    2008-10-8 · Peristaltic pump accuracy rivals piston pump standards. The typical industry standard for fill volume accuracy is ±0.5%. Peristaltic dispensing pumps meet this requirement for fill volumes as small as 0.5 ml. Below that fill volume, accuracy can be as good as ±1%. When peristaltic pumps are integrated into highspeed filling

  • Piston-Based vs Peristaltic Pump-Based CT Injector

    Methods: The maximum achievable flow rate and the steady-state flow rate variance of a piston-based contrast media injector system (Stellant MP, MEDRAD) was compared with peristaltic pump-based injector systems (CT motion, Ulrich Medical; CT Exprès, Bracco). The contrast media iopromide (Ultravist) and iopamidol (Isovue) were used at 2 concentrations each (300 and 370 mg I/mL) and 3 …

    2017-6-26 · Peristaltic pumps are a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained within a flexible hose or tube fitted inside the pump casing. The actual pumping principle, called peristalsis, is based on alternating compression and relaxation of the hose or tube, drawing content in and propelling product away from the pump.

    2020-11-23 · Piston Pump. In a piston pump the piston slides within a tightly fit cylinder. When the piston retracts, the volume expands. Typically, a valve on the inlet opens, allowing fluid to enter into the pump as the volume expands. When the piston reverses, the volume contracts, and a valve on the outlet opens, allowing the fluid to exit the pump.
