1. Brief introduction about the order case of electric sand pump

On April 23th, 2019, the 8 inch electric sand pump 200 PNS-30 produced by OCEAN Pump was delivered to South Africa for dredging operations. This sand pump type was originally modified by a wear-resistant slurry pump, which inherited the high efficiency and resistance of the wear-resistant slurry pump. The advantages such as grinding, stable energy saving, deep suction depth make it suitable for sand pumping, dredging, tailing processing, relay transport and other engineering sites.

2. Electric Sand Pump Selection Process for customer

At the beginning of April 2018, South Africa customers visited OCEAN Pump factory. The customer undertook a section of river dredging project.  The excavator was used for river dredging and obviously felt high construction cost and slow construction progress. They hoped that OCEAN Pump selection engineer could recommend one suitable sand pump machine. Most of the sediments in the river are silt and sand, the excavator has cleaned up the weeds and garbage, the customers required a conveyor distance of 2,000 meters.

Through the on-site environment, OCEAN Pump recommended customers to use multiple vertical sand slurry mud pumps to work together, then gather sand and water mixture into an eight-inch electric sand pump to achieve long-distance transportation through relay. This dredging method has the advantages of high concentration and high efficiency. The only drawback is that the worker master needs to manually operate the water jet, and the labor cost is large. OCEAN Pump is designing an automatic water jet that will save labor costs after successful testing.
