Solution
LEWA process diaphragm pumps convey caprolactam melts controllably via a frequency converter.
Performance example:
- Temperature: 100°C
- Flow rate: 11m3/h
- Pressure: 36 bar
LEWA triplex process diaphragm pumps offer the following advantages:
- Outstanding service life in comparison to conventional screw pumps, for example
- High efficiency
- Safe and gentle operation with caprolactam melts
- Proven and complete system solution
- Low investment and operating costs
Background
Caprolactam is the starting material for the ring-opening polymerization of polyamide 6 (perlon).
A second option for polymerization is in the hydrolytic splitting of the amide bond and subsequent polycondensation. Polyamide 6 is produced yearly by the megaton.
At ambient temperature, caprolactam forms white crystals, which are quite soluble in water. Therefore it is normally stored at temperatures over 80 °C until it is used.

With its varied properties, it is an ideal initial material for a wide variety of products:
- Engineering plastics, such as tool parts and molding parts
- Carpets and household textiles
- Packaging film
- Stockings, bathing suits and special suits
- Fishing nets, brushes, wires and cables
