They provide the option to control the desired fluid flow rate by adjusting the volume of air that feeds the pneumatic motor. The particular <a href=\"https:\/\/www.debem.com\/en\/operation-diaphragm-pumps\/\" target=\"_blank\" rel=\"noopener noreferrer\">operation of the double diaphragm pumps<\/a> combined with the configuration and design characteristics brings the following application advantages within reach:<\/p>\r\n<ul>\r\n<li>Reliability and stability of pumping conditions<\/li>\r\n<li>Low air consumption volume<\/li>\r\n<li>Reduction of maintenance costs deriving from particular operating characteristics<\/li>\r\n<li>Ease of installation and flexibility when customising for different application needs.<\/li>\r\n<\/ul>\r\n<p>The particular construction configuration, thanks to the reinforcing support provided by the diaphragm, preserves the contact of liquids with the pneumatic mechanisms of the pump.

The two main types of materials that classify Debem Pumps are the following.<\/p>\r\n<h3>DEBEM PUMPS METALLIC MATERIALS<\/h3>\r\n<p>The metallic materials are Stainless steel and Aluminium, especially suitable for pumps used to pump and transport abrasive fluids, slurry, paints, inks, oils (even in case of solid processing residues), food and pharmaceutical fluids, glues, slip, biodiesel and for the construction industry, oil &amp; gas, mines.<\/p>\r\n<h3>DEBEM PUMPS PLASTIC MATERIALS<\/h3>\r\n<p>Plastic materials: Polypropylene with glass filler, Polypropylene with carbon filler, PVDF, which allow a degree of chemical compatibility with even highly aggressive fluids, both strongly acidic and basic, dyes for fabrics, chemical reagents, industrial detergents.<\/p>\r\n<h3>ATEX \u2013 IECEX CERTIFIED DEBEM PUMPS<\/h3>\r\n<p>Pumps designed for use in areas with a potential explosive hazard. All the plastics of these pumps are filled with carbon FIBRE to increase their conductivity level, preventing any electrostatic discharges from being generated. Be wary of imitations! Given the critical importance of using a pump in ATEX areas, make sure that the quality of the carbon fibre is of a high level. Debem ensures a conductivity of 100%, while the competition instead uses carbon powder and NOT fibre. Therefore the plastic is not actually 100% conductive. These pumps may cost less, but they are potentially dangerous and do not comply with the regulations.\u00a0<\/p>\r\n","protected":false},"excerpt":{"rendered":"Debem double diaphragm pumps enable to achieve high efficiency and reliability in terms of performance even under unfavourable environmental conditions.
