Split case pump manufacturer
We manufacture split case pumps for large-scale water transfer, fire protection, municipal water supply, HVAC circulation, and industrial pumping projects. Our factory helps buyers select casing material, impeller size, mechanical seal, motor type, and mounting structure according to flow, head, system pressure, and operating environment.
Split Case Pump Advantages
Robust Casing Design
Split case pumps feature a horizontally split casing that allows inspection and maintenance without disturbing suction or discharge piping. We verify casing wall thickness, support ribs, and flange reinforcement to ensure stability under continuous operation and high-pressure conditions.
Motor Integration and Coupling
Split case pumps can be coupled with electric motors, diesel engines, or variable frequency drives. Motor selection includes voltage, power, frequency, and insulation class, while coupling alignment ensures optimal torque transfer and reduces vibration.
Efficient Impeller Matching
We select impeller diameter, number of vanes, and trim size based on flow rate, head, and operating duty. Proper hydraulic matching prevents cavitation, reduces energy consumption, and ensures smooth operation in municipal, industrial, or irrigation applications.
Mechanical Seal and Bearing Control
Pump shaft bearings, seal type, and lubrication arrangement are chosen according to fluid temperature, running hours, and vibration limits. This reduces maintenance frequency, shaft misalignment, and unexpected downtime in continuous-duty applications.
Custom Split Case Pumps
Fire Protection Pumps
Split case pumps are widely used for fire protection systems, including sprinkler and hydrant networks. Selection focuses on flow, system head, casing pressure rating, material compatibility, and compliance with local fire codes.
Municipal Water Supply Pumps
Municipal water distribution, booster stations, and treatment plants often rely on split case pumps. Selection depends on head, flow, solids handling, pipe size, and energy efficiency requirements.
HVAC and Industrial Circulation Pumps
Split case pumps are used in chilled water, hot water, and cooling circulation loops for large commercial or industrial buildings. Selection considers system pressure, temperature, noise, efficiency, and motor alignment.
Diesel-Driven Split Case Pumps
For irrigation, remote pumping, or temporary industrial sites, diesel engine-driven split case pumps are available. Selection depends on engine power, fuel type, torque output, coupling, and pump curve matching.
OEM Pump Projects
We support private-label split case pump assembly with logo, nameplate, paint, motor selection, connection type, and optional accessories. Technical confirmation can be based on drawings, samples, performance curves, or existing pump models.
Stainless Steel or Corrosion-Resistant Pumps
Stainless steel split case pumps are used where water quality, corrosion resistance, or chemical compatibility is required. Selection includes stainless grade, casing and impeller material, shaft sealing, and lubrication system.

COMMON QUESTIONS
Split Case Pump Manufacturer FAQs
Are split case pumps suitable for corrosive or abrasive liquids?
Split case pumps can handle mildly corrosive or clean liquids with proper material selection. Buyers must confirm fluid composition, temperature, solid content, and chemical compatibility before selecting a pump.
What affects split case pump lead time?
Lead time depends on pump type, casing material, motor, impeller trim, order quantity, packaging, and inspection scope. Standard cast iron electric pumps are faster; stainless steel, diesel-driven, or OEM models require longer preparation.
Can your factory customize centrifugal water pumps?
Yes, our factory can customize selected centrifugal water pumps for motor voltage, frequency, color, logo, packaging, connection type, and material configuration. Structural customization is possible only when the required parts, mold conditions, and MOQ support the project.
What information is needed before ordering a split case pump?
Provide flow rate, head, liquid type, temperature, pipe size, system pressure, voltage, frequency, and installation layout. Site photos or previous pump model can help with accurate selection.
How to select a split case pump manufacturer for bulk supply?
Confirm pump series, hydraulic coverage, material options, motor type, seal and bearing selection, assembly process, export packaging, and testing capability. For OEM projects, clarify logo, paint, and private-label requirements.
