PWO

PWO

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.
