TZB Fluorine-Lined Self-Priming Pump for Acid and Alkali Transfer
The TZB fluorine-lined self-priming pump uses reinforced PTFE, FEP or PFA wetted parts for strong acids and alkalis, with a typical self-priming height of 1-3 m and selected models up to 4 m.
TZB Fluorine-Lined Self-Priming Pump for Acid and Alkali Transfer
Convenient suction lift for corrosive acid and alkali transfer
The TZB fluorine-lined self-priming pump combines self-priming capability with fluoroplastic corrosion resistance. The impeller, pump cover and other wetted components use fluoroplastic materials such as PTFE, FEP or PFA and are formed by an integral sintering process. Metal inserts reinforce the structure, allowing the liquid-contacting surfaces to resist aggressive chemicals while the internal support carries industrial operating loads.

Self-Priming Function
A self-priming pump can evacuate air from the suction line after the casing has been correctly filled and prepared, making the design useful where the liquid source is below the pump or where frequent transfer between containers is required. The typical self-priming height of the TZB fluorine-lined self-priming pump is 1 to 3 m, and selected models can reach 4 m under suitable conditions. Actual lift depends on liquid density, vapor pressure, temperature, suction-pipe length, airtightness and installation elevation.
Chemical Resistance
The fluoroplastic wetted components are suitable for many strong acids, strong alkalis and organic solvents. Typical media include sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, sodium-hydroxide solutions, methanol, acetone and aqua regia. Final compatibility must include every wetted material and should be confirmed from the chemical concentration, temperature and impurities before the TZB fluorine-lined self-priming pump is ordered.
Operating Range
The published TZB series covers flow rates from 1 to 1600 m³/h and heads from 5 to 125 m. Available configurations are intended for temperatures from -20 to 80°C. These are series limits; each model has an individual hydraulic curve and self-priming performance. The selected pump should operate close to its recommended range for stable capacity, energy use and service life.
Applications
The TZB fluorine-lined self-priming pump is suitable for chemical plants, electroplating lines, pharmaceutical production, fine chemicals, petrochemical facilities, metallurgy, industrial wastewater treatment and mobile or intermittent liquid-transfer systems. Common uses include unloading tanks, draining sumps, transferring acid between containers, feeding treatment equipment and recovering corrosive liquids from below-floor-level collection points.
Suction-Line Requirements
Self-priming performance depends heavily on the suction system. Use a short, airtight suction pipe with the correct diameter and as few bends as practical. Avoid high points that trap air. Every flange, threaded connection and valve on the suction side must be sealed. The actual vertical lift should include friction loss, and hot liquids may require a lower lift because available suction pressure decreases as vapor pressure rises.
Data Required For Correct Selection
Provide normal and maximum flow, total head, vertical suction lift, horizontal suction length and pipe diameter. Also provide the liquid name, concentration, temperature, density, viscosity, vapor tendency and any solids content. Specify the motor voltage, frequency, installation environment and operating schedule. These details allow the TZB fluorine-lined self-priming pump to be selected for the real system.
Start-Up Procedure
Before the first start, fill the pump casing according to the operating instructions and confirm that the suction line is complete and airtight. Verify motor rotation and the correct valve positions. Do not run the pump dry while waiting for liquid to arrive. If priming takes longer than expected, stop the unit and check the fill level, suction joints, lift, rotation and blockage rather than allowing continued dry operation.
Shutdown And Maintenance
If the medium can crystallize, solidify or leave deposits, flush the wetted passage after shutdown with a compatible liquid. Inspect for changes in priming time, discharge pressure, noise and vibration. Longer priming time can indicate air leakage, internal wear or a blocked return passage. Maintenance intervals should reflect the operating hours and chemical severity.
