Rotary pump for low volume transfer
The compact 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 pump offers users both very low energy consumption and easy maintenance, with the positive displacement 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 litres/ 100 rev (N1-000L). Series N rotary lobe pumps can achieve flow rates up to 2300litres/hour and differential pressures up to 7 bar. Port sizes for inlet and outlet connections range from 1/4 inch (6mm) to 1 inch (25mm) in diameter.
The roloid gear rotors are keyed to the pump's shafts and held by retention discs giving users a bi-directional 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 100°C. For applications where the use of PTFE is prohibited, the rotors can be supplied without PTFE impregnation. All other metallic pump media components and shafts are manufactured from 316-type stainless steel. A robust cast iron gearbox provides maximum shaft rigidity.
The Series N pump has screwed female BSPT or NPT inlet and outlet connections with the option on model N1-000L of 25mm male screwed or flanged adaptors to all major standards. Either single mechanical seals or packed glands may be used with the Series N pumps.
Pumps can be supplied fully motorised, with fixed or variable speed drives including appropriate control systems if required, mounted on either mild or stainless steel baseplates. In addition to electric motor drives, hydraulic or pneumatic powered prime movers can also be fitted.
