<p>The pump comprises a pump housing consisting of a cylindrical immersion pump with an integral suction pipe, having on its outer cylindrical circumference a cylindrical single or multi layer woven filter element. The pump rotor in the upper part of the immersed unit is centrifugally self centring as a result of the tangential flow forces from the diffusion passages, and therefore makes no frictional contact with the interior of the pump housing. The unit, for use in connection with noble metal electro-plating is simple and requires little maintenance.</p> |
