Description<\/h4>\n
\n
Bare shaft gear pump,\u00a0<\/b>mounted on a baseplate with a electric motor attached with an elastic coupling.<\/li>\n
The helical gears<\/span><\/a> allow a smoother and quieter operation of the pump.<\/li>\n
It is a self-priming pump.<\/strong> That is to say, with the installation empty, the pump is able to aspirate the liquid causing a vacuum pressure in the suction pipe.<\/li>\n
The design integrates a safety valve<\/strong> in the gear casing that is capable of relieving the pressure in case the working limits are exceeded.<\/li>\n
Suitable for transferring fuel oils, lubricants, animal or vegetable fats and others.<\/li>\n
The series is available in EL-Bare shaft<\/strong> without motor (R-EL) or SB-On basepalte<\/strong> with an electic motor attached with an elastic coupling (R-EL SB)<\/li>\n
Sealing solution by means of a mechanical seal or lip seals depending on the model, in accordance with the application.<\/li>\n
The SB-On baseplte\u00a0<\/strong>version with motor includes a bare shaft gear pump mounted on a sturdy metal sheet baseplate with its motor attached by means of a properly protected felxible coupling.<\/li>\n
Lastly, the R-EL (SB) series can be installed\u00a0in explosive atmospheres in accordance with ATEX<\/strong> directives.<\/li>\n<\/ul>\n
\n
For monoblock versions, see the R<\/span><\/a> and R-U<\/span><\/a> series.<\/span><\/h3>\n
