2.1. Dıaphragm runnıng temperature data
3.0. DIAPHRAGM PUMP DEFINITION
This diaphragm pump works with compressed air coming from a compressor. Pump working
principle is shown in the illustration below.
There are two valves distributing air in the pump. Outer valve is distributing the air to the
diaphragms. Inner air valve is rotating the outer valve.
Running a pump fast does not always mean working it most productively. If a pump
operates at highest capacity continuously, it will have diaphragm and valve problems
sooner. It is advisable to choose a higher capacity pump and it should not be used at
maximum pressure for long periods.
Diaphragm pump is mounted on the ground or on a tripod from its legs with bolts.
Air operated diaphragm pumps are suitable for transferring fluids up to 50,000 cP viscosity.
