Aseptic solutions for metering sensitive fluids
LEWA hygienic metering pumps are hermetically sealed, leak-free, and have no connection to the product chamber. This ensures contamination-free metering and conveying.
Advantages of hygienic metering pumps:
- Liquid end hermetically tight, 4-layer safety diaphragm with leakage detection
- Superior priming, low shear and wear
- CIP/SIP up to 150°C
- Aseptic design according to EHEDG
- Compact servomotor without fan (cleanroom)
- 316L or higher (e.g. hastelloy) and plastic
- Continuous operation possible
- ATEX design possible
- Qualified in the OEM pharmaceutical sector worldwide for decades

Background
Background information for sterile applications
GMP stands for "Good Manufacturing Practice" for Medicines. For example, the GMP rules lay down requirements for hygiene, premises, equipment, documentation and controls.
The production of sterile products, such as pharmaceuticals, therefore has special requirements in order to minimize the risk of contamination with microorganisms, particles and pyrogens. Quality assurance is of particular importance in this context. Production must be carried out strictly according to defined and validated methods and procedures.
The metering pumps used are an important component of the production facilities. Therefore, they must also meet the GMP requirements. Important properties include CIP/SIP cleanability or hermetic tightness.
