Lime slurry pump is the kind of heavy duty centrifugal pump designed and engineered  for pumping liquid containing solid particles. The lime slurry pump can increase the energy of a solid-liquid mixed medium by the action of centrifugal force (rotation of the pump impeller ), that is, a device that converts electrical energy into kinetic energy and potential energy of the medium. DS series lime slurry pump designed and manufactured by OCEAN Pump comprehensively applies the advantages and innovations of similar products at home and abroad in hydraulic design, structural design and wear-resistant materials. It has the characteristics of high efficiency, energy saving, low vibration, low noise, reliable operation, long service life and convenient maintenance.The comprehensive performance of the lime slurry pump is at the domestic leading level, and the most efficient index of pumps is at the international advanced level.

Lime Slurry Pump Design

1.Lime slurry pump case with internal and external double layer metal  structure.

2.Lime slurry pump case centrally split in vertical direction.

3.Discharge outlet can be assembled at 8 different positions with an interval of 45°.

 Seal Type

1.Specially designed expeller seal is suitable for used on a single-stage pump or the first stage of pumps operating in series, however normal pressure clean water or grease may be used for lubricating the packing seal when the pump is shutdown.

2.Optimized packing shaft seal is suitable for used in the second and more than second stage pumps working in series, with sealing water indispensable.

3.Strong mechanical seal is suitable for industrial and mining enterprises with relatively clean environment, need to seal the cooling water.

 Impeller Type

1. Closed impeller features high abrasive resistance, and high efficient.

2. Opened impeller features big flow passage, good for pass through the big particle.

DS series lime slurry pump is the ideal pumping machines to transport abrasive slurry containing solid particles, such as processing concentrates and tailing, ash removal from power plants, coal slurry and heavy medium coal preparation in coal preparation plants, and slurry transportation in coastal river mining operations. The maximum weight concentration of the slurry that can be treated is about 45% mortar and 60% pulp. DS series lime slurry pump is mainly used in such industries as coal washing, electric power, metallurgy, mineral processing, building materials, chemical and other industries.

One customer from Dongying was using a DS 250-75 lime slurry pump produced by other supplier, supporting 250 KW motor. Inlet diameter of the lime slurry pump is 10 inch / 250 mm, outlet diameter is 8 inch / 200 mm, discharge distance for 5 km. In the using period, the customer found that the lime slurry pump impeller wore quickly and had many cracks. It was also leaking and could not be used anymore.
On December 23, 2018, the customer contacted our company. Through communication, we found that the sand suciton pump type labeling parameters were incorrect. The actual parameters of the lime slurry pump type are much smaller than the marked parameters (Flow capacity is 1100 m³/h , Pump head is 50 m), there are problems in processing and assembly accuracy, especially there is no dynamic balance on impeller, this causes the impeller and the rear guard are easily attached together, which exacerbates the friction and the damage is relatively fast.
At that time, it was winter and the temperature was below zero, stopping the pump for a long time would cause the pipeline to freeze, this led to damage easily and reduced the service life of the pipeline. Our engineers suggested the customer reducing the frequency first in order to reduce the speed of the lime slurry pump. The lime slurry pump only pumped water to ensure that the water in the pipe flowed. On the other hand, the assembly workshop of OCEAN Pump immediately assembled a 12-inch high quality lime slurry pump (DS 300-75) and the supporting base. Because the lime slurry pump belongs to double pump casing series, it requires pressure and water leakage test. The test ensures that the inner pump casing, the front and rear guard plates are well sealed and leak-free. After overtime work, the commissioning was completed at 10:00 pm on December 23, 2018. The high quality lime slurry pump would arrive at the construction site at 8:00 on the 24th.

12 inch High Quality Sand Suction Pump (DS 300-75) Performance Parameters 

On-site Installation and Commissioning for High Quality Sand Suction Pump
Our sales manager and after-sales installation engineers drove to the customer’s working ite at 3 am on December 24, 2018, arrived at the site at 7:30, and started to install the lime slurry pump.
1.Stop the high quality lime slurry pump and booster lime slurry pump on board and discharge the water in the pipeline.
2.Temporarily raise the inlet pipe and the discharge pipe of the booster lime slurry pump to ensure no water flow and save drainage time.
3.Remove the original lime slurry pump DS 250-75, and hoist the original 250 KW motor to the 12 inch high quality suction pump installation base of our company, and start to adjust the concentration of the motor and mud pump and fix it.
4.Because the original pump type inlet is 250 mm and the outlet is 200 mm, and the new high quality lime slurry pump type inlet is 300 mm and the outlet is 250 mm. The imported and exported reducer tube is installed at the original pipeline.
5.Install a new high quality lime slurry pump DS 300-75 as a whole, and debug the steering and connecting pipes. The customer’s previous lime slurry pump does not have an outlet vent valve installed. According to the site conditions, an exhaust valve is installed to facilitate air removal and reduce Cavitation of the lime slurry pump.
6.Start the high quality lime slurry pump and booster lime slurry pump for discharging on the dredger respectively, and adjust the power frequency of the booster lime slurry pump according to the outlet flow to achieve the best relay condition.The whole modification process was very smooth. The customer thanked our company for actively cooperating, avoided further losses such as freezing on the pipeline, and learned the matters needing to pay attention to the high quality lime slurry pump through the modification process. The customer lamented that it is necessary to look for the brand when purchasing the lime slurry pump. Look for the manufacturers, remember that the price is low, find some personal pump companies.
