Iwaki America SP Series Bellows Metering Pumps
Bellows Metering Pumps are an inexpensive solution to low-pressure metering applications. The simple design involves a flexible polypropylene bellows and a pair of EPDM or Viton check valves. These pumps deliver repeatable flow in a range between 11 to 2100 ml/min, and are limited to 5-10 psi depending on the exact model. These are used most often in OEM photoprocessing equipment, but can be an ideal pump for any low-pressure metering requirement.
