Caustic and alkaline liquids

Sodium hydroxide filling machines for caustic chemical products.

Sodium hydroxide and caustic soda products can be aggressive to unsuitable seals, hoses and pumps. Filling machinery should be specified around concentration, viscosity, temperature, pack format and operator protection.

What to check

Build the specification around the liquid and pack.

Sodium hydroxide and caustic soda products can be aggressive to unsuitable seals, hoses and pumps. Filling machinery should be specified around concentration, viscosity, temperature, pack format and operator protection.

Before a machine is shortlisted, the product data, fill volume, container shape, cap or closure, batch size and target output should be reviewed together. This helps avoid choosing equipment that fills the liquid but struggles with the finished pack.

Important quotation points

  • Review concentration, temperature and compatibility with all wetted parts.
  • Consider splash control and drip collection around the filling heads.
  • Check whether bottles, jerrycans, pails or drums need separate handling.
  • Review cap type, torque and line cleaning procedures.

FAQ

Sodium Hydroxide Filling Machines UK questions

Can caustic liquids use standard pumps?

Only after compatibility review. The formulation and concentration determine what materials are suitable.

Can viscous caustic products be filled?

Yes, but the pump and nozzle choice should match viscosity, fill volume and drip behaviour.

Can a line fill both caustic and detergent products?

Possibly, but cleaning, compatibility and changeover controls need to be reviewed.
