- By increasing the size of the worm housing, the speed at which the media moves is reduced. This lower velocity translates into lower wear.

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.

method and level of design reach international advanced level. The company has the first-class pump performance

Some quench seals are planned to replace the tight fitting outlet restriction with a secondary seal and a top outlet that can be piped to capture the used quench fluid and drain it from the rotating assembly. However the principle is the same, we try to cool the seal rather than flush it in any way.

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