8. TROUBLESHOOTING ZERO OR INSUFFICIENT FLOW PRELIMINARY CHECKS Make sure that the plastic plugs have been taken away from the ports of the pump and that the pump is running (defective drive, damaged motor, etc., faulty transmission : broken coupling, sliding belt, worn or poorly coupled clutch, etc.). - Page 16 8. TROUBLESHOOTING (continued) MEASURING THE VACUUM PRESSURE (as close as possible to the pump inlet, inlet side). If the vacuum is high, e.g. higher than or equal to 6 to 7 metres WC (0.6 to 0.7 bara i.e. about 45 or 50 cm of mercury), this can result in pump noise.
- Page 17 8. TROUBLESHOOTING (continued) ABNORMAL NOISES These noises can be caused by hydraulic and mechanical sources. They can be distinguished by the fact that only the former disappear (or at least lessen) when air is allowed into the inlet pipe. HYDRAULIC NOISES These noises can come from insufficient product being supplied to the pump, or : - the rotation speed is too high for the installation conditions (increase of viscosity due to a change of product or a reduction of temperature, etc.).
