Product Overview

The TBTL series is core equipment purpose-designed for wet flue gas desulphurisation (FGD) systems, used primarily for pumping recirculating slurry in the absorber tower. The series offers a wide capacity range, high efficiency and energy savings, a compact footprint, stable operation and easy maintenance.

Key Technical Features

High efficiency

Energy saving: Wetted parts are optimised using ANSYS fluid simulation for excellent hydraulic performance and higher pump efficiency.

Duty adaptability

An adjustable bearing assembly precisely trims the impeller’s axial position, keeping the pump efficient over the long term and saving energy.

Simple servicing

Back pull-out design allows maintenance without disconnecting suction or discharge piping, cutting downtime.

Durable bearings

Double-row tapered roller bearings at the pump end and cylindrical roller bearings at the drive end, oil-lubricated for high load capacity and long service life.

Purpose-built FGD seal

Cartridge mechanical seal with low leakage and simple alignment during installation.

Compact footprint

An X-type compact bearing frame saves space — ideal for the confined areas typical of FGD islands.

Wear- and Corrosion-Resistant Material Options

For the severe corrosion and high abrasion of FGD slurries, we have developed a dedicated new wear- and corrosion-resistant alloy that combines the corrosion resistance of duplex stainless steel with the wear resistance of high-chrome cast iron, delivering outstanding performance.

Configuration Options

Sealing Method:

Mechanical seal: The dedicated sealing package comes as standard with a cartridge mechanical seal designed for FGD duty — reliable operation, low leakage and simple alignment.
