In general, 80 to 100 mesh (150 to 180 m) filters are recommended. When transferring a coagulable liquid, take measures to prevent it from coagulating in the pump. Please contact SMC sales office for the use of slurry. Take countermeasures to prevent the operating fluid from getting onto the body of the process pump. 3.

Precautions to observe when transferring slurry Basically, it is not recommended to transfer slurry because this will result in seating failure and wearing of the check valve and accumulation of particles.

As a guide, the appropriate filtration is 80 to 100 mesh (150 to 180m). When circulating coagulable fluids, handle them carefully so that they do not coagulate in the pump. Flammable fluid cannot be used with the process pump with built-in solenoid valve (PB1011A). Do not use in an environment where flammable fumes are present or where falammable liquid may get stuck to the product.
Eliminate the foreign matter by using an appropriate filter (strainer).As a guide, the appropriate filtration is 80 to 100 mesh (150 to 180mm). When circulating coagulable fluids, handle them carefully so that they do not coagulate in the pump.
