The power end of our pump is designed with utmost precision and durability in mind. The crankshaft box is crafted using ductile iron, a material known for its exceptional strength and resilience. This ensures the reliability and toughness of our pump, making it capable of withstanding tough working conditions without any compromise to its performance. Additionally, the crosshead slide is made using cold-set alloy sleeve technology, providing enhanced wear resistance and reduced noise levels. Furthermore, the compatibility with high precision allows for seamless operation and accurate output.

To guarantee a smooth and quiet operation, we have carefully fine-ground the gear shaft and gear ring surface. This not only reduces running noise significantly but also improves the overall performance of the pump. For optimum stability and durability, we have incorporated high-quality NSK bearings into our pump. These ensure that the pump operates seamlessly and reliably for prolonged periods, delivering consistent and exceptional results with every use.

Moreover, the crankshaft, an integral component of any pump, is manufactured using the highest quality American-standard 4340 high-strength steel. This provides assurance of a robust and long-lasting pump, capable of withstanding heavy workload and extreme conditions, therefore offering excellent value for your investment.

Our Horizontal Plunger Pump also caters to high flow requirements, making it an ideal choice for applications that demand large volumes of fluid. Whether you are in the industrial, agricultural, or commercial sector, our pump is versatile enough to deliver exceptional performance across various industries and applications.

One of the key features of our Triple Plunger Pump is its ability to provide fine grinding of gear shaft and gear ring surfaces, resulting in low running noise. This ensures a quieter operation, allowing for a more comfortable working environment. Additionally, the pump’s use of NSK bearings guarantees stable and reliable operation, enhancing its overall performance and longevity.The crankshaft of our Triple Plunger Pump is made of American standard 4340 high quality alloy steel. It undergoes a meticulous 100% flaw detection treatment, ensuring that only the highest quality components are used. The forging ratio of 4:1 further strengthens the crankshaft, resulting in a 20% increase in strength when compared to traditional 42CrMo crankshafts. This enhanced durability and strength make our pump ideal for demanding applications that require continuous and reliable operation.

Furthermore, the pump head of our Triple Plunger Pump adopts a high-pressure/water inlet split structure. This design not only reduces the weight of the pump head, making it easier to install, but also improves its overall efficiency. The split structure allows for better control of water flow, resulting in increased performance and reduced energy consumption.

In summary, our Triple Plunger Pump combines cutting-edge technology and superior materials to deliver exceptional performance in high pressure and high flow applications. With features such as fine grinding of gear surfaces, low noise operation, and a sturdy crankshaft made of American standard 4340 alloy steel, this pump is built to withstand even the most demanding conditions. The high-pressure/water inlet split structure of the pump head further enhances its efficiency and ease of installation.
