CGV-L SERIES
The vertical CGV-L series is designed with high performance and reliability in mind. The compact construction with large material thicknesses provides an extremely strong and reliable pump that is also very easy to handle.
Material Combinations
With media-contacting parts in (PP-PVDF) and O-rings in (EPDM-FPM-FEP-FFKM), the pump is suitable for pumping acidic and alkaline media. The pump shaft is connected to the motor with an elastic coupling with an internal ball bearing and guided by a PTFE CG bushing or optionally in SIC/SIC.
Accessories
- Flanged connection at outlet
- Extra motor cover protection against water
- Filter on suction side
- Extension tube on suction side
Technical Design and Benefits
- Pump housing in extra thick PP or PVDF
- Impeller in PP or PVDF;partially open version for particle-laden fluids or closed impeller for clean fluids and high temperature applications
- Static guide bushing in PTFE CG (SiC upon request)
- Rotating guide bushing in Al2O3 (SiC upon request)Discharge pipe in thermoplastic
- Discharge pipe in thermoplastic
- Entire column made ofthermoplastic material
- Balanced shaft in 42CrMo4 carbon steel. Machined from one piece andcompletely covered with thermoplastic
- Extra thick PP plate
- Intermediate flangein aluminum, contains bearings and the elastic coupling, and separates the motor from the rest of the pump
- Heavy-duty radial ball bearings
- Elastic coupling that absorbs axial inaccuracies and allows motor servicing without removing the pump.
- Three-phase asynchronous motor, in accordance with IEC (NEMA upon request)
Mechanical Shaft Seals
Elastomer bellows seals
Mechanical shaft seals for mildly aggressive, clean, and non-particularly hot fluids. Static and rotating rings in SiC, springs and holder in SS316 not in contact with the fluid, elastomers in EPDM or FPM. Available as external type (B6E-B6EC), internal (B6I - B6IC - B6IH), or double mechanical type (B6EDF - B6EDFC).
PTFE bellows seals
Mechanical shaft seals for highly aggressive media and high temperatures. Static and rotating rings in three different material combinations (SiC-SiC, SiC-Al2O3, Al2O3-PTFE-C), PTFE bellows, springs and holder in SS316 (non-media contacting). Available as external type (JRS - JRS1 - JRA) or double mechanical type (JR2S - JR2S1 - JT2P - JR2A).
Sealing with O-ring in elastomer
Mechanical shaft seal for moderately aggressive, clean, and non-extremely hot media. Static and rotating rings in two different combinations (SiC-SiC, Carbon-graphite-SiC), spring and holder in Hastelloy C276, O-ring in EPDM or FKM. Available as an internal type (UMG – UMS) or double mechanical type (UM2G – UM2S).
