Diaphragm Pump - Characteristics

Characteristics

Diaphragm pumps:

• have good suction lift characteristics, some are low pressure pumps with low flow rates; others are capable of higher flow rates, dependent on the effective working diameter of the diaphragm and its stroke length. They can handle sludges and slurries with a relatively high amount of grit and solid content.
• suitable for discharge pressure up to 1,200 bar
• have good dry running characteristics.
• can be used to make artificial hearts.
• are used to make air pumps for the filters on small fish tanks.
• can be up to 97% efficient.
• have good self priming capabilities.
• can handle highly viscous liquids.
• are available for industrial, chemical and hygienic applications
• cause a pulsating flow that may cause water hammer
