They have a long history of use in water and wastewater treatment and can also be found in food processing, pharmaceutical, and petroleum operations.<\/p>\n<p>Why such versatility? These metering pumps tend to be robust, working for long stretches between maintenance. They do not have internal components that rub against one another or cause friction. They also:<\/p>\n<ul>\n<li>Deliver high accuracy<\/li>\n<li>Handle viscous liquids<\/li>\n<li>Can achieve high pressures<\/li>\n<li>Typically offer good suction lift<\/li>\n<\/ul>\n<p>Diaphragm pumps are available in a wide range of control options. These include manual, analogue, flow proportioning, computer or PLC; ATEX versions are also available.<\/p>\n<p>Some PVC models are ideal for pumping sodium hydroxide or sulfuric acids in low concentrations, and hydrochloric acids in low concentrations.
