Applications & Installation
The DP series self-priming deep well pumps consist of an ejector unit and a centrifugal pump connected.The ejector unit can be lowered in a 4"Â diameter pipe of well. They are suitable to convey clean water and non-aggressive fluids. They are extremely reliable and simple to use and are suitable for domestic uses, for automatic distribution of water from small to medium size surge tanks and for boosting systems. In order to grant a correct counter-pressure, it is always advisable to install a foot valve with a strainer on the suction nozzle.

The rear wheel hub Ebike Motor of a power assisted E Bike, as the name suggests, is used in the position of the rear wheel of the bicycle to provide you with a type of rear thrust. It's like someone pushing you when you're tired. The history of using rear wheel hub motors on bicycles is also relatively long. It can be said that both quality stability and failure rate can be satisfactory. The technology of rear wheel hub motors is relatively mature, and many early power assisted bicycles used rear wheel hub motors. The price is also relatively affordable, and most of the motors used for power assisted bicycle locks in cities are rear wheel hub motors. Provided logistical support for the general public who are not proficient in maintenance and do not understand power assisted Ebikes. Our company's urban series lithium-ion powered bicycles all use this type of rear wheel hub Ebike Motor, which has high market sales and acceptance. If you haven't experienced power-assisted Electric Bicycles yet, it's best to purchase one for your spouse or children now.
