Product details
The self-priming arrangement uses gas-liquid mixing and separation with liquid returned within the priming chamber. Suction-pipe tightness, initial filling and the actual suction losses remain important; the catalog suction figure should not be interpreted as permission to start an empty pump or ignore vapour-pressure effects.
Published connection sizes are DN25–100, with 2,900 r/min speed and motor options from 1.1 to 30 kW. The temperature envelope is −20 to 120°C and the listed pressure limit is 1.6 MPa. These family values require a compatible lining, seal and selected curve for the actual liquid and operating temperature.
SELECTION NOTES
Specify the operating duty
Provide chemical composition, temperature, required duty, static suction lift and suction-pipe layout. Confirm initial-fill procedure, lining and seal compatibility and achievable priming time.
Published limits may describe different configurations within a series. Confirm that the required operating conditions are valid together.
