pumps at various air flow rates and air injection depths at 100% submergence (level flow) in ponds, and concluded that 7.6-10 cm diameter pumps were the most practical. Centrifugal blowers are one of the most effective and inexpensive methods to produce or pump air because they produce relatively high volumes of air at low

Building your own airlift pump The Secret Life of the

Dec 29, 2013 The Airlift pump, sometimes called a mammoth pump. It is the easiest pump to make and you probably already have all the gear at home to build one. Invented around 1797 by Carl Emanuel Löscher. Just sharing the basic information with you all since

Air lift pump KSB

Air lift pumps are also known as mammoth pumps, gas lifts or Löscher pumps, and are used for lifting liquids laden with solids. For this purpose a gas is injected below the liquid level, via a compressor, into the pipe, which is immersed vertically into a liquid (also see Type of pump).. The function of air lift pumps is based on the lift action of a mixture of liquid and gas (see Two-phase
