Today, there are still many areas where there is no electricity supply. Because there is no electricity, people in these places have difficulties in living, drinking water is difficult, and irrigation is difficult. The photovoltaic water pumping system has become the first choice for solving water problems with its advantages of easy installation, no manual compliance, low cost and zero carbon emissions.

The Philippines is an archipelago in Southeast Asia and a major market for DIFFUL solar pumps.
A Filipino customer sent us a video of his use after purchasing a DIFFUL solar pump.

Many swimming pools are open-air, and the dust in the air easily falls into the pool. Human skin also brings a lot of bacteria and viruses to the water. Excessive bacteria in the swimming pool water is the most likely cause of inflammation of the conjunctiva. The water in the swimming pool must be purified to ensure the health of the person.

When the home water pressure is insufficient, the booster pump can be used to solve the pressure problem. However, when faced with different booster pumps, how do you choose the right booster pump?

The screw pump is a rotary pump that relies on the volume change and movement of the mesh space formed by the pump body and the screw to transport or pressurize the liquid. The working principle of the screw pump is similar to that of the gear pump, except that the gear is replaced by a screw in the structure. The screw pump has a small flow and pressure pulse, low noise and vibration, and self-priming capability.

DIFFUL pumps sell a wide range of solar water pumps, irrigation pumps, submersible pumps, deep well pumps, surface pumps, swimming pool pumps and more. Oman is a sales market for the DIFFUL pump industry, and many Oman customers purchase DIFFUL solar submersible pumps.

Each pump has a set of performance curves. A flow value can be found for its corresponding head, power and efficiency values. We refer to this set of corresponding parameters as the operating point.
In the actual use of the pump, the operating point of the pump should coincide with the optimum operating point, or close to the optimal operating point, so that the pump can be kept in a high-efficiency operating area, thereby achieving energy saving.

In daily life, many people suffer from low water pressure. The so-called low water pressure is that when we need to open the faucet water, the faucet emits very little water. When we take a shower, the shower has half of the water holes and no water……This has greatly affected the quality of our lives.In fact, this problem is not difficult to solve, a booster pump can solve all problems.

Three parameters of pump selection: head, flow, power.
Head requirements:
The lift refers to the required lift, not the height of the lift. It is especially important to select the pump. The pump lift is about 1.15 to 1.20 times the lift height. If the vertical height of a water source to the water is 20 meters, the required lift is about 23 to 24 meters. (The flat pipe 20m consumes 1m head and 3 bends consume 1m head)

The self-priming pump relies on the high-speed rotation of the impeller to pump the low-pressure zone in the self-priming pump. Therefore, the self-priming pump must ensure that the inlet pipe does not leak. That is to ensure that the outside air can not enter the inlet pipe. Otherwise, it will not only affect the pumping efficiency, but also cause severe vibration and noise when the pump is working...

Submersible pumps often encounter problems such as oil leakage, low lift, low speed, Impeller does not turn, and low flow. Submersible pumps are widely used in agricultural irrigation and domestic water supply. Due to the long-term submersible work of the pump body, coupled with poor water quality in some areas and insufficient maintenance experience, the failure rate is high...

There are many reasons for the water leakage of the pump,mainly because the mechanical seal leaks.

Mechanical seals are also called end seals. The pump has apair of end faces that are perpendicular to the axis of rotation. The end faceis kept in conformity with the other end by the cooperation of the auxiliaryseal under the action of the fluid pressure and the compensation of themechanical external elastic force. And slide relative to prevent fluid leakage.
