What causes short bearing life in Mazzoni 3.071.02.020?
To address short bearing life in your Mazzoni Water Pump: * Check the status of the keys, the flexible coupling or pulley for pump-motor coupling problems. * Change the oil following the instructions on the manual pump maintenance if the oil was not changed regularly. * Check the pressure if there is an excessive pressure of pumped water.
Why is my Mazzoni 3.071.02.020 Water Pump overheating and how to fix it?
If your Mazzoni Water Pump is overheating, it could be due to: * Pressure and/or number of revolutions higher than specified. Try decreasing the system pressure. * Incorrect or insufficient oil in the crankcase. Replace the oil with 15W/40 mineral type.
What causes pulsations and vibrations in Mazzoni 3.071.02.020 Water Pump delivery?
To address pulsations and vibrations in the delivery of your Mazzoni Water Pump: * Replace worn or dirty valves and seals. * Check the pressure in the discharge pressure accumulator. * Inspect or replace pipes/fittings for air aspirations and/or insufficient supply. * Clean or replace the filter if it's dirty or too small. * Decrease the water temperature if the inlet temperature is high.
What to do if Mazzoni Water Pump pressure is insufficient?
If your Mazzoni Water Pump is producing insufficient pressure, consider the following: * Replace the nozzle if it's too large or worn. * Check and clean the supply line, or correctly size it if blocked or undersized. * Install a suitable filter and replace the seals if there's excessive leakage due to abrasive substances. * Control vacuum in the supply (max 0.2 bar) if there is a cavitation for poor supply. * Calibrate, repair, or replace the pressure or safety control valve if it's not calibrated, worn, or dirty. * Check or replace pipes and fittings if liquid leaks from the delivery circuit. * Check the pressure with a new pressure gauge if the current one is out of order or not calibrated.
What to do if Mazzoni 3.071.02.020 Water Pump runs without noise or pressure?
If your Mazzoni Water Pump is running but not producing noise or pressure: * Check pipes and fittings in delivery if the pump is not primed and runs dry. * Check water tap if there is a lack of water in supply. * Check valves by disassembling them from the head if they are blocked. * Replace pipes and fittings in the supply line if it is closed and does not allow air in the pump to escape.
Why is my Mazzoni 3.071.02.020 Water Pump so noisy?
If your Mazzoni Water Pump is excessively noisy, check these: * Examine the status of the keys, flexible coupling, and pulley for pump-motor coupling problems. * Replace worn or damaged bearings. * Check and clean or replace pipes, fittings, and the filter if cavitation is due to supply pipes and/or undersized or clogged filters. * Replace seals and OR if they are worn.
How to fix noisy operation of Mazzoni Water Pump?
To fix noisy operation in your Mazzoni Water Pump: * Replace the bearings if they are worn. * Rebalance the rotor if there is imbalance or eccentricity of the rotor.
Why does Mazzoni Water Pump motor heat up excessively?
If the motor of your Mazzoni Water Pump heats up excessively: * Check the voltage in line if the power supply is too low or too high. * Reduce the applied load if there is an excessive load. * Check the voltage in line if there is an interruption of a phase. * Check that the fan turns regularly if there is an inadequate ventilation. * Consult the manufacturer if the cause cannot be identified.
How to stop oil leakage at the back of Mazzoni Water Pump?
If you notice oil leakage at the back of your Mazzoni Water Pump, replace the defective caps/seals if there is damage to the oil level cap, oil drain cap or seal between lid and crankcase.
How to fix oil leakage in the rear of the Mazzoni 3.071.02.020?
To address oil leakage in the rear of your Mazzoni Water Pump, replace the following: * Sealing ring. * OR. * Bearings, if there is damage to the oil level plug, oil drain plug or seal between the lid and housing.
