Flow characteristics
PGP640 series flow calculation example: PGP640A0500 has a theoretical flow rate of 150L/min at 3000rpm, and the actual flow rate is about 142.5-146.3 L/min (volumetric efficiency 90%-95%)
PGP610/PGP620 flow parameters are not clear in the search results
Material and seal
Cast iron pump body mainly
Sealing options include high temperature resistant seals (H3), corrosion-resistant seals (E6), etc.
Bearing material optional ceramic coating (K3) for high wear conditions
Application scenario
High-pressure systems (such as hydraulic test benches) recommend high-pressure models such as PGP640A0800
Medium and low pressure systems (such as machine tool hydraulic stations) can be selected PGP610A0300/PGP640A0300
The chemical/petroleum industry needs to choose sealing materials according to the characteristics of the medium
- Summary of technical characteristics
High pressure capacity: The full range supports continuous working pressure of 275bar, and intermittent pressure can reach higher
Low noise design: PGP620 series optimizes pressure pulsation through 13-tooth gears
Modular interface: support flange/thread connection, adapt to different system requirements
Special functions: Some models support flow adjustment (VT6T4), dustproof design (NS5), etc.
For more detailed size, weight or specific model parameters, it is recommended to contact Parker’s authorized agent directly to obtain the technical manual.
