A SEKO Hub Plunger refers to plunger-style metering pumps from SEKO, like the PS1 or PS2 series, used for precise chemical dosing in industrial settings, featuring robust piston/plunger mechanisms for high accuracy even under varying pressures, accessible through SEKO's online platform, "SEKO Hub", for technical specs and support. These pumps handle aggressive chemicals and deliver small, controlled volumes in applications like water treatment, oil & gas, and more. 
Key Aspects:

• SEKO Hub: A digital portal for SEKO customers to find product info, brochures, videos, and contact support.
• Plunger Pump: A type of positive displacement pump where a plunger moves back and forth in a cylinder to suck in and discharge liquid.
• PS1 & PS2 Series: Specific SEKO models known for their motor-driven plunger/piston action with spring return, offering accurate dosing.
• Applications: Chemical injection, water treatment, boiler dosing, industrial processes (mining, oil & gas).
• Features: High pressure capability (e.g., up to 100 bar for PS2-HP), robust build (stainless steel/PVC), electronic or manual stroke control. 

In essence, it's a powerful, precise chemical pump from SEKO, and "Hub" refers to the digital platform to manage information about it.
