In addition, a thermal stator protector (STP-2 or STP-D) for overheating and dry running protection is available. 3 Housing/discharge flange The pump housing has a reduced diameter for optimal flow velocity and minimized pump volume. The body flange is located directly above the shaft seal avoiding any dead space. Therefore the deposit of fluid in the housing during the manufacturing cycle is eliminated. 4 Flexible rod 5 Double buffered static seals All static seals to the atmosphere are double sealed chambers. Sterile condensate, vapour and/or detector fluid is continuously supplied to the chambers. Through the contaminationproof design the process cycle can be reduced by the removal of some steril- ization processes. Consequently output capacity increases as the number of cleaning cycles decreases. 6 Sealing housing Double machanical seal in tandem arrangement with unpressurized, static or dynamic quench. 7 Bearing housing Widely spaced, heavy duty bearings ensure optimum concen- tricity of the drive shaft and are able to withstand large axial loads. The free shaft end allows for the use of all types of drive. 11 Characteristics and typical components Flexible rod The flexible rod for universal use in the NEMO® Hygienic Plus series is corrosion-proof, with no dead space, wear and maintenance free because there are no components moving against each other as in other joint types. Neither lubri- cation nor seals are required so that the lubricity of the fluid does not have to be taken into consider- ation. Ideal for pumping highly sensitive products with or without solids and for uncompromising hygienic applications. Also available as a 3-A flexible rod.Double mechanical seal in tandem arrangement Double mechanical seal in tandem arrangement with unpressurized, static or dynamic quench. Mechanical seals in SIC. Elastomer in compliance with FDA standards. The design of the rotating unit guarantees the seal integrity at changing temperatures and pressures. The seal complies with EHEDG and QHD regulations. Pipework (optional) The pipework circulates sterile condensate, vapour and/or detector fluid to the double acting, closed seal lines. CIP/SIP Process For the CIP process, the entire system requires a cleaning fluid velocity of at least 1.5 m/s and to facilitate this the NEMO® hygienic and aseptic progressing cavity pumps are equipped with additional cleaning ports. The position of these ports can be determined to suit the appli- cation, they require a bypass pipe. The bypass is also required for the SIP process. In both the CIP and SIP processes the NEMO® pumps are operated intermittently. Tangential cleaning ports guarantee complete emptying of the NEMO® pump. All pump materials used are suitable for CIP and SIP processes. NPS · 308 · 02 · 03/18 · 04 · Technical specifications are subject to change.
