Shijiazhuang Naipu Pump Co.,Ltd

• Brand NameNaipu Pump

We are offering centrifugal slurry pumps. Type zj(r), zjm and zjh pumps are cantilevered, horizontal, centrifugal slurry pumps.they are designed for the handling highly abrasive, high density slurries in the metallurgical, mining, coal, power, building material and other industrial departments etc.the pumps of this type also may be installed in multistage series. The frame plates for type zj(r), zjm pumps have replaceable wear-resistant metal liners or rubber liners.the impellers are made of wear-resistant metal or rubber.the frame plate liner and impeller for hh pump are adoptable of wear-resistant metal only. The shaft seals for type zj(r), zjm and zjh pumps may be adoptable of gland seal or expeller seal.the discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications.

We are offering Zjg Slurry Pumps. In order to meet the requirements on the development of the electric power, metallurgy and coal industries, our works has designed and developed series zjg(p)up-to -date generation slurry pump with large capacity, high head, multi-stages in series to remove ash& sludge and to deliver liquid-solids mixture, based on the experience of slurry pump design and manufacture for many years, and abstracting the research results of advanced technology from home and abroad. Cad modern design, super hydraulic performance, high efficiency and lower abrasion rate;wide passage , non-clogging and good performance of npsh;expeller seal combined with packing seal and mechanical seal have been adopted to guarantee the slurry from leakage;reliability design ensures long mtbf(mean time between events);the metric bearing with oil lubrication , reasonable lubricating and cooling systems ensure the bearing to be operated under the low temperature;the materials of wet parts have the good performance of anti-wearing and anti-corrosion ;the pump can be used for seawater ash-removing to prevent it from the corrosion of seawater, salt and mist and electrochemical corrosion;the pump can be operated in series with multi-stage within permissible pressure.the permissible maximum working pressure is 3.6mpa.the series of pump has the advantages of reasonable construction , high efficiency , reliable operation and easy maintenance.it can be widely used for handling the mixture containde of abrasive and corrosive solids in electric power, metallugy, mine, coal constructional material and chemical industry depatments.

We offer zjl and zjlr pumps are vertical, centrifugal slurry pumps submerged in sump to work.they are designed for delivering abrasive, large particle and high density slurries.these pumps have no need of any shaft seal and sealing water.they can also be operated normally for insufficient suction duties. wet parts of type zjl pump are made of abrasion-resistant metal. all parts of type zjlr pump immersed in liquid are lined with rubber outer liner.they are suited to transport non-edge angle abrasive slurry.

Ws dredging pumpis a new type of sludge pump researched & manufactured by our company, based on advanced technique introduced, aiming at the dredging and damming of the rivers and seas.it is widely agreed upon adopting dredging pump as main pumping equipment judging from the practice of treating rivers & seas at home and abroad.the means is consider to be a treatment of no-pollution to environmental protection, high efficiency and energy-saving.ws pump is single-stage single-suction cantilever horizontal centrifugal pump with advantages of light weight, good wear-resistant, super dredging performance , perfectly suited for the dredge on the whole construction , high multiple economy benefits and so on.it throughout meets requirements of the dredge to dredging pumps. The pump mainly consists of the pump head, gearbox specially for the dredging pump, high elastic coupling and supervisor system of the driving device for the dredge. Strongly wear-resistant casting alloy iron, whose hardness is not less than 58hrc adopted for the impeller, front liner and rear liner of wet parts.wear-resistant alloy steel is adopted for the casting with pressure-wear-resistant. Our company can select different kinds of material according to different media to meet the dredging requirement.

Type zjs(h) gravel pumps are designed for continously handling the most difficult higher abrasive slurries which contain too big solids to be pumped by a common pump.they are suitable for delivering slurries in mining, explosive-sludge in metal melting, dredging in dredger and course of rivers and other fields.type zjsh pumps are of high-head ones. construction of this pump is of single casing connected by means of clamp bands and wide wet-passage.the wet-parts are made of ni-hard and high chromium abrasion-resistance alloys.the discharge direction of pump can be oriented in any direction of 360.this type of pump possesses the advantages of easy installation, good performance of npsh and abrasion-resistance.
