PN Mud Pump

PN mud pump product introduction

PN type mud pump is single stage, single suck, horizontal centrifugal mud pump, this type pump flow components is wear-resistant alloy materials manufacturing. Impeller and guard board clearance can adjust to maintain efficient work. 6 inches below the pump type with threaded connection, impeller 8 inches above pump type from the key link. Shaft seals use packing seal, work should be injected higher working pressure 1kg/cm2 shaft seal water. The pump has simple structure, reliable, simple maintenance and long service life etc. Suitable for mining conveying solid-liquid two-phase fluid with, conveying maximum weight for 50-60% concentration.

PN mud pump structure feature

1.Reasonable structure, convenient repair: pump head part is used for before and after the door structure, repair without dismantling piping, just move the motor backwards, can be disassembled and repair the pump.

2.High concentration, no clogging: conveying pulp concentration up to 6%;

3. Cavitation erosion resistance, long service life: the actual service life than ordinary paper pulp pump can be increased by 2-3 times;

4. High efficiency, energy saving: efficiency than ordinary pulp pump average of 3-10 percentage points, saving energy and reducing consumption, up to 15-30% .

5.The impeller and the guard board clearance can be adjusted in a timely manner, maintain higher working efficiency. The pump above the pump body is larger, the structure of open, disassembly and convenient maintenance.

PN mud pump structure and type meaning

PN slurry pump, composed of 10 parts: the pump body, cover,impeller, guard board, packing box, shaft bracket, bracket, rear cover, cooling pipe, a pump seat. PN mud pump model significance: such as 2PN mud pump 2-- spit out diameter (mm number divided by 25 income value) P--- impurity pump N--- mud.

PN mud pump application and scope

1.PN type slurry pump single stage single suction pump (vertical,horizontal) has the characteristics of long service life, simple structure, reliable running etc.. Delivers maximum concentration by weight is 50%.

2. Used in mining, metallurgy, municipal construction, chemical industry, printing and dyeing and other suction flow sand, mud,muddy small mud liquid with.

3, In the countryside, the mud pond mud fluid, feces, pulp beverage suction; can also be used for City factory transport ore fluid,underground suction sand and mud, yellow.

PN mud pump structure using the matters needing attention

(1) The disassembling and assembling according to the assembly diagram.

(2) A pulp inlet pipe should not be anxious brush bending, as far as possible downward sloping (DIP 30 °), easy to exhaust.

(3) Should grasp the running period of regular replacement of spare parts and bearings to prevent accidents.

(4) Into the slurry is too small not to run, so as not to cause vibration and slurry precipitation.

(5) Application of water rinse to prevent clogging the pump is stopped.

(6) The type of pump in addition to 12PN mud export level, others are vertical upward.

(7) PN type pump shaft seal water must be added a certain amount of water, the general work flow of 1-3%, the pressure should be greater than the working pressure of 1 kg / cm 2.

(8) 1PN, 2PN, 3PN, 2PNL, 3PNL steering motor direction is clockwise, 4PN, 6PN, 8PN, 10PN, 12PN steering motor direction is counter clockwise.

(9) In this type of pump in general use.

(10) The pump is not allowed to reverse parking.
