Product Description

8 Inch Sand Pump Small Portable Sludge Pump Submersible Slurry Pump Manufactures

Product Description

ZJQ submersible sludge pump is hydraulic machinery, the motor and the pump of which are coaxially submerged in medium to work. The overflowing parts of the pump are made from high alloy wear-resistant material, so the pump has good wear resistance and large flowing passage. It is applicable for conveying media such as sludge, ore slurry, coal slurry, sandstones containing big solid particles. The product is designed and manufactured by domestic and over sea advanced technologies. Besides the main impeller, the bottom of the pump is additionally provided with a set of agitation impeller which can spray the deposited sludge into turbulent flow, and therefore the pump realizes high-concentration conveying under the condition of no auxiliary device. The unique seal device can effectively balance the pressure inside and outside the oil chamber, so as to project the reliability of the mechanical seal to the maximum extent. The motor adopts various protective such as overheat protection, water inlet detecting projection, and can operate safely for a long term in harsh working conditions. The pump is applicable for pumping sand for building, silty sand, silt, tailing slurry, ore, iron sand ore, sediment in sewage treatment works, etc.   

The whole machine is dry submersible pump, and the motor adopts oil chamber seal mode and is provided with mechanical seal inside, so that high pressure water and impurities and are effectively prevented from entering inner cavity of the motor.
1.Besides the main impeller, there is the agitation impeller which can agitate the sludge deposited on the water bottom into turbulent flow and pump the sludge out.
2.The trans-flux parts such as the impeller and the agitation impeller are made from high-hardness high chromium cast steel, have wear resistance, corrosion resistance and strong drainage capacity, and allow big solid particles to pass.
3.The motor is submerged in water, is not limited by suction stroke, and has high   sludge suction rate and thorough desilting.
4.The integral device is simplified, needs no auxiliary stirrer device or ejector device, and has simple and convenient operation and low total investment of the unit.
5.The agitation impeller directly approaches the depositional surface, and controls the concentration through submerged depth. Under the condition of large medium proportion, an auxiliary device can be arranged to increase the concentration of the medium.

1.All water contact parts are all constructed with abrasion resistant materials - chromium alloy; so pumps have better stability & longer service life. 2.Unique mechanical seal device can prevent the electric motor from high pressure water and impurities; thus high suction efficiency can be ensured. 3.Except the main impeller, two or three of extra agitators can be equipped to the main pump body to help break and mix the sludge, greatly improve the work efficiency 4.Easy installation, operation and cost saving, no need additional vacuum pump or pump house.

Use Conditions
1.The power source is 50Hz/380V three -phase alternating-current supply, and the capacity of the substation transformator two to three times of the rated capacity of the motor.
2.The temperature of the medium cannot exceed 60ºC, and the medium does not contain inflammable or explosive gases.
3.The maximum weight concentration of the solid particles in the medium: the maximum weight concentration of the ash is 45% and maximum weight concentration of the slag is 60%.
4.The submerged depth of the unit is not more than 20 meters, and the minimum submerged depth takes submerging of the motor as reference.
5.The unit works in the medium vertically, and the working status is continuous.

Installation Instructions

1.Preparation before Installation
1)Carefully check whether the electric pump is deformed or damaged in the processes of transport, storage and installation and whether the fastening pieces and loosened or fallen off before starting.
2)Check whether the cable is damaged or broken, if yes, replace the cable to avoid electric leakage.
3)Check whether the power source device is safe and reliable and that the rated voltage should accord with the nameplate.
4)Use a megohmmeter to check that the motor stator winding cold ground insulation resistance should not be less than 50 MΩ.
5)Check whether the oil quantity in the oil chamber is appropriate and that the oil level of the unit in the vertical position should be flush with the oil filling opening.
6)Make sure that clear cold water is filled continuously when the submersible pump with the cooling shield is started, and make sure that the outlet is smooth and the cooling water flows in from one side of the lower end and flows out from the upper end of the other side.
2.Notices
After the pump is operated normally, please observe whether the voltage of the power source, the working current, the flow rate of the pump and the vibration of the pump are normal at any time. If one of the following conditions occurs, please immediately stop the machine to check:
1)The working current exceeds the rated current.
2)In the rated pump lift, the flow rate is reduced by more than 20% or the water outlet is discontinuous.
3)The voltage of the water power source is over high or too low.
4)The pump has obvious vibration or noise.
3.Installation Notices
1)Electrical connection: the electrical connection should be carried out by professional electrician according to the circuit diagram, the insulation resistance should be detected at any time in the installation process, and the motor insulation resistance should not be less than 50 MΩ after the installation is over. The pump is hung and subjected to inching turning, so as to observe its rotation direction, and the pump is rated clockwise if a person looks downward from the motor direction. If the rotation direction is wrong, please replace any two connectors of the three phase power supply.
2)Prohibit using the cable of the pump as a rope for installation and hoisting, so as to avoid dangers.
3)The pump should be vertically submerged in water, should not be horizontally placed and fall into sludge, and the power source should be cut off when the pump is moved.
4.Storage Notices
1)The electric pump should be placed into clear water to rotate for several minutes after being used for many times, so as to prevent sediment from remaining in the pump and ensure the cleanness of the electric pump.
2)The electric pump should be taken out from water if not used for a long term, so as to reduce the occasion that the motor stator winding is affected with damp and prolong the service life of the electric pump.
3)Under normal working conditions, the electric pump should be maintained after working for a year, the worn wearing parts should be replaced, the tightening status should be checked, and the lubricating grease of the bearing and the insulating oil in the oil chamber should be replenished or replaced, so as to ensure good operation of the electric pump.
