The Series N stainless steel rotary lobe pump from SSP Pumps has been specifically designed for low-volume fluid transfer duties within application areas such as laboratories, pilot plants, chemical processing, electroplating and film processing. Small in size with maximum dimensions of 266 x 136 x 115mm and weighing only 10kg, the Series N pump is ideal for installations where space is restricted. The Series N pump offers users both very low energy consumption and easy maintenance. The positive displacement of the Series N pump is provided by non-contacting, contra-rotating roloid gear rotors within a fully swept pump chamber. Two head displacements are offered: 2.05 litre/100 rev (N1-000S) and 3.86 litre/ 100 rev (N1-000L). Series N rotary lobe pumps can achieve flow rates up to 2300 litre/h and differential pressures up to 7bar. Port sizes for inlet and outlet connections range from 6 to 25mm in diameter. The roloid gear rotors are keyed to the pump’s shafts and held by retention discs giving users a bidirectional flow capability without the need for any modifications. The rotors are made from 316-type stainless steel PTFE impregnated for low friction flow, and are suitable for operation at temperatures up to 100C. For applications where the use of PTFE is prohibited, the rotors can be supplied without PTFE impregnation.
