		Peristaltic pumps work by using a flexible tubing inside a raceway, which is alternately compressed by a set of rotating rollers. This flexing action insulates the materials being transferred from the moving parts of the pump. The advantages are important when transferring sterile solutions, abrasives, inks or any other fluid, which would ordinarily contaminate or destroy the internal components of a pump. Because of the action of the Randolph pump, it is an excellent choice for shear sensitive fluids and applications where fluid metering is necessary. Request Quote

		Econ II Pump Low cost Pumps The 300 (Econ II) series are low cost peristaltic pumps, which are ideal for O.E.M. and laboratory applications. Injection molded from polycarbonate resin, these pumpheads are heat, chemical and impact resistant. The resin incorporates a working temperature range of -32F to 392F. Each pump can accommodare either 3/16" ID x 3/8" OD or 1/4" ID x 7/16" OD, and with the quick release cover design, tubing changes are made much faster and cleaner. CILRAN or Silicone tubing are recommended because of their unique physical properties, however, any flexible tubing with a Shore (scale A) durometer between 35--55 can be used. The 300 pump is standard with a 2 lobe impeller yoke assembly, and also offered in a variety assemblies and drive configurations. Request Quote
