Applications 2 Main features Gear pumps of the series SF are particularly suitable for the transport of media that do neither contain solids nor chemically attack the pump materials while ensuring a minimum lubricity. The standard version is delivered with rotation „clockwise“. Simply turn the pump housing by 180° which - even retroactively – allows a changing of the rotational direction. This also changes the direction of the flow. Upon request we supply the pumps with an adjustable pressure relief valve built in the housing for shortterm protection against pressure spikes. In addition to...
