PNJ, PNJF rubber pump

PNJ and PNJF rubber pumps are single-stage single-suction centrifugal rubber-lined pumps (rubber-lined slurry pumps), which can transport various slurries without sharp solid particles. The maximum concentration of the transported slurry does not exceed 65% (by weight), and the temperature does not exceed 60°C. The two pumps have the same structure but different materials. PNJF pumps are specially used for transporting corrosive slurries.

  • Detailed Introduction

PNJ and PNJF rubber pumps are single-stage single-suction centrifugal rubber-lined pumps (rubber-lined slurry pumps), which can transport various slurries without sharp solid particles. The maximum concentration of the transported slurry does not exceed 65% (by weight), and the temperature does not exceed 60°C. The two pumps have the same structure but different materials. PNJF pumps are specially used for transporting corrosive slurries.

  • Features

The pump shafts of PNJ and PNJF rubber pumps are made of carbon steel and nickel-chromium steel respectively, and the flow parts are made of wear-resistant rubber and wear-resistant acid-resistant rubber respectively; the sealing forms are divided into two structures: packing seal and Fusylon seal (25 PNJ and 25PNJF rubber pumps only have Fusylon seal structure). The sealing structure is generally supplied as packing seal. If Fusylon seal is selected, it must be stated when ordering. When the pump uses Fusylon seal, the inlet filling height shall not exceed 5 meters of water column (25 PNJ and 25PNJF rubber pumps shall not exceed 1.5 meters of water column).
