What is radial split casing pump?
A split casing pump is a type of pump whereby the casing is split either perpendicular or radially across the shaft to allow easy access to internal pump parts for maintenance. The term is widely used to refer to a double suction pump / pipeline pump where an impeller which is designed for producing high volume flows.
What are the 3 commonly types of casing used in the centrifugal pump?
The three basic casing types primarily used for centrifugal pumps are the single volute, double volute and vaned diffuser.
How do you remove a pump casing?
These are the steps to follow:
- disconnect the electrical wires entering the electric motor cover.
- disconnect the circuit pump.
- remove the screws (1)
- uncouple the pump unit (2) and o-ring (13)
- unscrew the caps (3), making sure you secure the impeller using a soft belt, so as not to damage the paddles.
How does a split case pump work?
Split case centrifugal pumps feature a single double suction or two single suction impellers supported between bearings. The casing is split axially, with opposing suction and discharge flanges, greatly simplifying maintenance.
Why use split case pumps?
The design of the split case horizontal pump is what makes it stand out from others. They have a between-the-bearing design, which means that the impeller is supported by bearings on both sides. This allows for more significant support of the impeller and will enable it to turn more efficiently under stress.
What is pump casing?
The pump casing refers to the outside shell of the pump. It has to seal off the inside of the unit to the outside with respect to pressure and fluids. The structure of the casing differs depending on the type of pump.
What are the types of casing?
The five types of casing string are conductor casing, surface casing, intermediate casing, casing liner, and production casing.
What is a pump casing?
How many stages does a split case pump have?
A horizontal split case pump is a unique type of centrifugal pump whose casing is divided into two distinct chambers, which is different from inline or end suction pumps that are assembled with the suction nozzle, discharge nozzle, and casing in one chamber.
How is pump casing made?
Depending on the location, a pump casing can be made of cast or wrought iron, of chromium or duplex steel. Also some pumps can have a casing made of plastic.
What is a radially split casing pump?
Radially split casing pumps are quite different in that a pump has its casing opening across or perpendicular to the shaft. They are usually of back pull out design meaning for maintenance to take place a motor must be disconnected, then parts pulled out of the pump
What does axially split mean on a pump?
A split-case pump, properly installed, designed, and operated, can provide decades of service. Axially-Split Horizontally-Mounted Pump. Most split-case pumps are axially-split – meaning that the flange at which the pump casing separates is in the same plane as the pump axis.
What do split-case pumps lack that they make up for?
However, what they lack in low-cost flexibility they make up for in durability, efficiency, and dependability. A split-case pump, properly installed, designed, and operated, can provide decades of service. Most split-case pumps are axially-split – meaning that the flange at which the pump casing separates is in the same plane as the pump axis.
What are axially split pipes used for?
The diagram and images shown on this page are for the more run-of-the-mill axially-split variety that are used extensively in municipal water, industrial, oil & gas, and mining applications.
