Notes when buying water pumps below 3.7kW and 50m³/h

• Determine the exact usage needs: It is necessary to calculate the flow rate (m³/h) and head (m) suitable for the system to choose a water pump with a well-matching capacity, avoiding choosing a pump that is too large causing waste or too small reducing operating efficiency.
• Choose the appropriate capacity: Although both belong to the group below 3.7kW, each model will have different performance and pumping capabilities. Choosing the correct capacity will help the machine operate stably, save electricity, and extend lifespan.
• Pay attention to manufacturing materials: Prioritize pump lines with cast iron, stainless steel, or copper pump bodies depending on the usage environment, to increase corrosion resistance, wear resistance, and ensure long-term durability.
• Check the power supply: Determine whether the current electrical system is 1-phase (220V) or 3-phase (380V) to choose the correct pump version, avoiding conversion or installation costs.
• Choose a reputable supplier: You should buy water pumps at Thanh Thai Motor, where there is a clear warranty policy and a technical team to support consulting, installation, and maintenance when customers need it.

Frequently Asked Questions

The pump runs but does not pump water, what is the cause?

This is a common error when the suction pipe is leaking, the pump has not been primed, the check valve is stuck, or the suction height exceeds the pump’s capability. You should check the pipe, prime it fully with water before starting, and clean the suction valve if necessary.

The pump operates but the pumped water is very weak, what should I do?

The cause may be due to excessively high head, too small piping, worn impellers, or unstable power supply. Checking pipe pressure, cleaning the impeller, and measuring voltage will help accurately determine the cause.

Why does the circuit breaker frequently trip when starting the pump?

The cause may be due to weak power supply, a circuit breaker with an inappropriate rated current, motor overload, or short-circuit phenomena.

Where does the noise or heavy vibration from the pump come from?

This phenomenon usually stems from unbalanced installation, worn bearings, unbalanced impellers, or air entering the suction line. It needs to be checked and resolved early to avoid affecting equipment lifespan.
