PM500 Series

This is a highly accurate volumetric metering pump for discharging minute amounts of liquid. It can be used with a wide range of liquid viscosities, from low-viscosity materials like water to high-viscosity materials like grease.
The liquid-contacting parts are made of stainless steel and fluororesin, so it can be used with a wide variety of liquids.


The PM500 series has a simple structure with only one valve, so it can be easily disassembled for cleaning and seal replacement.
In addition, the motor-driven type is equipped with a stepping motor, so it can operate at low to stable speeds, and each setting can be easily reset by quantifying it.
*Please use the dedicated controller CP50 or CV4 for the PM500 series.

  • The micrometer makes it extremely easy to adjust the discharge amount.
  • The lightweight and compact design makes it easy to incorporate into automatic machines as well as multi-unit installations.
  • It is designed to be inexpensive among our plunger pumps.
