Stainless Steel Chemical Pump Maintenance
Stainless steel chemical pumps can transport various media ranging from tap water to industrial liquids. The flow components of the pump are manufactured using a stainless steel plate stamping process, ensuring adaptability to different temperature, flow rate, and pressure ranges. These pumps are suitable for non-corrosive or mildly corrosive liquids and can handle media with temperatures up to 120°C. They are widely used in industries such as:
Water supply
Industrial pressurization
Industrial liquid transportation
Water treatment
Air conditioning cooling
Heating circulation
Irrigation
Maintenance Guidelines
Inspect for looseness: Check the pump, pipelines, and connections for looseness. Manually rotate the pump to ensure smooth operation.
Lubricate bearings: Add bearing lubricating oil to maintain the oil level at the center line of the oil gauge. Replace or replenish oil promptly.
Prime the pump: Remove the oil filling plug on the pump body and pour in priming oil (or slurry).
Close valves: Shut off the outlet pipe gate valve, pressure gauge, and inlet vacuum gauge.
Check motor rotation: Power on the motor briefly to verify correct rotation direction.
Start operation: After normal startup, open the pressure gauge and vacuum gauge. Gradually open the gate valve while monitoring motor load.
Optimize efficiency: Maintain flow rate and head within the rated range to ensure high-efficiency operation and energy savings.
Halt on abnormal noise: Immediately shut down the pump if unusual sounds occur and investigate the cause.
Shutdown procedure: Close the gate valve and pressure gauge before stopping the motor.
Lubrication schedule: Replace lubricating oil after the first 100 hours of operation (for new pumps), then every 500 hours thereafter.
Adjust packing gland: Regularly tighten the packing gland to maintain proper drip leakage (1-2 drops per second).
Inspect shaft sleeve: Monitor wear of the shaft sleeve and replace it promptly if significant wear is detected.
Winter precautions: In cold seasons, drain the medium through the lower drain plug after shutdown to prevent freezing damage.
Long-term storage: Disassemble the pump completely, dry all parts, apply grease to rotating components, and store properly.
