Maintenance Considerations for Peristaltic Pumps During Long-term Storage

time:2018-10-22 09:07:00from:JIHPUMP read:

        When using a peristaltic pump for a certain period of time and then storing it for an extended period, you may notice that the pump does not function as well as it did before. However, you may not be able to pinpoint the exact issue. Today, we will analyze how to maintain a peristaltic pump that has been idle for a long time.

Question: When we first purchased our peristaltic pump, it worked very well. However, after using it for some time, we stored it away and when we tried to use it again, it did not perform as well as before. What could be the reason for this?
Answer: This is mainly due to the fact that proper maintenance was not carried out during the long period of storage, resulting in the aging of some components within the peristaltic pump. If we store the peristaltic pump according to the correct procedures, we can greatly reduce the likelihood of these issues occurring.

Question: If we need to store our peristaltic pump for an extended period of time, what should we do?
Answer: If you plan to leave your peristaltic pump unused for a long time, please follow these steps to extend its service life:
(1) Check if there are any loose parts in the peristaltic pump, pipelines, or connections. Rotate the peristaltic pump by hand to see if it is flexible.
(2) Add lubricating oil to the bearing housing. The oil level should be at the center of the oil gauge, and the oil should be replaced or replenished regularly.
(3) Remove the water drain plug from the peristaltic pump body and fill with water (or slurry).
(4) Close the outlet pipeline valve, pressure gauge, and inlet vacuum gauge.
(5) Test the motor direction by briefly turning on the motor.
(6) Turn on the motor and once the peristaltic pump is operating normally, open the outlet pressure gauge and inlet vacuum gauge. Gradually open the valve while monitoring the motor load.
(7) Try to control the flow rate and head of the peristaltic pump within the range specified on the nameplate to ensure that the pump operates at the highest possible efficiency for maximum energy savings.
(8) During operation, the temperature of the bearing should not exceed 35°C above ambient temperature or 80°C.
(9) If you hear any abnormal noises from the peristaltic pump, immediately stop and check for the cause.
(10) To stop using the peristaltic pump, first close the valve, pressure gauge, and then turn off the motor.
(11) Within the first month of operation, replace the lubricating oil every 100 hours. After that, change it every 500 hours.
(12) Regularly adjust the packing gland to ensure proper dripping of fluid (ideally droplets).
(13) Periodically inspect the wear condition of the shaft sleeve and replace it if necessary.
(14) During winter months, after stopping the peristaltic pump, remove the lower water drain plug and drain the medium to prevent freezing damage.
(15) For long-term storage of a peristaltic pump, disassemble it completely, dry it thoroughly, apply grease to all moving parts and connections, and store it properly.
