A quench plan, as the name indicates, is designed to quench or cool the seal. It is normally used if short periods of dry running are expected. As illustrated bellow, the fluid is introduced into the area between the back of the seal faces and the close fit exit on the drive side of the pump.

To reduce component wear, most centrifugal slurry pumps run at fairly low speeds - typically less than 1200 rpm. Find the optimum position that allows the pump to run as slowly as possible but fast enough to prevent solids from settling out of the slurry deposit and clogging the lines.

Flushing is defined as a fluid which is introduced into the seal cavity on the process fluid side, close to the seal face, and is normally used to cool and lubricate the seal face.

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.

Choosing the right pump for your slurry is critical to getting the most out of it. Basic pump components such as impeller size and design, materials of construction and discharge configuration must be considered to ensure that the pump can withstand the wear caused by abrasive slurries. Compared to low-viscosity liquid pumps, target=_blank title=Slurry Pump>slurry pumps are typically larger and often require more horsepower to operate because they are less efficient. Bearings and shafts must also be more robust and durable.
