The work noise of our most pumps is below 40dB, some of them even low to 23dB and 25 dB.

3 phase pump can endure more high working fluids temperature. Two phase working fluid temperature
should be lower than 70°C or 50°C, however, 3 phase pump can higher than 100°C or even 125°C.

Our 12V pump’s working voltage range is 5V~14V, 24V pump’s is 12v~30V. Some series pump’s working voltage range is more wider than this.

Material used for normal type pump is PA66+30%GF, PPS, material used for food grade pump is PPE. Material used for some automotive electric water pumps is Al alloy + PPS.

Suggest you operate the pump with fluids on its chamber. Since the pump motor will be burnt caused by the temperature rise due to poor heat dissipation.

We do have some models pump in stock. However, most of the pumps need to be placed an order to produce them for you. Since, there are hundreds of models in our product catalog, its really very hard for us to have all of them in stock.

Some of our pump with IP68 waterproof class can be used as a submersible pump. As all of our pumps are centrifugal pumps, therefore they do not have self-priming ability. So, you can’t use them as a self-priming pump.

People should install the pump with its inlet under the water level. For IP68 pumps, you can fix it submersible or outside of the water.
