Horizontal Centrifugal Pump
The Kingda horizontal centrifugal pump boasts excellent abrasion and clogging resistance, ensuring stable and reliable operation even under the most demanding conditions, including when conveying large-particle fluids.
What is a Horizontal Centrifugal Pump?
A horizontal centrifugal pump, as the name suggests, is a centrifugal pump installed horizontally. Centrifugal pumps utilize the centrifugal force generated by the rotation of an impeller to drive fluids.
The advantages of this type of pump are its simple structure, reliable operation, and ease of maintenance. The horizontal structure makes the pump more stable during operation, reducing damage caused by abnormal vibrations.
Horizontal centrifugal pumps are commonly used to transport clean water, sewage, mud, slurry, etc., and are generally used in water supply and distribution systems, irrigation, industrial processes, sewage treatment, tailings, dredging, and other fields.
Horizontal centrifugal pumps are generally classified into horizontal single-stage centrifugal pumps, horizontal multistage centrifugal pumps, horizontal split-case centrifugal pumps, and horizontal centrifugal slurry pumps.
Due to their reliability, durability, high efficiency, and wide range of applications, they have become the most widely used type of pump. Today, with improved materials and optimized design, horizontal centrifugal pumps are becoming the choice of more and more companies.
Horizontal Centrifugal Pump Working Principle
The working principle of a horizontal centrifugal pump mainly involves four steps, with the impeller being the key component. It is the core of the entire energy conversion process and the very essence of a centrifugal pump.
- Drive Unit Start-up: The drive unit is typically connected to the pump shaft via a coupling, and the impeller is also connected to the pump shaft. When the drive unit (motor, diesel engine) starts, the impeller, connected to the pump shaft, rotates at high speed. At this point, the initial electrical energy is converted into kinetic energy, generating centrifugal force.
- Fluid Intake: As the impeller continues to rotate at high speed, a pressure difference is created at the pump inlet, causing liquid to continuously enter the pump. Under the action of centrifugal force, the liquid is continuously thrown outwards by the impeller.
- Kinetic Energy → Pressure Energy: Due to the volute shape of the centrifugal pump casing, the flow path of the fluid within the pump gradually narrows. While the flow velocity decreases, the fluid pressure continuously increases.
- Fluid Discharge: After a series of energy conversions, the fluid increases in pressure as it passes through the pump, eventually being discharged at the pump outlet. The pump outlet is connected to a delivery pipeline to transport the fluid to more distant and higher areas.
The Kingda KWP series horizontal centrifugal pump features an anti-clogging impeller and uses high-chromium alloy as the pump material, giving it advantages such as wear and corrosion resistance. It can easily transport fluids containing solids, sludge, and even fluids containing long fibers without clogging.
The KWP horizontal centrifugal pump is widely used in sewage treatment, agricultural irrigation, animal manure processing, high-rise residential water supply and distribution systems, energy, industrial wastewater, and mining.
Optimized Structure and High-Performance Materials
Each part is designed for efficiency and reliability
🔶 Materials: Horizontal centrifugal pumps are generally made of materials such as ductile iron, high-chromium alloy, stainless steel, ceramics, and rubber. Different materials are selected for different operating conditions and environments.
🔶 Impeller: The impeller is the core component of a centrifugal pump. Impeller types generally include open impellers, semi-open impellers, and closed impellers, and materials include cast iron, wear-resistant alloys, ceramics, and rubber.
🔶 Pump Casing: The pump casing is the pump’s load-bearing container. The quality of the pump casing affects the pump’s pressure-bearing capacity. Kingda horizontal centrifugal pumps are available in double-casing, single-casing, and split-case types.
🔶 Bearings: Bearings are the devices connecting the impeller to the motor or diesel engine and are an important component of horizontal centrifugal pumps. Kingda uses thickened, wear-resistant bearings to ensure a sufficiently long service life.
🔶 Seals: Horizontal centrifugal pumps have various sealing methods, including packing seals, expeller seals, mechanical seals, etc. Kingda’s unique KFSD sealing system effectively filters impurities in the water, effectively extending the seal’s lifespan.

Why Choose Kingda Horizontal Centrifugal Pumps
Common Problems with Ordinary Horizontal Centrifugal Pumps
Short Lifespan
Most standard horizontal centrifugal pumps are made of ordinary cast iron, which is not only prone to corrosion but also unsuitable for conveying fluids containing highly abrasive particles, severely shortening their service life.
Prone to Clogging
The impellers of ordinary centrifugal pumps are only suitable for conveying clean water. Once the liquid contains solids, fibers, or the viscosity of the liquid increases, clogging easily occurs.
High Cost
The materials used for the easily worn parts of ordinary centrifugal pumps are unsuitable for long-term fluid conveying, requiring frequent replacement of spare parts, which undoubtedly increases operating costs significantly.
Low Efficiency
Traditional horizontal centrifugal pumps cannot adjust frequency, speed, etc., according to operating conditions. When encountering unstable operating conditions, this results in a significant increase in power consumption and a reduction in pumping efficiency.

Horizontal Centrifugal Pump Curve Basic Information
X-axis: Pump Head
Y-axis: Flow Rate
The downward-sloping curve represents the pump’s speed curve.
The red upward-sloping curve is the efficiency curve; ensure the pump is within the efficiency curve’s range during selection.
The vertically upward-sloping dashed line represents the NPSH value; ensure NPSHA>NPSHR during selection.
How to select a pump from the pump performance curve?
1️⃣First, determine your required flow rate and head.
2️⃣Based on the head and flow rate, find the intersection of the X-axis (head) and Y-axis (flow rate).
3️⃣Determine if the efficiency and pump speed at the intersection are within the ideal range.

FAQ
Vertical centrifugal pumps are installed vertically, which saves space and allows for installation even in confined spaces, sometimes without requiring a separate pump house. However, vertical centrifugal pumps are more difficult to maintain and disassemble compared to horizontal pumps.
Horizontal centrifugal pumps are characterized by their stability, but their horizontal structure requires more space and may necessitate a separate pump house. However, they are simpler to maintain and easier to disassemble than vertical centrifugal pumps.
