Thermoplastic Acid Pumps

MAXWOR thermoplastic acid pumps are centrifugal pump systems with plastic housings designed for the safe transfer of highly corrosive chemicals, acids, and aggressive fluids.

In chemical environments where metal-bodied pumps cannot withstand exposure, thermoplastic materials provide high chemical resistance and long service life.

Developed for chemical, surface treatment, coating, and wastewater treatment plants, these pumps offer easy maintenance, leak-free operation, and safe chemical transfer advantages.

Technical Specifications

Operating Principle

Thermoplastic acid pumps operate based on the centrifugal principle.

The impeller, connected to the motor shaft, imparts kinetic energy to the fluid, and this energy is converted into pressure energy inside the pump casing, enabling the liquid to be delivered to the discharge line.

In magnetic drive models:

  • there is no shaft seal
  • sealing is provided by magnetic torque
  • leakage risk is reduced to a minimum

This structure provides significant safety advantages, especially for the transfer of hazardous, aggressive, and volatile chemicals.

Design & Material

Thermoplastic acid pumps are designed with different thermoplastic and technical material options depending on the temperature, concentration, and aggressiveness of the chemical to be transferred.

Casing Options

  • PP (Polypropylene)
  • PVDF
  • PE (Polyethylene)
  • PTFE coated versions

Impeller

  • PP
  • PVDF
  • ETFE coated

Shaft & Internal Parts

  • Ceramic shaft

In pump selection;

  • chemical type,
  • concentration,
  • temperature,
  • flow rate and head requirement,
  • continuous operating time,
  • preference of magnetic drive or mechanical seal

must be taken into consideration. Incorrect material selection may lead to cracking, deformation, or chemical reaction risks.
