Valveless Ceramic Pumps

Valveless ceramic pumps from Fluid Metering provide a solution for metering high viscosity grease at low pressure for precision lubrication of industrial robot gearboxes. To maximize productivity and eliminate downtime, industrial robots require continual lubrication. The PDS-100 Programmable Dispensing System utilizes a valveless pumping design to accurately deliver gearbox lubricating grease, independent of viscosity. The system accomplishes this at pressures low enough to prevent any seal damage to the gearbox. It is available in both single and dual channel configurations and is easily integrated with industrial process controllers. Dispense and metering rates range from a few microliters per dispense up to 768 ml per minute continuous metering. The valveless, ceramic pumps have only one moving part in contact with the fluid. The sapphire-hard internal components and valveless design of FMI pumps eliminate accuracy drift typical of pumping systems that rely on valves, diaphragms, peristaltic tubing, and pressurized feed lines for fluid delivery.
