ET – Ceramic Lined Double Mechanical Seal Chemical
Process Pump

Back to Product Guide

  • Pump dimensions to DIN EN ISO 2858
  • Metal casing with a thick abrasion-, corrosion- and permeation-resistant ceramic lining
  • Ceramic lining ensuring outstanding chemical resistance
  • Non-clog, wear-resistant open impeller allowing easy and accurate clearance adjustment and delivering low NPSH
  • FuturaMik® double mechanical seal excellently suited to abrasive fluids with a high solids content and tending to crystallise and/or polymerise; no metal parts on the product side
  • External arrangement preventing the mechanical seal parts from clogging or sticking
  • Other standard commercial mechanical seals available
  • Pump designed as a modular system constructed with robust components
