Do horizontal self-priming pumps require a parameter for effective net positive suction head?
Thread Content
May I ask, Haiyou: does a horizontal self-priming pump require a parameter for effective NPSH, or does it only need the self-priming height parameter like a vertical self-priming pump?
As long as it is a centrifugal pump, there is a parameter related to the required NPSH; in the case of self-priming pumps, this is generally reflected in the pump’s suction lift.
No, only the inhalation height is required. If it is a horizontal centrifugal type, auxiliary equipment is definitely required, and the manufacturer has taken this into account during the overall design. You just need to provide the inhalation height
