The Heavy Duty Slurry Pump, also known as a sand dredge pump, is a specially designed industrial pump type. It is exclusively crafted to handle high-density materials, including sand, slurries, and sludge. Manufactured by Ocean Pump, the heavy duty slurry pump exhibits superior efficiency, reliability, and performance throughout its wear cycle.

1. What is A Heavy Duty Slurry Pump

A heavy-duty slurry pump is a robust and powerful piece of equipment designed to handle abrasive and corrosive slurries in various industrial applications. It is commonly used in mining, mineral processing, dredging, power generation, and other industries where the transportation of dense and abrasive materials is required.

The core component of a heavy-duty slurry pump is the impeller. The impeller is specially designed with different size diameter and a unique blade configuration to create centrifugal force and effectively transport the slurry. The pump casing, also known as the pump housing or volute, is constructed with wear-resistant materials such as cast iron or high-chrome alloys to withstand the erosive nature of the slurry. One of the key features of a heavy-duty slurry pump is its ability to handle high concentrations of solid particles in the slurry. These pumps are designed with a large internal passage and spacious impeller vanes to accommodate the passage of large-size particles without clogging or excessive wear. To ensure reliable operation and prevent leakage, heavy-duty slurry pumps are equipped with advanced sealing systems. This includes mechanical seals, gland packing, or a combination of both, to effectively seal the pump shaft and prevent slurry from entering the motor, diesel engine or external environment. Heavy-duty slurry pumps are available in various configurations and sizes to meet specific application requirements. They can be electrically or diesel engine driven, and the selection depends on factors such as the required flow rate, head pressure, and the characteristics of the slurry being handled.
