Introduction
ㆍ Did you ever see pulseless metering pump?
In general, Metering pumps have advantages for high discharge pressure, fixed quantity, and corrosion resistance, but it could be restricted for use according to the process because it have characteristic arising pulsation in injection side caused by operating principle.
Cheonsei has developed constant velocity cam which removes its characteristic radically, and has completed Smoothy Metering Pumps as patent technology for correction of constant velocity cam.
It has acquired Certificate of New Excellent Product(NEP) and Excellent Performance Certification(EPC) by patent technology.
