Product Introduction
ZJ series sand and slurry pump is a new type of anti-abrasion pump, belonging to axial, self-suction, single-stage, single suction, centrifugal slurry pumps. This series of pumps in the hydraulic design, structural design and the use of wear-resistant materials, combines the advantages of similar products at home and abroad as well as self-innovation, featured by high efficiency and energy-saving, small vibration, low noise, reliable operation, long service life and convenient maintenance. The overall performance ranks in the domestic leading level and most of the efficiency indicators in the international advanced level.
The pump can be widely used for transporting slurry with solid particles in the electric power, metallurgy, coal, building materials and other industries, such as hydraulic ash removal in power plant, slurry transportation in metallurgical concentrator, coal slurry in coal preparation plant and transportation of heavy medium, etc.
The maximum slurry weight concentration(Cw) of ZJ series sand and slurry pump: ash (slag) slurry and coal slurry is 45%; pulp and heavy medium is 60%.

Structural features
1. ZJ series sand and slurry pump: horizontal type
1) Pump head
The pump head of ZJ series pump comprises a pump casing, impeller and shaft sealing device. The pump head and the bracket are connected by bolt fastening. The outlet position of the pump can be rotated to eight different angles at the interval of 45 degrees for installation and use as required.The pump casing adopts double-shell structure. The outer layer is a metal pump case (including the front and rear pump shells) usually made of HT200 or QT500-7; the inner layer can be manufactured by high chromium alloy cast iron (including the volute, front and rear guard plates), or rubber (including the front and rear volutes).
The impeller consists of front and rear cover plates, blades and back blades. The blades, usually are 3-6 twisted blades. While the number of back blades are usually 8, distributed on the outside of the front and rear cover plates. The impeller(made of high chromium alloy cast iron) and shaft adopt screwed connection.
The shaft sealing device has three forms: auxiliary impeller and packing combination seal, packing seal, mechanical seal.
The auxiliary impeller and packing combination seal form is composed of stuffing box, auxiliary impeller, seal cage, packing, packing gland and shaft sleeve.
The packing seal form consists of stuffing box, spacer sleeve, seal cage, packing, packing gland and shaft sleeve.
The mechanical seal form comprises stuffing box, spacer sleeve, mechanical seal, gland and shaft sleeve.
2) Bracket part
The bracket part has two structures: horizontal split type and cylinder type.
The horizontal split bracket has two types: oil lubrication and grease lubrication. The oil lubrication bracket is mainly composed of bracket body, bracket gland, shaft, bearing box, bearing, bearing gland, nut, grease seal and other parts. 150ZJ and above pumps are also equipped with water cooling unit.
Compared with oil lubrication bracket, the grease lubrication bracket adds the embedded bearing cover and oil cup, and removes water cooling device.
The cylinder bracket adopt grease lubrication, mainly composed of bracket body, bearing body, shaft, bearing, bearing gland, oil seal, oil cup and other parts, which is only suitable for 200ZJ and below pumps with low power.
2. ZJL series sand and slurry pump: vertical type
ZJL series sand and slurry pump is primarily composed of impeller, volute, rear guard plate, shaft sleeve, bracket, support plate, shaft, bearing, bearing body and other parts.
The impeller, volute and guard plate are all made of high chromium alloy cast iron; the impeller and shaft adopt screwed connection, while the volute, bracket and bearing body use bolt fastening.
The pump shaft and motor can use direct drive coupling or belt drive. Use grease lubrication for bearings. This series of pumps has no shaft seal.
