What is slurry piston pump?YB series ceramic piston pump have been studied for transporting thick slurry to the filter press or spray-driers. The ceramic plunger pump is formed by: two pistons, run by two hydraulic cylinders; suction and delivery valves which can be easily disassembled for rapid inspection or for cleaning the pump; an air accumulator; a control pressure gauge; a valve to adjust the working pressure at any value (within the fixed limits), and a safty valve(Referring to Map2). The pistons are coated with sintered alumina (This special coating guarantees long life and resistance to the high abrasive action of the liquids) and equipped with gaskets made of special wear resistant material with a low coefficient of friction. Slurry piston pump runs stable, and has low noise, high pressure, low pressure fluctuation, small size, light weight, convenient operation and maintain, installation, long life span and so on . Mud plunger pump is mainly applicable in transfer slurry to various kinds of spray-driers, also in long distance supplying slurry, clean(dirty) water and coal slurry (or other suspensions) to filter press. Presently, YB series oil pressure piston slurry pump has five model:YB85, YB120, YB140, YB200, YB250, YB-300, the flux is 3m³/h ～40m³/h, the pressure is 0-2.0Mpa.

Hydraulic Oil For Filter PressHydraulic oilName Grade Working TemperatureAnti-wear hydraulic oilL-HM32(46)-5℃～80℃Low-temperature hydraulic oilL-HV(S)32 (46)-20℃～80℃ 1. The manufacturer of filter press dose not supplies the hydraulic oil. User provides it himself and make sure it’s cleaned.2. The hydraulic oil of chamber filter press should be used under the corresponding temperature, if the temperature is too low the viscosity will ascend, if the temperature is too high, the viscosity of the hydraulic oil will descent.3. Ways of adding the hydraulic oil of hydraulic filter press and the volume       When adding the oil, please use the oil filter vehicle to add the clean hydraulic oilfrom the air cleaner. For the oil tank is limited, the oil will overflow by one-time adding. Please do it by following steps: when the filter press is not under operation, first: add the elementary oil, then open the press, when closing, add the oil for the second time. For different models, the cylinder diameter, the stroke are different and the oil tank volume are also different, please noted.
