PNJ rubber lined pump
Sewage Pump material:
According to different purposes, PNJ, PNJF type pump of pump shaft respectively made of quality carbon steel, nickel chromium steel sheath of wear-resisting rubber respectively, wear-resisting acidproof rubber and steel plate also, impeller for cast steel skeleton ( 25 PNJF type pump is cast iron skeleton), outer lining abrasion resistant rubber, wear-resisting, acid, rubber.
Sewage Pump sealing form:
PNJ, PNJF type pump has two different packing and pay impeller sealing structure (25 25 PNJF PNJ, only pay the impeller type pump seal structure). Sealing structure generally according to the packing supplier. If you choose to pay the impeller seal, when you order it must be specified. Sealed for impeller pumps, import infusion at no more than 5 m water column (25 PNJ, 25 PNJF type pump is not more than 1.5 m water column).
Sewage Pump features and use:
This series of pump is single stage, single horizontal centrifugal pump suction mud. The overflowing parts use rubber material, have a long life, apply to deliver corrosive slurry. Impeller sheath and impeller and guard board between them can be adjusted to keep high efficiency work. The shaft sealing form have impeller and packing two pay structure. When the impeller sealing structure, pay import perfusion shall not exceed 5 m high; The packing seal, should work into higher than 1 kg/cm2 pressure of the shaft.
