JN200 Series

High-pressure triplex plunger pumps for industrial cleaning and water injection

JN200 series high-pressure water injection pump is a triplex plunger pump featuring a compact structure, small footprint, and high efficiency. The power end adopts forced lubrication, with the high-speed shaft and crankshaft driven by herringbone gears to ensure smooth and reliable transmission. This design reduces friction, enhances lubrication performance, lowers noise, and maintains a low power-end operating temperature, making it suitable for long-term continuous operation. Additionally, the hydraulic end of this pump is easy to disassemble, simplifying maintenance.

Application Scenarios

The water injection pump is suitable for various high-pressure cleaning applications, such as:

Ultra-high-pressure water jet cleaning
Metal cutting
Ship cleaning
Rust removal
Cleaning of heat exchangers, condensers, and reactors in chemical plants, sugar plants, and power plants

The pump can also be used to convey water, emulsions, or other water-like liquids.
