Corrosive chemical transfer — safe, leak-free
Pumps for transferring acid, solvents, corrosive chemicals between storage tanks, drums, IBCs and production lines — safe loading, unloading and dispensing for each fluid.
ATEX Certified · ISO 9001 · FDA Compliant · Zero-Leak — TKT selects the model by each fluid, each transfer route and wetted materials.
Which routes does the chemical travel?
Chemical transfer pumps are a specialized group of pump equipment used to move, transfer or load/unload corrosive chemicals — acid, alkaline, solvents, slurry — between storage tanks, drums, IBC tanks and production line pipework. Unlike standard water pumps, these require wetted materials (pump body, diaphragm, seal, O-ring) compatible with the specific fluid. Selection depends on two main factors: transfer route (fixed tank → continuous piping, or mobile drum/IBC batch transfer) and fluid properties (corrosivity, temperature, viscosity, ATEX/FDA requirements). The four common technologies include: plastic-lined centrifugal (continuous high flow, up to 2,000 m³/h), sealless mag-drive (zero-leak for acid/solvents), air-operated diaphragm pump AODD (mobile drum/IBC, ATEX zone no electricity needed), and drum pump/electric diaphragm pump EODD (when power supply is available).
The route determines the pump. Fixed route, high flow leans toward plastic-lined centrifugal or sealless mag-drive; mobile drum/IBC route leans toward AODD/EODD diaphragm pump or drum pump. Let TKT know the fluid and transfer line to narrow down the right pump category.
How do you need to transfer the fluid?
Select the relevant scenario to view the solution and specific model below.
Corrosive chemical transfer — zero-leak
- Loading/unloading acid, base, plating solution between tank ↔ process line
- Zero-leak requirement
- Continuous transfer, fixed installation on pipeline
- Wetted material PP or PVDF
Continuous transfer tank → process line, high flow rate
- Transferring corrosive chemicals from large tank to process line
- Thermoplastic-lined pump casing (PP/PVDF/PTFE)
- Installed to DIN/EN 22858 · ISO 2858 standard
- High flow rate, continuous, fixed installation
Transfer with electric diaphragm pump — where power is available
- Power available, no compressed air desired
- Batch transfer, drum/IBC suction, self-priming, dry-run capable
- Saves compressed air compared to AODD
- Fluid with light solids, moderate viscosity
Mobile drum / IBC transfer — no electricity
- Solvent and flammable chemical transfer — ATEX required
- No electricity, compressed air only
- Fluid with solids/slurry or dry-run risk
- Mobile drum/IBC transfer, self-priming
Selecting a transfer pump requires full transfer context
Which fluid, from where to where (tank ↔ drum ↔ IBC ↔ process line), flow rate and wetted material — all affect the right model. Every wetted component — pump casing, diaphragm, O-ring, gasket, flexible hose — must be checked for compatibility. TKT requires full specifications before recommending a model.
