Depending on the abrasive nature of the slurry, it is important to select the ideal seal. Slurry pump seals should have a hardened surface made of silicon carbide or tungsten carbide. Vortex pumps use patented seal technology that utilizes a double mechanical seal setup and a separate seal flushing system. This allows the sealing surface to be kept cool at all times without causing the slurry to overheat the seal and crack the surface.

Determine the size of the pump

Determine the perfect combination of slow pumping (to reduce wear) and fast pumping to prevent solids from settling and clogging.

Quenching is defined as the introduction of a neutral fluid (usually water or steam) into the atmospheric side of the seal to prevent the formation of solids that may interfere with movement or be used for other purposes.

When pumping slurry in wet sand applications, we must evaluate the abrasive particles flowing through the piping and then assess how they affect the slurry pump. If the pump is lined with poor quality rubber, the particles will not rebound effectively and, as a result, the rubber will begin to break down. The air shavings then begin to accelerate and negatively impact the efficiency of the pump, often leading to turbulence.
