By certification 
There are several types of mining submersible pumps.
Clarification by driven mode, there are electric motor driven and diesel engine driven.
Clarification by submersible section, electric deep well pump and single stage QW pump can be fully into the water and working under water surface. Another model is long shaft deep well pump, outflow 100m3/h to 1000m3/h, driven by motor vertically up the long shaft bop; driven by diesel engine via belt pulley or right angle gearbox because pump shaft vertically and engine shaft horizontally. Those pumps can meet different working conditions for water transfer or fire fighting as well as cleaning.

General possibilities of faults and solutions
Reasons and features | Solutions |
l. Fuel system | |
(1) Inner blocking | (1)Disassemble and wash |
(2) Air existed inner | (2)Clear air by manual fuel pump, check pipeline to clear leakages of fuel and air |
(3)Fuel pump does not supplyor intervally | (3)Check and repair |
(4)Bad moisture of injectors | (4)Check and adjust |
(5)Wrong advanced fuel supply angle | (5)Check and adjust |
2.Pressure not enough | |
(1)Worn piston rings and liners | (1)Check and replace |
(2)Piston rings with gum | (2)Clear |
(3)Air intake leakage | (3)Valve springs broken or weak,wrong valve gap.Bad seal,check and adjust |
| (4)Low temperature of compressed air | (4)Low surronding temperature.Preheating. |
| 3.Faults of electric units | |
(1)Batteries not fully charged | (1)Charge |
(2)Bad connection of wires | (2)Check and fasten |
(3)Starter not work or weak | (3)Check starter |
(4)Starter slip separation or reuinion | (4)check starter shaft connecting unit |
(5)Gears of motor Failure installing gear ring | (5)Find faults and repair |
