A sand pump is mainly used at construction sites and river construction sites to suck up sludge and gravel.
However, sand pump is equipped with a function that automatically prevents clogging, so they can be used safely even in areas with large amounts of sludge, gravel, or other impurities.
Most sand pump is more robust than normal pumps to prevent breakage when impurities are sucked into the pump.
Sand pumps are used at construction sites, drainage facilities, waste treatment facilities, and other water sites with large amounts of impurities, such as sludge, gravel, and sludge.
Various types are available, including large, small, submersible, amphibious, and high depth, and are used according to the application.
Smaller ones are used for temporary installation in civil engineering works and river construction projects to handle earth and sand, while larger ones can be used to collect sea sand, which is the raw material for concrete efficiently, from the sea.
The motor and pump are the same as those of a normal pump. The motor inside the pump rotates the impeller, which sucks up water and discharges it from the outlet side.
A shaft runs from the motor to the impeller, which transmits the rotation of the motor to the impeller.
The area around the motor is sealed to prevent flooding of the motor inside, and the suction area is protected by a mechanical seal.
Sand pumps differ from other pumps in that the impeller is made of high-chromium cast iron, which is the hardest material available, and each part has a thick wall for sturdiness. Also, a cutter for stirring is attached near the suction port.
The agitator cutter, made of high-chromium cast iron like the impeller, breaks into pieces large foreign objects that are sucked into the pump.
This allows the pump to suck in water mixed with sediment, gravel, sludge, and other sticky foreign matter without clogging the pump.
