Safeguarding pump from solid in suction for effluent or waste water pumping
Generally waste water or water base effluent get mixed with some foreign material. Sometimes fluid itself contains sticky suspended or floating lumps. If such solid content enters in pump’s suction line, it consumes lots of time for cleaning strainers and piping. If strainer damaged internally, it may damage moving part of pump itself.
This method will make pump safer with easy cleaning of solids attracted towards suction pipe.
Here in this method pipe line suction strainer avoided which may need to dismantle frequently for cleaning. Also pipe line suction strainers are having limited space for solid storage and filtration area. This system converts whole sump in to a large strainer with easy cleaning and wide range of sufficient suction flow to pump. Also it prevents dry running of pump by providing large and elevated surfaces for suction of water to pump.
A cylindrical rolled wire mesh basket is constructed with bottom closed and top open. The wire mesh size is selected as per permissible safe solid handling rating for the pump. This cylindrical wire mesh basket is having length slightly more than sump depth and highest water level.
This cylindrical wire mesh screen is fitted on suction pipe as shown in image. This covers bottom base and vertical height up to maximum suction height level.
This arrangement of screen provides a largest possible area for filtration. Pump will get suction from all surroundings. When screen gets chock up with solids, simply by low pressure water jet, it can be cleaned easily. No need for pump discontinuity for strainer cleaning. Pump life and performance will remain better.
The cost involved in this modification is very low even if compared with regular size strainer. The most attractive thing is chock up is easily visible from outside to act proactively for cleaning it.
