Lift Pump Not Priming at Nick Colon blog

Lift Pump Not Priming. When a positive displacement pump with no fluid in its pumping chamber is first started, the pumping chamber contains only air. The main objective of priming a pump is to remove the gas present. If your pump is undersized for the suction line, it will not be able to create the low pressure required to prime. Therefore, it is important to understand the suction lift requirements before you select your pump. The lift is too high for the pump’s speed or impeller diameter: It should kick close to whatever your idle pressure is then return to 0. After doing what needed to be done, i tightened everything back up, cracked open the 10mm bleed valve, and started on the primer. So, if the air or other gases are present inside the pump casing and suction line, it must be primed before. Next, turn key to start and the engine should. That’s how it’s supposed to work. Reduction in priming time mitigates the inevitable and rapid temperature rise for both the mechanical seal and priming chambers. The goal—and mantra—is to prime before you.
