Special Pumps – Model FTL

General Description

Model FTL limestone slurry pump is used to remove sulfur. It is a new generation of desulfurization pump covering all desulfurization process. Its flow rate reaches up to 12000m3/h and flow is usually lower than 100m. It can be used as absorbing tower slurry circulating pump or limestone slurry pump, gypsum slurry discharge pump, recovery pump and pit pump etc.

Advantages:

1. High efficiency, long service life, stable operation.
2. Flow parts material applies corrosion-resistant and wear-resistant Ni-Cr metal, having better chloride resistant stress corrosion cracking capability and mechanical strength.
3. High running reliability. Metal pump overcomes the problems that non-metal liner would fall, tear or deform.
4. Small hydraulic friction loss. Pump efficiency is 3% higher than similar non-metal pump.
5. Flow parts have long service life. Metal protection plate has better resistance to shear sliding wear than non-metal materials.

Pump shaft seal:

Shaft seal applies mechanical seal. It can be equipped with flush water or self-flush type.

1. With water flush: Flush water flow is 0.1~1% of pump flow, but not less than 1 m3/h. The pressure of flush water is 1/2 of pump discharge pressure.
2. Self-flush: Flush mechanical seal with pumped liquid. It is a water saving method.

Applications

Model FTL pump is mainly used to transfer corrosive and abrasive liquids with solid particles. It is widely used in the desulfurization and denitration process in environmental protection industries. It can also be used for other corrosive and abrasive slurries.
