Can a cartridge-type condensate pump experience cavitation?
Thread Content
Design parameters: Operating parameters: Model 80LDTN-40×5; Inlet pressure: -0.065 MPa; Flow rate: 15 m3/h; Outlet pressure: 1.5 MPa; Head: 175 m; Flow capacity: 8 t/h; Efficiency: 58%; Water temperature at the pump inlet: 55°C; Rotation speed: 2900 r/min; Height of the liquid level above the pump inlet: 3 m. There are 2 elbows, 1 gate valve, and 1 filter at the inlet, with a pipe diameter of DN150. NPSH: 0.72 m; Valve opening degree at the pump outlet: 22%-35%
Theoretically, there are no issues with these industrial conditions; pay attention to the exhaust from the machine before starting it up.
The condensate pump uses a sack-type design – what a luxury; normally, just venting the air is sufficient
