Metering pumps for high-pressure, low-viscosity fluids
As part of this company’s Pulseless Flow range of high-precision gear-metering pumps, the SPLV model (photo) has been designed to pump low-viscosity fluids, including acids, solvents, resins and water, even under high pressure while maintaining constant levels of speed and accuracy throughout the process. Pulseless Flow pumps are built around hardened steel involute gears that are machined to precise tolerances of one or two microns. This results in extremely small, controlled clearances between the gear and mating components, ensuring almost no internal slip even at high pressures. This level of precision means the pump is able to control and meter the flow with extreme accuracy and repeatability under differential pressures of up to 50 bars. The pumps are built with gears engineered entirely from martensitic stainless or cobalt-chromium steels for optimum strength and dimensional stability. According to the manufacturer, these are the only precision pumps in the market built specifically to address the characteristics of low-viscosity fluids in high-pressure applications.
