The Berarma Atex Pumps<\/strong> are variable displacement vane pumps for use in potentially explosive atmospheres<\/strong>, CE marked according to ATEX Directive 2014\/34\/EU<\/strong> and available in the families PLPX<\/strong>, PHPX<\/strong> and PHPKX<\/strong>. PLPX are designed for low pressures (100\u2013120 bar), PHPX for high pressures (250 bar), while PHPKX integrate a constant power<\/strong> control device for medium pressures (180 bar). These series are characterized by quiet operation<\/strong>, high volumetric efficiency<\/strong>, long service life<\/strong>, modularity<\/strong> and energy savings<\/strong>; various mounting flanges<\/strong>, pressure\/flow controls<\/strong> and multiple pump coupling options<\/strong> are available.<\/p>\n

The ATEX pumps<\/strong> are variable displacement vane pumps for low or high operating pressures, equipped with a pressure control device that can be mechanical (PLPX), hydraulic (PHPX), or constant power (PHPKX), allowing the delivered flow to instantly adjust according to the circuit\u2019s demand.<\/p>\n

Variable displacement vane pumps are positive displacement pumps; therefore, they deliver a maximum flow rate equivalent to their displacement multiplied by the rotational speed.<\/p>\n

The operating pressure is generated by the pressure losses the fluid encounters along its path through the system. When the outlet pressure (in the system) reaches the pump\u2019s set pressure, the delivered flow automatically adjusts to the system\u2019s demand; once this value is reached, the pump reduces its flow rate down to zero while maintaining an almost constant pressure. Under zero-demand conditions, the pump only delivers oil to compensate for possible leakages and pilot flows.
\nThis series of pumps is certified for applications in potentially explosive atmospheres.<\/p>\n","protected":false},"featured_media":3565,"template":"","meta":[],"product_brand":[],"product_cat":[116,110],"product_tag":[316],"class_list":{"0":"post-3909","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-berarma-pumps","7":"product_cat-pumps-and-motors","8":"product_tag-berama","10":"first","11":"instock","12":"shipping-taxable","13":"product-type-simple"},"yoast_head":"\nPump ATEX Berarma -
