Valveless Ceramic Pumps provide a solution for metering high viscosity grease at low pressure for precision lubrication of industrial robot gearboxes. The PDS-100 Programmable Dispensing System uses Company's valveless pumping design to accurately deliver gearbox lubricating grease, independent of viscosity. The unit accomplishes this at pressures low enough to prevent any seal damage to the gearbox. The device 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. These pumps have only one moving part in contact with the fluid. The sapphire-hard internal components and valveless design eliminate accuracy drift typical of systems that rely on valves, diaphragms, peristaltic tubing and pressurized feed lines for fluid delivery.
