Pump for hygienic applications Sigma Hygienic

for food productswith electric motordiaphragm

Hygienic design: Precise and hygienic metering The hygienic design version of the Sigma diaphragm metering pump is optimised in terms of dead space, features as few gaps as possible and has smooth, wetted surfaces for flexible and easy use in hygienically sensitive applications. The simple construction and smooth surface make easy CIP possible and allow the device to be dismantled at speed. Ball non-return valves and EPDM seals ensure gentle and reliable metering for tasks with strict hygiene requirements (when working with aqueous foods or food additives). Features: CIP-capable up to 130 °C, max. 2 bar, max. 15 min. Smooth surfaces: electropolished Ra ≤ 0.8 µm (wetted), optimised in terms of dead space and liquid end with as few gaps as possible Integrated controller, universal and flexible: External activation via potential-free contacts, mA or ProfiBus and/or ProfiNet via Dulconvert Remote transmission of operating statuses via an additional output or relay module Wide-range voltage power unit, power supply: 1 ph, 100 – 230 V ±10 %, 240 V ±6 %, 50/60 Hz Stroke length adjustment range 0 – 100% IP 65 degree of protection Confirmations: FDA, 1935/2004, AoF, BSE/TSE EN10204 Type 2.2 factory certificate for surface roughness Ra ≤ 0.8 µm GMP EC 2023/2006 Wide range of different drive units, also for use in hazardous areas (ATEX), and different flange versions (Sigma Basic) EN 10204 3.1 material certificate, performance curves (on request)
