Seeking manufacturers and models of soft water pumps used for polymer feeding
Thread Content
Dear teachers: Please kindly provide the manufacturer and model of the soft water pumps used for aggregate feeding. Our factory is currently using Hangjian pumps with a rotation speed of 2,900 revolutions per minute. The vibration level is extremely high during operation, and repairs cannot resolve the issue; the management is considering replacing the pump. I need everyone’s help! Thank you!
What about the other parameters of your pumps? We use those from Yantai Longgang, with 10KV motors that also operate at 2900 revolutions per minute. The outlet pressure is 17 kilograms, and the vibration is acceptable.
What is the cause of the vibration? Is the vibration coming from the pump itself, or is it caused by vibrations in the piping? ? ?
We’re using those from Da* Yuan Pump Industry, and the performance is pretty good
Can I say that I’m from Longgang, Yantai? ? ? Just finished testing the equipment on the 2nd floor of the company
Our company has 2 pumps manufactured by Da* Yuan Pump Industry Co., Ltd. The parameters are as follows: flow rate: 171 m3/h, head: 184 m, power: 160 kW, rotational speed: 2900 r/min. The vibration level measured a few days ago was around 20 mm/s. 2 units are from Yantai Hengbang Pump Co., Ltd.; parameters: flow rate: 171 m3/h, head: 180 m.
Our company uses pumps of the LZA100-400A model from Yantai Longgang; their power is 250 kw and the rotation speed is 2900 r/min. The vibration level during operation is not high, and the performance is satisfactory.
