So This Is Christmas

Merry Christmas is such an infectious feeling I like to feel that way all year around.

So if you are visiting just before Christmas, just after Christmas or even here on Christmas day I am sure you will find something of interest for you and in the spirit of Christmas.

It may be said that Christmas is no longer a celebration but this must be spoken by people that have never had trouble closing their eyes on Christmas Eve in an expectation of what maybe left for them on the carpet under the tree.

I continue to look forward to the surprise on my Grandchild's faces to this day at Christmas events.

Merry Christmas - Merry Christmas - Merry Christmas

Role Of A Submersible Slurry Pump

By Ines Brennan


A submersible slurry pump is the kind of drain that is heavy and robust to a certain degree than the centrifugal pump. It is used to perform applications that are abrasive and tough. This centrifugal tap has its function in forcing out liquids that are clear. The drain refers to the kind that mainly transports solid materials.

Devices involved in the solid material transportation are referred to pumps. They are specifically given their names depending on the solid size they transport. The names could also change depending on the uses the devices are used for.

Pumps transport clay, silt, mud and sand ranging in the size of two millimeters. Gravel and sand pumps handle shingle and gravel transportation between the two and eight millimeter range. Gravel pumps could handle the transportation of fifty millimeters sized solids. Dredge devices are able to handle solids that measure up to and may exceed fifty millimeters.

Specific names given to these pumps could also depend on their applications and uses. Froth pumps for example handle slurry that are frothy and mostly in flotation. Carbon transportation devices are involved in offering smooth hydraulic transportation of the carbon in pulp and in leach circuits. Then there are sump pumps which contain submerged houses with dry drives and bearings. The devices are the ones that are wholly submersed including the drive and the housing.

Methods used in installing these pumps are various and rely on their different applications. The following are the various installation types, dry, semi-dry and wet. Dry installations are mostly applied on horizontal pumps. Their drives and the bearings are left outside while their wet ends are closed completely. In this case device ought to be free from any liquid.

Semi-dry type of installations is carried out using special configurations that are utilized in operations for dredging. The horizontal shaped pumps are installed with their wet ends flooded and their bearings too. These flooded bearings ought to have special sealing. Wet types of installations are used when a need arises for a drain that is fully submersed. In such kind of installations, the housing and the drive are flooded and hence would require special designs and sealing to be considered.

Determining the type of a drain to be utilized in a certain area depends on a number of factors. The type of application that a drain is meant for could be one of the considerations. Taking this into account could ensure that the pumps would be able to function in the various conditions present.

Advantages of these submersible pumps include the fact that they are able to offer a significant amount of the lifting power since they do not depend on external air pressure. They have mechanical seals which prevent the pumped fluid from entering the motor and causing short circuits. These kinds of pumps are relatively silent.

It remains crystal clear judging from the points raised above that indeed the submersible slurry pump plays a very vital role especially when it comes to matters involving solids transportation. The pumps should be built tough so as to handle their applications which are abrasive and tough.
