Pay attention to the location and installation direction of the pump, pipe and tank. It is recommended to contact our sales engineer to provide you with installation manual instructions.

It may be a mechanical failure of the pump, or it may be due to restricted suction pipes causing cavitation (noise). In case of abnormal sound, the water pump can be tested separately without connecting the pipeline system. If the noise is eliminated, it is due to the unsmooth system pipeline causing uneven exhaust, resulting in abnormal sound. If the water pump is tested separately and there is no dry running or noise, it needs to be sent back to TOPSFLO for quality analysis of the cause.

Firstly, always check the compatibility of the materials available against the fluid being pumped. It may be that more than one material is suitable for your fluid and selection could be based on the application type. If it is a simple transfer application with a clean less corrosive fluid, then the most cost-effective material will be best. However, if it involves more complex variables such as high temperature and the fluid is highly corrosive then other materials will need to be considered.

There are many benefits of sealing the pump in this fashion, including;
• A mechanical seal does not need to be regularly replaced due to wear and tear, this greatly reduces maintenance costs.
• A seal flush is not required for seal lubrication.
• The fluid is fully contained within the pump, this means there are zero chances of leakage.
This is a great benefit when handling hazardous and corrosive products.
