14 Intended use 4 Intended use Supplementary information to the 'Intended Use' in the "Operating Instructions for Sigma": The pump is only intended for use in sealed systems with CIP (cleaning in place) in the hygienic sector. (EHEDG-certified, type EL Class I) 14

15 Assembly of the Hygienic Pump Head 5 Assembly of the Hygienic Pump Head Select the hygienic pump head by its identity code under "Dosing head design" - "H hygienic pump head" (only with stainless steel pump heads). The hygienic head is supplied assembled on the pump (welded assembly (item 100)); the valves (item 104) are packed in bags. Assemble the pump so that the EHEDG symbol on the hygienic pump head is legible. Fit the valves (item 104) as shown on the Figure Make sure that the flat inner side of the valves is always facing downwards as well as the O-ring on the fastening body (item 122) - see Figure 61_05-104_01_46-04x01_B2 15

16 Notes on Cleaning Metering Pumps with Hygienic Pump Head 6 Notes on Cleaning Metering Pumps with Hygienic Pump Head General Metering pumps of the Sigma product range, fitted with hygienic head, are used to pump and meter high-grade, hygienically flawless and microbiologically sensitive liquids. They therefore need to be thoroughly cleaned at the end of a production process and be absolutely clean and free of germs that could be harmful to the product, or even pathogens, at the start of a new production process. ProMinent therefore recommends including the metering pumps in an HACCP and/or in-house hygiene scheme. Certification The cleaning-friendly construction of ProMinent metering pumps with hygienic pump head in compliance with the requirements of the EHEDG ( has been confirmed by the TU Munich-Weihenstephan Certification Office and correspondingly certified (EHEDG Type EL class I). Inclusion in CIP (Cleaning In Place) ProMinent recommends including metering pumps with hygienic pump head in the CIP (Cleaning in Place) process. This means that the pump is cleaned in a circular and/or continuous process without having to be dismantled. It involves the following steps, depending on the level of impurities: 1 - Pre-flushing with water 2 - Flushing with alkali 3 - Interim flushing with water 4 - Flushing with acid 5 - Flushing with clear water Flush the liquid end Use a suitable medium to flush the liquid end. 1 Rinsing water 2 Flushing assembly 1 2 P_MAZ_0019_SW Fig. 4: Manual flushing equipment P_MAZ_0020_SW Fig. 5: Automatic flushing equipment There are two versions of flushing equipment: Manual flushing equipment Automatic flushing equipment There are two flushing principles: Flushing when metering is interrupted (intermittent flushing) Flushing when metering is finished. Problems may arise if flushing cannot be performed properly. Ensure that the metering pump is idle during flushing. Do not exceed the maximum permitted flushing pressure of 2 bar! 16

17 Notes on Cleaning Metering Pumps with Hygienic Pump Head Flow velocity Fundamental prerequisite for a successful CIP (cleaning in place) is a turbulent flow at a minimum flow velocity of 1.5 m/s based on the pipe diameter of the pump inlet. Should this flow velocity not be reached due to the inherent capacity of the pump type, then a centrifugal pump should be installed upstream as a booster pump. However, never exceed the maximum permitted priming pressure on the suction side - see "Technical Data". Stroke rate and stroke length The metering pump should run at a minimum stroke rate of 72 strokes/min and at 100% stroke length during CIP (Cleaning in Place) to ensure that liquid flows perfectly through the hygienic pump head. Drainage of residual liquid / Self-draining Tightly sealed non-return valves are fitted in ProMinent metering pumps with hygienic pump head. That is why the dosing head needs to be manually drained after the CIP (Cleaning in Place) step by opening the clamps and/or using compressed air to ensure that any residual liquid is drained. In doing so it is imperative that you ensure using fittings and pipework that no cleaning solution can enter parts of the system that carry product. When using compressed air, use appropriate fittings and pipework to ensure that any residual liquid is fully blown out. Make sure that the pump is at a standstill when doing so. Materials of wetted parts The following wetted materials are used in ProMinent metering pumps with hygienic pump head: A A 61_05_104_01_47 Fig. 6 Item. no. Wetted materials 100 Stainless steel , 122, 123 Stainless steel PTFE 125 Gylon BIO PRO (PTFE material) Part of 122 EPDM, if item 122 has a seal Gylon BIO PRO is a registered trademark of Garlock Sealing Technologies 17

18 Notes on Cleaning Metering Pumps with Hygienic Pump Head Chemical resistance Check the resistance of the wetted parts to the CIP (Cleaning in Place) media used in detail. Temperature resistance ProMinent metering pumps with hygienic pump head can be exposed to temperatures of max. 120 C at 2 bar for a maximum of 15 minutes. Process connections ProMinent metering pumps with hygienic pump head are supplied as standard with welded ends in compliance with DIN Range 2. The pumps are dismantled by loosening the BIO CONNECT clamp connection by means of which the valves can be separated into a top and bottom half. Note this when designing the connecting pipework. Connection adapters can be customised and fitted at any time. Cleaning without CIP (Cleaning in place) Adapt the cleaning process if no CIP-compatible connections (e.g. milk pipe connectors DIN 11851, hose connectors, Clamp DIN 32676) are used or only used to a limited extent. 18

19 Inspection / Troubleshooting 7 Inspection / Troubleshooting Regularly check and, if necessary, replace the "Hygienic valve seal TCVC" (121). Replace the "Hygienic valve inner part EPDM with seal" (122) if it is damaged or worn. Replace the "Hygienic valve inner part EPDM with seal" (122) if the pump leaks at the valve. 19
