Spindle Pumps

What is a Vertical Spindle Pump

Vertical Spindle pumps are also known as Vertical Sump Pumps. These pumps are a semi-submerged arrangement with its pump end submerged in the fluid and “bearing column” protruding out the fluid. At the top of the bearings column the mechanical driving mechanism such as an electric motor or engine is mounted. The bearing column contains the pump shaft which connects the mechanical driving mechanism to the pump impeller.

Different length Bearing Columns are available depending on the depth of the sump.

These pumps are able to operate without the need for mechanical seals. Standard electric motors can be used instead of specialised submersible motors.

Applications for Spindle Pumps

These units are used for handling slurries, liquids with abrasive solids in suspension and severe pumping problems such as corrosion, abrasion and temperature extremes in industry and mining.

Some of the smaller units which are also known as Regenerative Turbine Pumps have a different style impeller, and are used in industrial cooling and processing applications.

Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from which it exits.

Common uses include water, sewage, agriculture, petroleum and petrochemical pumping. Centrifugal pumps are often chosen for their high flow rate capabilities, abrasive solution compatibility, mixing potential, as well as their relatively simple engineering.

Submersible pumps consist of a pump body with a hermetically sealed motor attached to it. This allows the pump to be safely submerged in fluids without compromising the motor.

Submersible pumps are used in nearly all industries including Mining, Oil & Gas, Commercial, Food Processing, Industrial, Medical / Hospitals, Municipal, Petro-Chemical, Water Supply & Water Treatment, Residential.
