Horizontal Slurry Pump

Slurry pump types

Three main types of pumps are used for slurry pumping:• Horizontal slurry pumps• Vertical slurry pumps• Submersible slurry pumps.

Horizontal slurry pumps

These types of pumps are often called dry mounted as the hydraulic end and the drive unit are located outside the sump. It is the main group of slurry pumps and they are available for a wide range of head and flow conditions and material options. These types of pumps normally use standardized electrical motors and seals. In plants where there is a risk of flooding, there can be reasons for replacing a horizontal pump by a dry-mounted, submersible, slurry pump.

Vertical slurry pumps

This type of pump can be subdivided into two main groups:• Tank pumps• Cantilever/sump pumps Tank pumps are considered as dry installed pumps. The sump is incorporated in the pump. Open sump and vertical inlet prevent air blocking and give smooth operation. There are no submerged bearings or shaft seals, but quite a long shaft over-hang from lower bearing to the impeller.
