Parker's micro diaphragm pump is ideal for higher performance fixed and portable air and gas applications requiring high flow(up to 2.5 slpm), pressure, and vacuum, high efficiency, long life, small size, light weight, and intrinsic safety capabilities.

Product Information

T2-03 DC motor-driven diaphragm pump series is a 16mm wide miniature diaphragm pump ideal for use in fixed and portable air and gas applications with stringent gas tightness requirements. The pump head and patented valve design provide reliable, highly efficient, long life operation with optimized size and power draw. Three motor options are available (Iron core, Coreless, Coreless Premium Duty) to meet a variety of application requirements, including intrinsic safety capability.
  • Parker's T2-03 pumps are ideal for customers looking for a high performance, highly efficient and intrinsic safe capable micro air/gas pump in tight spaces within today's handheld industrial devices and small medical instruments.
  • Provide up to 2.5 LPM and 530 mmHg in a 85g package providing the highest flow rates available with lowest power consumption for extended battery life.
  • Our micro diaphragm pump technology is highly configurable with options for low power  and high efficiency.
