How to choose a gear oil pump correctly

Thread Content

1. Based on the layout of the installation, terrain conditions, water level conditions, and operating conditions, determine whether to choose a horizontal, vertical, or other type of pump (such as pipeline-type, submersible, underwater, clog-free, self-priming, gear-driven, etc.). 2. For gear oil pumps, decide whether to use a single-suction pump or a double-suction pump depending on the flow rate; choose between a single-stage pump and a multi-stage pump, as well as between a high-speed pump and a low-speed pump (such as an air-conditioning pump), based on the required head. Multi-stage pumps have lower efficiency than single-stage pumps, so when both types are suitable, a single-stage pump should be preferred first. 3. Depending on the properties of the liquid medium, decide whether to use a clean water pump, a hot water pump, an oil pump, a chemical pump, a corrosion-resistant pump, or a pump designed to handle impurities; alternatively, a clog-free pump can be used. Pumps installed in explosive areas must use explosion-proof motors appropriate for the level of risk in that area. Original source: http://www.lingdoo.com/technology/2011/04-09/0445460.html
