GEA Hilge Centrifugal CONTRA Pump
Certified Safe Performance for your Demanding Processes – The GEA Hilge CONTRA range in the GEA Varipump line offers single or multi-stage, end-suction centrifugal pumps designed in accordance with the Qualified Hygienic Design (QHD) criteria and with EHEDG certification.
The pumps are CIP- and SIP-capable according to DIN EN 12462, meeting the world‘s highest hygiene standards. Apart from DIN, ASME and ANSI connections, a flexible range of custom connections is available upon request.
The pumps, furthermore, meet GMP requirements and use FDA-approved materials.
High Quality Throughout
The pumps are constructed with the use of deep-drawn and/or forged stainless steel materials in quality 1.4404 and 1.4435 (equivalent to AISI 316L), which guarantee a pore and blowholefree surface, as opposed to cast material.
The GEA Hilge CONTRA range pumps have open impellers, the multi-stages pumps also have open diffusors. The O-ring seal locations for the casing and impellers meet hygienic design criteria with metal-to-metal contact seal areas and no pump casing dead ends. The vertical versions of the GEA Hilge CONTRA pumps are fully self-draining through the suction port.
