high quality high pressure gold dredge pump factory

Positive displacement slurry pumps with limited capacity to deliver high head are used to pump slurry through pipes with very high solids concentrations.

All manufacturers are consistently involved in product development in the long and short term. Customers should expect to benefit from these developments in a number of ways: increased efficiency, increased reliability, reduced operating costs, or a combination of both.

The first major requirement for >slurry pumps is to provide adequate service life. The erosive and corrosive effects of slurries, such as the impact of high velocity flow of liquid/solid mixtures, can be really challenging. In many applications, some of the solids in the mixture are larger than the particles normally specified; therefore, the pump should be able to pass through them without causing any damage or operational problems.

Dredge pumps are designed to transfer large quantities of fluids and solids.

Determine the operating parameters of the pump.

As wear is a function of speed, slurry pumps should be operated at the lowest possible speed; units typically run at 1,200 rpm or less. Often, direct coupling between the pump and a low-speed motor or other drive makes the most sense. On the other hand, many other applications favour gearboxes to meet the required speed and operating point. In services where variable flow rates are required, variable frequency drives are used to provide the necessary continuous speed variation.
