LEWA diaphragm pump heads, available from Petrenee , allow safe and hermetically tight conveying at medium up to high pressures. LEWA diaphragm pump heads are suitable for a variety of metering and conveying tasks. Environmentally damaging, dangerous, sensitive or abrasive fluids are conveyed with zero leakage pumps.
Sandwich diaphragms with a diaphragm monitoring system are the standard design of all LEWA diaphragm pump heads. Damage of the diaphragm is indicated. The pump still remains tight and operation can be continued for a limited period of time. LEWA diaphragm pump heads are protected against overload by an integrated pressure limiting valve. Following are the advantages of LEWA diaphragm pump heads:
- Economical
- Hermetically tight, zero leakage
- Durable sandwich diaphragm with diaphragm monitoring system
- Protected against overload by adjustable pressure limiting valve
- Minimum maintenance costs as a result of low-wear components
- Safe dry operation
- High metering accuracy by pressure stiff, linear pump characteristics and hydraulic degassing
- Separation of hydraulic and drive element oils
- Gentle conveying of sensitive fluids
- Online and offline condition monitoring systems for electronic monitoring
