Rotary lobe pump EP series

oilelectricself-priming

The rotary lobe pump is a positive displacement pump. The pumping principle is based on two counter-rotating pumping elements, known as the rotary lobes. These are mounted on two synchronized shafts. The rotational movement of the lobes increases the volume of the pumping chamber on the suction side. This creates suction, which draws the medium into the rotary lobe pump. As the rotational movement continues, the medium is then enclosed in cavities between the rotary lobes and pump housing and it is issued on the discharge side by the pumping chambers as they reduce in size again; the rotary lobe pump conveys the medium directly. Due to their mirror-symmetrical design, rotary lobe pumps are independent of the direction of rotation and can pump in either direction without restriction. The HiFlo lobes developed in the 1990s operate pulsation-free, ensuring low-vibration and exceptionally gentle pumping. Demanding applications with abrasive, chemically aggressive and hot media? The EP series has been developed precisely for these applications, e.g. in the oil and gas industry, in the production of sugar, paints and varnishes and in tank farms. The high-performance gearbox with helical gears generates pressures of up to 18 bar with incomparably quiet running. The low-pulsation pumping reduces wear on the adjacent piping to a minimum. For high operational reliability, the pump is equipped with an AirGap. This gap provides atmospheric separation between the gearbox and the pump chamber. Even in the event of a leak, no liquid enters the gearbox, but flows off to the outside.
