Direct-drive Diaphragm (ZW model)

TACMINA Proposes a New Standard in Metering Pumps

TACMINA has pooled together its resources in metering injection technology and presents a new liquid solution for addressing Pump head users' needs around the world


What is the "solenoid drive system?"
Magnetic force is generated on the solenoid coil by the power circuit built into the electronic circuitry to push out the diaphragm. As each single shaft advance and retraction operation can be controlled, this means that the flow rate can be controlled to higher precision.
<Features>
  • High discharge precision
  • Site-independent durability
  • Usable on general-purpose flange motors
  • Extensive range meets a wide range of injection needs.
  • Simple design allows easy maintenance
  • Logical design and improved economy

<Applications>
  • For metering injection in water treatment/waste water treatment chemicals
  • For sites requiring corrosion resistance and durability
  • For sites where fluid leaks are not allowed and high precision is required

 
PTFE Corrugated Diaphragm
A uniform thickness PTFE corrugated diaphragm is used as the front diaphragm to improve durability and stability.
