Description for Seim PWO Series 3 Screw Pumps

Used with low-viscosity fluids such as LSMGO and light gas oils with standard viscosities between 1.2 cSt and 10/15 cSt, typically used with Boiler systems with pressures up to 40 bar and flow rates of 560l/min (33.6m3/h). Its high self-priming strength and its capacity to operate at low viscosities make it very a suitable pump for applications with fluids that do not include lubricating properties among its main characteristics.Design available SEIM standard. mechanical or radial seal - incl. versions with high wear resitant liner (models PWA and PWE) Flow Rate USGPM 172 Suction pressure Mechanical seal: from -0,5 to 10 bar (-8 to 145 psi) - Radial seal: 0 to 1,5 Bar (0 to 22 psi) * Seal Radial or mechanical Bearing Radial ball Bearing lubrication Self-lubricated external Safety valve Available BVPA model as built-on, for sizes 025 to 045 * OPERATING CONDITIONS Fluids: Water based emulsion (min. 5% oil content) - Cutting oils - Light fuel oils.
