4、 Technical characteristics

Flow: q7.2-320m3 / h

Lift: h14-50m

5、 Structural features

1. Wear resistant cast iron is used for wear-resistant parts of the overcurrent part, which has a long service life.

2. The clearance between the impeller and the guard plate can be adjusted in time to maintain high efficiency.

3. The bearing of the above pump is directly installed in the horizontal split bracket, which is convenient for disassembly and inspection and timely for adjustment. The water-cooled serpentine tube is installed in the oil pool, which improves the working conditions of the bearing.

4. The pump body above the pump is large and adopts the split structure, which is convenient for disassembly and maintenance.
