PN -type pump single-stage, single-suction, centrifugal mud pump, the material of pump flow components used wear-resistant alloy .
Model Code：
For example:2PN
2—Outlet diam.（The number of millimeters is 25 divided by the value）
P—Impurity pump
N—Mud pump
The maximum concentration of the delivery is 50-60% by weight.
Structure features：
1、Wet part with wear-resistant and corrosive-resistant cast iron, long service life。
2、Impeller and guard plate gap can be adjusted in time to maintain a high efficiency work.
3、≥4
inch pump,the pump bearing is directly in the horizontal open
bracket，Easy to adjust the demolition inspection in a timely manner, and
in the oil tank with water-cooled snake-like tube to improve the
bearing working conditions.
4、≥8 inch have big pump body,Using a
separate structure of the form, easy dis-assembly and maintenance.
Currently,our factory product PN and PNL mud pump mainly have about ten
types,such as：1PN、2PN、3PN、4PN、6PN、8PN、10PN、12PN,etc.In these
models，
