Yamit Filtration products

The filters are designed and built in accordance with the principle of water flow through the cylinder screen openings while solid particles are trapped by the screen. These particles can be easily removed by opening the cover and washing the screen manually. The drain valve is used for releasing pressure before opening for maintenance. Applications: In-line control filters.

Water flows through the inlet along and through the cylindrical screen trapping the solids on the screen. The filter can be manually cleaned while still pressurized and without removing the screen. The operator cleans the screen by opening the flush valve and turning the handle, fully up and then back down. As a result the suction nozzles traverse the entire screen removing trapped debris. The whole process takes a few seconds.

Water flows through the inlet and through the cylindrical screen trapping the solids on the screen. The filter can be manually cleaned while still pressurized and without removing the screen. The operator cleans the screen by opening the flush valve and turning the handle, fully up and the back down. As a result the brushes traverse the entire screen removing trapped debris. The entire process lasts for just a few seconds.

The filter is equipped with a coarse screen that protects the finer screen from stones and larger particles. The coarse screen can be periodically clean manually. Automatic flushing of the fine screen is activated once the pressure differential (ΔP) in the filter reaches pre-determined value (up to 0.5 bar). During the flushing cycle, the flushing valve opens, pressure is released from the hydraulic piston and debris laden water is discharged through the flushing valve. Pressure in the hydraulic motor chamber and the dirt collector is significantly lowered causing the dirt collector nozzles move along and rotate cleaning the whole internal screen surface. The flushing cycle takes 5 seconds. The flushing valve closes at the end of the cycle, pressure reapplied to the piston, moving the nozzles back to their rest position, and the filter is cleaned. During the whole process water supply is uninterrupted.

The flushing valve opens and pressure in the flushing chamber and the dirt collector is significantly lowered resulting in a suction process via the suction nozzles to the dirt collector and from there through the flushing valve discharge. The electric motor simultaneously rotates the dirt collector and moves it along its axis. The combination of the vertical movement and rotation guarantees that the suction nozzles will cover the entire internal screen surface, efficiently cleaning the screen. The whole process takes 15 seconds. During the whole process water supply is uninterrupted.

Water enters the filter via the inlet and spreads evenly onto the media. Solids and organic materials are trapped within the media. The clean water passes through the media and flows out via the nozzles. The back flushing process is done by shutting the inlet of the filter and allowing the water to enter from the bottom, lifting the media and releasing the solids that exit the filter through the back flush manifold. This process can be controlled automatically.

Filter housing material of construction: Carbon Steel ST37.2. Exterior & Interior coating: electrostatic oven baked polyester-epoxy powder coating with a thickness of 150-200 micron. Connections: Victualic, Threaded socket and Flange.

Water enters the hydrocyclone via the tangential inlet which creates a spiral flow along the walls of the filter. The centrifugal force separates the waste and sand particles and pushes them towards the walls of the sand separator. Those particles gravitate downwards and into the sedimentation tank, while clean water moves upwards and exits through the top outlet. For the sand separator to operate correctly, the lead loss must remain between 2-5m. The separation efficiency is not affected by the accumulation of dirt in the sedimentation tank. The sedimentation tank is drained by opening a flush valve for a few seconds manually or automatically by timer.
