The ZFT Series uses magnetic force to transmit torque from the motor to the internal rotating assembly. The external magnet rotates with the motor, while the internal magnet drives the impeller through a sealed isolation sleeve.
Because no rotating shaft passes through the pump casing, the design removes the conventional dynamic shaft seal. This reduces leakage points associated with seal wear and makes the pump suitable for handling corrosive, volatile and hazardous liquids.
The integrated self-priming chamber retains liquid after initial priming and allows the pump to draw liquid from a source below the pump inlet.
The magnetic coupling eliminates the conventional dynamic shaft seal between the motor and the pumped liquid.
Benefits:
Reduces external leakage risk
Prevents dripping caused by mechanical-seal wear
Supports enclosed chemical transfer
Reduces mechanical-seal maintenance
Protects valuable and hazardous liquids from external contamination
The ZFT self-priming chamber supports suction from low-level tanks and chemical containers.
Benefits:
Suitable for tank-truck unloading
Supports low-level storage-tank transfer
Reduces dependence on permanently flooded suction
Simplifies intermittent chemical transfer operations
Provides self-priming heights up to 3 m
The pump casing combines a steel supporting structure with an F46 fluoropolymer lining. The steel structure provides mechanical strength, while the F46 lining isolates the pumped liquid from the metal casing.
F46 is an FEP-type fluoropolymer used in corrosive fluid-handling applications. FEP materials provide strong chemical resistance, low moisture absorption and high resistance to weathering.
The non-metallic isolation sleeve separates the internal and external magnetic assemblies. It reduces eddy-current losses associated with metallic isolation sleeves and supports efficient magnetic torque transmission.
The motor and pump are connected through a compact intermediate support structure.
Benefits:
Compact installation footprint
Simple equipment layout
Reduced alignment requirements
Convenient disassembly
Easier routine maintenance

Industrial wastewater treatment
Chemical batch transfer
Volatile liquid transfer
Hazardous liquid transfer
High-value process liquid transfer
Chemical production lines
Environmental protection equipment
The ZFT fluoroplastic magnetic pump is designed for transferring corrosive industrial liquids compatible with its F46-lined wetted construction.
Typical liquid types include:
Sulfuric acid solutions
Hydrochloric acid solutions
Nitric acid solutions
Phosphoric acid solutions
Sodium hydroxide solutions
Acidic wastewater
Alkaline wastewater
Chemical salt solutions
Electroplating liquids
Corrosive process water
Compatible organic solvents
Volatile chemical liquids
The pump is intended for liquids without high concentrations of abrasive or ferromagnetic particles.
The 32ZFT-25F and 40ZFT Series provide flow rates from 3.6 to 6 m³/h. These models are suitable for smaller chemical transfer systems, process equipment and intermittent unloading duties.
The 50ZFT Series provides a rated flow of 12.5 m³/h with 20, 30 and 45 m head options. These models support medium-capacity chemical transfer and circulation systems.
The 65ZFT Series provides flow rates from 12.5 to 25 m³/h with head options from 20 to 45 m. These models are suitable for chemical production lines and larger unloading systems.
The 80ZFT Series provides published flow rates up to 60 m³/h and motor powers up to 18.5 kW. These models support large-volume corrosive liquid transfer systems.
The ZFT model designation identifies the connection size, pump series, nominal performance designation and fluoroplastic-lined construction.
Example:
65ZFT-30F
65: inlet-size designation
ZFT: self-priming fluoroplastic magnetic pump series
30: nominal head designation
F: fluoroplastic-lined construction
Comparison | ZFT Self-Priming Magnetic Pump | Standard Magnetic Pump |
|---|---|---|
Self-Priming | Yes | Normally requires flooded suction |
Dynamic Shaft Seal | None | None |
Low-Level Tank Suction | Suitable | Limited |
Tank-Truck Unloading | Suitable | Requires an appropriate inlet arrangement |
Chemical Circulation | Suitable | Suitable |
Magnetic Transmission | Yes | Yes |
Fluoroplastic Construction | Yes | Available according to model |
Main Advantage | Self-priming plus seal-less transfer | Simple seal-less continuous transfer |
The ZFT Series is more suitable for suction and unloading duties, while standard magnetic pumps are commonly used in flooded-suction circulation systems.
