From an operational point of view the stuffing box is different as it requires some leakage to ensure lubrication and to prevent heat build up. The mechanical seal box should be leak free.

Non-settling slurries consist of very fine particles that do not settle to the bottom of the pipe and do not settle for very long (i.e. weeks).

In harsh conditions with sand, sludge, rocks and mud, ordinary slurry pumps tend to clog, wear and fail frequently. But WA heavy duty slurry pumps are highly resistant to wear and corrosion, which means that the service life of our slurry pumps is better than other manufacturers' pumps.

Mixers can also help agitators when pumping very dense particles. In applications where the tank is small and/or where pumping is desired to lower the water level in the tank, a slurry pump with an internal cooling system should be considered to avoid overheating of the stator (when the water level gets low). When pumping sediment from a dam or lagoon, consider the use of a raft unit, which is a submersible device. Agitators are recommended, as well as one or more mixers that can be mounted on the raft or pump to resuspend particles for successful pumping of particles.

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.

Why would maintenance personnel want to adjust a high-speed rotating impeller to a static lining component while the unit is running? Even if interlocking devices are used to prevent static and non-static components from coming into contact, how credible are these features and what are the implications for pump wear parts, bearings and motors if these two components come into contact?
