Almatec® AODD Pumps Upgraded With Electrically Conductive PTFE Diaphragms For Safer Chemical Transfer

Kamp-Lintfort, Germany, April 15, 2013 — Almatec®, a premier manufacturer of air-operated double-diaphragm (AODD) pumps specializing in plastic pumps with solid housings, is pleased to announced that its E-Series Plastic AODD pumps have been upgraded with electrically conductive PTFE (polytetrafluoroethylene) diaphragms to provide safer transfer of chemicals while avoiding dangerous electrostatic discharge. Pumps with non-conductive diaphragm materials can be susceptible to electrostatic discharge. Static can accumulate in liquid being moved or transferred through a non-conductive pump, leading to a sparking in a flammable vapor-air mixture. One common cause of electrostatic discharge occurs when the pump runs dry, which means the pump will continue to operate even after the chemical has been depleted. To prevent the pump from running dry, operators will have to insert nitrogen, water or carbon dioxide once the fluid transfer has been completed to avoid potentially dangerous electrostatic discharge. Almatec’s E-Series pumps equipped with conductive PTFE diaphragms can be used without risk in applications found in explosion-proof areas that involve flammable liquids. Thanks to the E-Series design and use of conductive materials in the construction of the pumps, there are no additional actions required for the prevention of dry running. This allows the Almatec E-Series pumps to meet the ATEX requirements for use in explosive or hazardous areas, enacted by the European Union. In addition to the added safety and security in hazardous applications, Almatec’s diaphragms have a large diameter and short stroke with low flexural load that ensures uniform delivery, regardless of the material used for the diaphragm’s construction.
