FA/TS Design
Sewage resistant pumps with big ball passage, strainer and pump foot.
They handle water with coarse solids, are robust, resistant against dry operation, handy and require nearly no maintenance. Removable strainer if coarse particles are to be pumped.
For three phase A.C., if required in explosion- proof design
Installation stationary or portable.
