Big Capacity Split Casing Water PumpAdd to Inquiry
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.
Is widely used to refer to a double suction pump / pipeline pump where an impeller which is designed for producing high volume flows of potable and raw water without the prescence of solids. This is due to the impeller being of back to back design, where its design is like two impellers mounted together, mounted within a double volute.
Split casing pump designs have a single double impeller mounted on a shaft, with twin wear rings, twin mechanical seals or packing box, twin bearings and double volute.
Benefits of Split Casing Water Pump
High Capacity and Head
Split case pumps can efficiently deliver large water volumes with relatively high discharge heads. Their performance envelopes make them well-suited for water distribution, flood control, tank farm transfer, boiler feed systems, and similar duties needing high flow and pressure capabilities.
Robust Construction
These pumps feature sturdy casing, impeller, shaft, and bearing housing construction built for many years of rugged service. Their heavy-duty build quality allows split case pumps to reliably handle water, sewage, petroleum products, acids, abrasive slurries and more. Such robust construction also enables easy maintenance access when needed.
Flexibility in Arrangements
Split case pumps are available in vertical as well as horizontal arrangements. They can be base mounted or installed with additional supports for specialized services. Many configurations and custom options exist for drives, seal systems, materials of construction, and other features. This flexibility allows bespoke split case pumps tailored to specific applications ranging from raw water intake to mine dewatering and more.
Easy Maintenance Accessibility
The split casing design provides unmatched access to the pump internals - impellers, seals, sleeves, and bearings. Operators can inspect components and perform maintenance without needing to remove piping or disturb the pump foundations and alignment. Easy accessibility results in reduced downtimes for regular upkeep and any major overhauls throughout the long service life of a split case pump.
Types of Split Case Pumps
Vertical Split Case Pumps
Due to their design, vertical split case pumps have a minimal footprint compared to other pumps with similar capacities. However, they are not so popular as they tend to have lower efficiency. Vertical split cases are suitable for transporting high-pressure, high-temperature fluids.
Horizontal Split Case Pumps
Horizontal split case pumps are most common as they exhibit higher efficiencies (above 90%) and are more accessible to service. With a between-the-bearings configuration, these pumps are also stable at variable speeds and can work with various suction orientations.
Single-Stage, Horizontally Split-Case Pump
The most commonly used type is the horizontal split-case pump with a single impeller. This pump has a horizontally split casing, making it easy to maintain and repair.
Multistage, Horizontally Split-Case Pump
Unlike the single-stage split-case pump, the multistage split-case pump has multiple impellers arranged in a series and a horizontally split casing for easy maintenance. In addition, this type of pump is specifically designed to handle applications that require high-pressure pumping over long distances.
Vertical Split-Case Pump
A pump with a vertically split casing is a vertical split-case pump, which can be either single-stage or multistage.
Vertical split-case pumps are commonly used in applications requiring a compact design, such as building water supply systems or industrial processes. They are ideal for limited horizontal space, as they need less floor space than their horizontally split counterparts.

How Split Case Water Pumps Work
The components of a split case pump are impeller and pump casing. The impeller with multiple backward curved blades is fixed on the pump shaft and driven by an electric motor to rotate at high speed together with the pump shaft.
When the split case water pump started, the pump shaft drives the impeller to perform high-speed rotation, forcing the liquid prefilled between the blades to rotate, and under the action of inertial centrifugal force, the liquid flows from the center of the impeller to the outer periphery. The energy gained by the liquid flowing through the impeller increases the static pressure energy and flow rate. As the liquid leaves the impeller and enters the pump casing, the flow path in the casing gradually expands and slows down. Part of the kinetic energy is converted into static pressure energy and flows tangentially into the discharge pipe.
The split case pump shaft is supported by two single-row radial ball bearings. The bearings are installed in the bearing bodies at both ends of the pump body and lubricated with butter. Double suction sealing rings are used to reduce water leakage from the pump's pressurized water chamber to the suction chamber. The water pump is driven directly by the electric motor through the coupling. The shaft seal is a soft packing seal. To cool and lubricate the seal chamber and prevent air from leaking into the pump, there is a water sealing ring between the packings. When the pump is working, a small amount of high-pressure water flows into the filling chamber through the water seal tube to act as a water seal.
Components of Split Casing Water Pump
Impeller: The core part of the pump. The pump works on the liquid through the rotation of the impeller to increase its energy. The double suction pump used in our workshop has suction ports on both sides of the impeller and the working part of the impeller in the middle, that is, the pressure outlet of the liquid.
Suction chamber: Located in front of the impeller inlet. Function: evenly introduce the liquid into the impeller inlet, in this process, the energy lost by the liquid flow shall be small, and the uniform distribution shall be ensured when flowing into the impeller inlet.
Press out chamber: The part that collects the liquid with energy around the impeller and then sends it to the outlet pipe. It is also a component that converts part of kinetic energy of liquid into pressure energy and reduces the flow rate before liquid enters the outlet pipe.
Seal ring: Keep the proper clearance between the outer edge of impeller inlet and pump casing to reduce the leakage of water from high pressure to low pressure. Seal ring is also called mouth ring. It is generally made of cast iron and other wear-resistant metals. It can be replaced after wear.
Pump housing: Including pump cover and pump body. The function is to uniform water flow, change the direction of water flow, and convert kinetic energy into pressure energy. The parts with minimum friction loss are generally made of cast iron.
Pump shaft: Mechanical energy transmission parts, generally made of cast steel.
Shaft seal: To prevent the external air into the pump and the pump liquid leakage parts. The pumps in our workshop are in the form of mechanical seal, and the brands are Bergman.
Bearing: The main function is to support the pump shaft. Most of the pumps in our workshop are rolling bearings. The bearings are lubricated by grease, and generally 3 × lithium grease.
Clean the of the Split Casing Water Pump, and check whether there are scratches and burrs on the surface of the shaft. The packing box should be cleaned and the shaft surface should be smooth.
Check the shaft runout. The unbalance of the rotor runout should be within the allowable range, so as to avoid excessive vibration and adverse to the packing.
Apply sealant or lubricant suitable for medium on packing box and shaft surface.
For the packing packed in rolls, take a wooden stick with the same size as the journal, wind the packing on it, and then cut it with a knife. The knife edge should be 45 ° inclined.
The fillers should be filled one by one, not several at a time. The method is to take a piece of packing, apply lubricant, hold one end of the packing interface in both hands, pull it out along the axial direction, make it spiral, and then put it into the journal through the incision. Do not pull apart along the radial direction to avoid uneven interface.
Take a metal shaft sleeve of the same size material or lower hardness than the shaft of the packing box, push the packing into the deep part of the box, and apply certain pressure to the shaft sleeve with the gland to make the packing get pre compression. The preloading shrinkage is 5% ~ 10%, and the maximum is 20%. Turn the shaft for another circle and take out the shaft sleeve.
In the same way, load the second and third. Note: when the number of fillers is 4-8, the interfaces should be staggered by 90 degrees; two fillers should be staggered by 180 degrees; 3-6 pieces should be staggered by 120 degrees to prevent leakage through the interface.
After the last packing is filled, the gland should be used for compaction, but the pressing force should not be too large. At the same time, rotate the shaft by hand to make the assembly pressing force tend to parabola distribution. Then loosen the cover slightly.
Carry out operation test. If it can't be sealed, compress some packing; if the heating is too large, loosen it. It can be put into use only when the temperature of the packing is 30-40 ℃ higher than that of the environment.
