2. Sewage pumping - Wikipedia

   en.wikipedia.org/wiki/Sewage_pumping

   Larger submersible pumps, handle 65 millimetres (2.6 in) and larger solids and normally have a minimum of 80 millimetres (3.1 in) discharge. They are generally used in municipal and industrial applications for pumping sewage and all types of industrial waste water.

3. Pressure sewer - Wikipedia

   en.wikipedia.org/wiki/Pressure_sewer

   The discharge pipe may be as small as 50 mm diameter carrying sewage at very high flow rates. [2] Pressure sewers are also used to collect the discharge from septic tanks and discharge this into the local gravity sewer to protect local ground water from contamination. [3]

An airlift pump is a pump that has low suction and moderate discharge of liquid and entrained solids. The pump injects compressed air at ...

5. Drain-waste-vent system - Wikipedia

   en.wikipedia.org/wiki/Drain-waste-vent_system

   A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.

6. Water pumping - Wikipedia

   en.wikipedia.org/wiki/Water_pumping

   The coil pump, if fitted with a suitable rotating seal, can deliver water to a greater height, typically 5-10m, above their discharge opening. [2] Despite the emergence of new pumps that operate on other principles, the coil pump remains an important tool as some of it other benefits are that they can be built and repaired easily at a very low ...

7. Axial-flow pump - Wikipedia

   en.wikipedia.org/wiki/Axial-flow_pump

   An axial-flow pump for industrial use. An axial-flow pump, or AFP, is a common type of pump that essentially consists of a propeller (an axial impeller) in a pipe.The propeller can be driven directly by a sealed motor in the pipe or by electric motor or petrol/diesel engines mounted to the pipe from the outside or by a right-angle drive shaft that pierces the pipe.
