Solidification of the liquid which remain inside the pump for the certain period of time causes damage to the connecting rod, diaphragms holding plates, valves. Fluids prone to solidification (such as ceramic pulps, glue, resins, tars, bitumen, sludge, etc.), which harden when exposed to oxygen in the air, solvent evaporation, water evaporation and temperature shouldn’t …
Dry running is a one of the key features that differentiate Air Operated Diaphragm pumps from other types of pumps. In majority of the cases this will not damage the pump, nor its elements. This is why, AODD pumps are often used in applications in which the fluid may unexpectedly run out (sumps dewatering, tanks …
Pneumatic Pump freezing is a result of thermodynamic adiabatic process in which change occurring within a system as a result of transfer of energy to or from the system in the form of work only. Freezing occurs inside the pump when the pressure of compressed air used to power the pump returns to the level …
In the second article from the cycle 12 ways how to kill your Diaphragm Pump I will concentrate on the ways how to handle Abrasive fluids. Abrasive fluids can be very destructive to the pump if not handle properly. They cause increased damage to the pump elements by gradually wearing away surfaces through physical force. …
This is the first article from the cycle – 12 ways how to kill your Diaphragm Pump. Contrary to the article title this is something, that nobody wants to do. In our articles we want to point out problems which may damage your pump, installation or significantly reduce lifetime of wearing parts. Diaphragm Pumps are …
