The IDS-2000ARH Industrial Dispense Pump is designed for industrial production and process applications requiring maintenance-free, precision, low-volume fluid control. The unit is CE approved and integrates the company's patented CeramPump® valveless piston pumping principal with precision stepper control. The valveless design has only one moving part - a single, rotating and reciprocating piston made of dimensionally stable, chemically resistant ceramics. This design accomplishes all fluid control functions while eliminating valves. Call 800/223.3388.
