Crest ECB Long Coupled Chemical Pump
Crest ECB Long coupled chemical pumps are manufactured from PP, PVDF or PVC for greater resistrance against corrosion from aggresive liquids in the chemical, pharmaceutical, water treatment and associated industries.

All wetted parts are machined from solid blocks of plastic for the ultimate in robust construction, but all pipeline forces are absorbed by a rugged steel shell. The stainless steel shaft (which is completely sleeved from the liquid) is oversized to minimise shaft deflection and increase the life of the mechanical seal. There is a separate shaft sleeve which is mechanically driven so relieving any additional stress imposed on the impeller.
A wide range of mechanical seals can be fitted including an external PTFE bellows type for clean acids, double pressurized seal assemblies for handling crystalline or abrasive solutions and single internal seals for less
demanding duties.
  • Corrosion resistant non metallic
  • Heavy duty rugged construction
  • Flow up to 240m3/hour
