Pharmaceutical IndustryRPompe S.P.A.Mechanical seal arrangementThe lined shaft seal chamber with its conical design can accommodate the following mechanical seal types :• CDR FC-35 Single mechanical seal (Lined PFA or PP )• CDR FC-TC35 Double cartridge mechanical seal (Lined PFA)• Single-acting and double-acting mechanical seals configuration, also on cartridge executionUCN-BLClose coupled pumps are furnished with standard motorsUCN-LBare shaft pumps use the back pull-out principle and a strong bearing housing with flexible couplingUCN SERIESwww.cdrpompe.it3D VIEW Rigid shaft made of corrosion resistant stainless steel minimizes the shaft deflection < 0,05 mm : the design is in “dry shaft execution” where there is no contact between shaft and medium.Pumps design grants a modular configuration of either bare shaft end or close-coupled design.All PFA components are made through Transfer Moulding process. The Transfer Moulding process is also employed for PVDF\\\\PP casing and seal chambers.All wetted parts have a high chemical resistance employing a performing material as Virgin unfilled PFA, granting also a wall thickness of at least 4 mm to 5 mm Virgin PFA.Alternative available materials for the wetted parts: PP and PVDF.The suction cover is designed to guarantee a long life time even under stress, in fact it’s a lined armored piece made around a strong metal core.All the UCN pumps can be equipped with closed, open radial or vortex impellers in single flow, single stage execution.Oil sump with enlarged volume ensures cool and clean oil.RPompe S.P.A.FEATURESClosed impellers are indicated to be used with clean liquid. They have a good hydraulic efficiency and there’s no recirculation between the blade’s plane.Semi - open Radial impellers are indicated to be used with high solids concentration liquids. They have a low hydraulic efficiency and there’s recirculation between the blade’s plane.Semi - open Vortex impellers are indicated to be used with very dirty liquids. They have a low hydraulic efficiency and there’s recirculation between the blade’s plane.LINED SEAL CHAMBER• Wide conical design equipped with breaking ribs. • Available in PFA,PVDF or PP lined execution and in a conical shape .• The conical seal chamber is designed to push away from the seal solids and slurry, back into the flow path of the process liquid.• Self-venting, Self-flushing, Self-draining.LINED IMPELLER• The combination of a solid metal core and a Fluopolymers lining (PFA \\\\ PVDF \\\\ PP) made by Transfer Moulding assure an excellent mechanical reliability and an optimal chemical resistance.• The problem of reverse rotation during start-up has been eliminates thanks to the key driven system.• Standard back vanes reduce axial thrust an seal chamber pressures to guarantee and extraordinary bearing and seal life.LINED CASING• The ductile cast iron armour protects the fluoroplastic peripheral surfaces of the pump from pipe strain, vibration, external shocks and during the handling; moreover it allows the casing to be Vacuum resistant.• Top centerline discharge for air handling, self-venting.• Drained casing (optional).www.cdrpompe.itCDR FC-TC- 35 DOUBLE CARTRIDGE SEAL TAPERED SEAL CHAMBER EXTERNAL FLUSHED• Applications where no leakage can be tolerated e.g. hazardous, toxic, inflammable media.• For dirty, abrasive or polymerizing products where media is unsuitable as a lubricant for inboard seal faces.• When pump is operating under cavitation or low flows.• Standard equipped with pumping ring.CDR FC 35SINGLE INTERNAL SEAL TAPERED SEAL CHAMBER• Suitable to work with low / moderate dirty corrosive liquids.• Easy maintenance thanks to the semi-cartridge design.• Extremely abrasion-resistant SiC seats, no metal parts in contact with the processed liquid and a wide range of options allow the FC seals to be the best solution for every application.• In case of liquid crystallization due to air contact, CDR offers plan 62.MECHANICAL SEAL• Wide choice of sealing arrangements for maximum sealing flexibility.• The CDR mechanical seals, FC series, have been developed for difficult operating conditions, hazardous and corrosive medium.• CDR FC-35 Single mechanical seal (Lined PFA or PP ).• CDR FC-TC35 Double cartridge mechanical seal (Lined PFA ).• Other mechanical seals can be adapted on UCN pumps, from single seal up to double back-to-back cartridge sealing system.SHAFT• The special design of the shaft guarantees no weak point that could cause leakage; the impeller is fixed on the shaft with a long screw that pass through the shaft.• Rigid shaft designed for less than 0.05 mm shaft deflection increases the seal life.• Standard 400 series stainless steel shaft (1.4057) provides reliable power transmission and corrosion resistance at both the pump and coupling ends.RPompe S.P.A.FEATURESMICROCRYSTALLINE DIAMOND COATING TREATMENT ON MECHANICAL SEAL FACES• Lowest coefficient of friction and heat generation, even when lubrication is insufficient or under dry running condition• Universal chemical resistance• Increased service life• Virtually no wearing of the diamond coating• Significant energy savingsDOUBLE CARTRIDGE SEAL TAPERED SEAL CHAMBEREXTERNAL FLUSHEDSuitable to PLAN 52-53-54• Same applications as conventional double seal• Easy maintenance thanks to cartridge designCONVENTIONAL DOUBLE SEAL CYLINDRICAL SEAL CHAMBEREXTERNAL FLUSHEDISO 12756 –EX DIN 24960• Applications where no leakage to atmosphere can be tolerated e.g. hazardous, toxic, inflammable media• When pump is operating under cavitation or low flows• For dirty, abrasive or polymerizing products where media is unsuitable as a lubricant for inboard seal faces• Double mechanical seal such as CRANE 2N\\\\2N ,Crane 58U\\\\58USINGLE EXTERNAL SEAL TAPERED SEAL CHAMBERSuitable to PLAN 01• Single PTFE bellow seals designed for external mountings, available in various materials and/or brands, like Crane 10Twww.cdrpompe.itPAINTING COATING QUALITYThe metal surfaces are protected by a high performance three coating layers (240 micron )• Epoxy zinc paint• Epoxy amidic modified vinyl• Epoxy enamel paint or aliphatic acrylic polyurethaneAvailable upon request :EN ISO 12944-5 C5M and C5I protecting paint system grades.BEARING BRACKET FOR BARE SHAFT EXECUTION• Extra-Large Oil Sump design allows to get a large oil capacity.• Breather / filling plug on top .• Oil sight glass grants a proper oil level.• Large drain plug.• The bearing frame can be equipped with 3 different type of protections : Standard oil seal Labyrinth seal Non-contacting labyrinth seal• Constant level oiler (as an option).• Conditions monitoring (as an option).BEARINGS• Heavy duty ball bearings configuration to provide L10 bearing life in excess of 17,500 hours (up to 1.25 QBEP).• Frontal (impeller side) : one row roller bearings type with high radial load rating.• Rear (motor side) : pair of angular contact ball bearings with high axial load rating.UCN-BLMOTOR SHAFT LOCKING SYSTEM• Shaft collett design incorporates easy maintenance system and allows to use a standard IEC frame electrical motor.• Close coupled design saves costs for baseplate and coupling, granting same performances and reliability.Part listDIN Component Material102 Volute Casing PP lined \\\\ PVDF lined \\\\ PFA lined106 Suction Casing PFA210 Top Shaft Aisi 431230 Impeller PP llined \\\\ PVDF lined \\\\ PFA lined330 Bearing Bracket GS400344 Lantern GS400412.1 O-Ring (Casing) EPDM \\\\ FPM \\\\ FPM enc.
