Motor-Driven Metering Pump Sigma Hygienic

Capacity range of the Sigma: 25 – 1,000 l/h, 10 – 4 bar

The hygienic design version of the sigma diaphragm metering pumps 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.

Hygienic Design: Meter Precisely and Hygienically

The hygienic design version of the sigma diaphragm metering pumps 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).

The DGUV test certificate for “Sigma metering pumps in the hygienic design” with its extensive testing provides additional peace of mind – a huge benefit for ProMinent customers.

Like all intelligent ProMinent metering pumps, the sigma product range can be flexibly controlled using a highly diverse range of signals. Designed for continuous operation, hermetically sealed and without a shaft passage into the metering chamber, providing simple and reliable handling. The PTFE multi-layer diaphragm with diaphragm rupture control as standard offers additional process reliability.

Your benefits

  • Process reliability thanks to PTFE multi-layer safety diaphragm with condition monitoring
  • Fast CIP, reliable operation and easy handling
  • Simple construction, optimised in terms of dead space and small number of parts, reliable operation, no shaft passage into the media chamber
  • Precise metering thanks to the option for adjusting the metering volume in 1% steps by means of stroke rate and stroke length
  • Physiologically safe wetted materials (FDA and 1935/2004); reliable and flexible Sigma motor-driven metering pump with ball non-return valves enables a wide range of applications
  • Flexibly connectible: connection to process control systems via integrated PROFIBUS®, CANopen interface
