Standard model basic type, inverter built-in control type.

【Basic Type】 A standard model driven by a general-purpose motor. It can be modified to standard, low-cost, explosion-proof, inverter motor-driven types, etc. (It does not have the various functions of the Sigma Control type.) It can accommodate specifications not only for Japan but also for overseas (IEC standards, NEMA standards). 【Control Type】 The control type is a diaphragm-type metering pump with a built-in inverter motor drive. It allows for discharge settings in units of one stroke linked to external inputs, enabling handling similar to that of an electromagnetic drive pump. Additionally, it features a new function with a three-stage stroke speed switching capability, accommodating a wide range of chemical injection environments.
