Product Description

ZJ series slurry pump

Model: 80ZJ-A42

Brand: Guonai

Material: High chromium alloy

Application: Suitable for conveying high concentration slurry with strong abrasion or slurry with low concentration and high lift

Layout: Horizontal

Transmission type: DC Direct drive, Cr parallel belt drive, zvz upper and lower belt drive, CV vertical belt drive, etc.

Flow: 61-204m 3/ H lift: 14.4-70.4m speed: 700-1480r / min

Features and uses:
ZJ slurry pump is a single-stage, single suction and centrifugal slurry pump designed by our factory. The overflow parts of this series of slurry pump are made of high hard alloy cast iron with high wear resistanceCorrosion resistance, corrosion resistance and impact resistance, so as to improve the service life of the pump. According to the structure, the pump can be divided into horizontal (ZJ Series) and vertical (ZJL Series). According to the outlet diameter, the horizontal pump is divided into 350mm, 300mm, 250mm, 200mm, 150mm, 100mm, 80mm, 65mm, 50mm, 40mm and other specifications; The pump of each specification and diameter has different impeller diameter according to different head. The pump is suitable for electric power, metallurgy, coal Industrial industries such as building materials and chemical industry are mainly used to transport abrasive slurry containing solid particles, such as concentrate and tailings treated by concentrators and ash removal from power plants Slag, coal preparation plant conveying slime and dense medium coal preparation, coastal river mining operation conveying slurry, etc. The upper limit weight concentration of the slurry that can be treated is mortar 45%, pulp 60%; The transmission mode can adopt direct connection, belt, hydraulic, frequency conversion speed regulation and other forms, and can also operate in series or parallel according to the needs of customers.

Sealing form:
ZJ series slurry pump can adopt three shaft seals: auxiliary impeller and packing combined seal, packing seal and mechanical seal.
(1) Auxiliary impeller power seal: the auxiliary impeller seal uses the pressure seal generated by the impeller and the auxiliary impeller in series, and the packing or lip seal ring as the parking seal
seal up. When the positive pressure at the pump inlet is not greater than 10% of the pump outlet pressure, the single-stage pump or multi-stage series pump adopts this sealing form.
(2) Packing seal is a common form of shaft seal, which is suitable for various working conditions and can match with special packing such as tetrafluoroethylene packing and graphite packing
Material, which can be used under abrasive or high temperature conditions. It has the advantages of simple structure and convenient maintenance.
(3) Mechanical seal: advanced sealing technology is adopted, with good sealing effect. The container structure makes the installation and replacement more convenient, and different structural forms are suitable
Different working conditions shall be. The friction pair is made of high hardness ceramic or alloy materials, and the design and coordination of mechanical seal and sealing box conform to the medium flow shape
Therefore, it has high seismic resistance and can satisfy customers under various working conditions.
Features of pump body mechanism:
The pump body adopts inner and outer double-layer metal structure.
 the pump casing is vertically split.
The water outlet shall be installed and used at eight different positions at an interval of 45 degrees.

Hebei Guonai Electromechanical Device Co., Ltd. has mature experiences for many years on research & manufacture and application of slurry pump.Meanwhile based on technology intruduction,the perfect product series has been developed which covers full rage for application.Among them,series AH, ZJ,  ZGB, GH,SP series, etc. has wider usage especially.Through the apply in the industry such as mentallurgy,mine,electric factory and chemical industry etc,it has been proved that these products have advantages of reasonable construction,reliable operation and long service life etc which are welcome in consumers.
