Title (EN) SQUARE, HERMETICALLY SEALED, DOUBLE-ACTING DUPLEX PUMP
(FR) POMPE CARRÉE HERMÉTIQUE DUPLEX À DOUBLE ACTION
(PT) BOMBA QUADRADA HERMÉTICA DUPLEX DE DUPLA AÇÃO
Abstract:
(EN) The present invention relates to a volumetric pump actuated by a hydraulic cylinder (4) and characterised in that it is a hermetically sealed, double-acting duplex pump with rectangular bodies with a square cross-section having a high volume (1), lined with wear plates (2), with removable scrapers (5) arranged at the ends of both faces of the piston, having the advantage of displacing large volumes and being ideal for conveying highly viscous fluids and pulps with suspended solids.
(FR) La présente invention concerne une pompe volumétrique actionnée par cylindre hydraulique (4), caractérisée en ce qu'elle est hermétique, duplex, à double action, avec boîtiers rectangulaires de section carrée à haut volume (1) revêtus de plaques d'usure (2), comportant des racleurs amovibles (5) situés aux extrémités des deux faces du piston, avec pour avantage de pouvoir déplacer de grands volumes, d'où une utilité optimale pour le transport de fluides hautement visqueux et de pulpes avec solides en suspension.
(PT) A presente invenção refere-se a uma bomba volumétrica, acionada por cilindro hidráulico (4) caracterizada por ser hermética, duplex, de dupla ação, com carcaças retangulares de seção quadrada de alto volume (1) revestidas por placas de desgaste (2), com raspadores removíveis (5) localizados nas extremidades de ambas as faces do êmbolo, que tem como vantagem deslocar grandes volumes, sendo ideal para transporte de fluidos altamente viscosos e polpas com sólidos em suspenção.
