When the pump is used to draw the liquid containing a lot of sharp particles, the Teflon diaphragm is easy to wear. Teflon diaphragm is provided with the advantage of resistance to strong acid and alkali

If the PH value is neutral, it is better to make use of SANTOPRENE wear-resistant diaphragm.

When the Teflon pump extracts paint, its diaphragm will wear due to long-term use. The flow of the pump will become small after the diaphragm is changed.

It is recommended to change the SANTOPRENE backup diaphragm beside the air chamber.

When the aluminum alloy pump draws the alkali sewage of PH>10 from the hardware factory, the ball cages be easily corroded.

It is better to make use of the stainless steel pump.

When the stainless steel pump is used to extract copper chloride + hydrochloride solution, it will produce "pitting" effect under the function of chloride ions. This is the currently main killer endangering the service life of stainless steel.

It is suggested to make use of the pure PP or PVDF pump.

The Y cup of air chamber in the pump easily wears, which causes the serious accumulation of dust.

It is recommended to increase three sources at the air inlet of pump.

If the outside diaphragm is damaged or the damaged diaphragm is not cleaned up after replaced by the new one, the long-term contact between the backup diaphragm and the paint will lead to deformation and shrinkage.

It is recommended to replace the SANTOPRENE backup diaphragm beside the air chamber.
