JN315 Series

Reciprocating plunger pumps for industrial cleaning, ship hull descaling and water injection

Max. pressure: Standard 65 MPa; ultra-high-pressure version up to 120 MPa
Max. flow: 1230 L/min
Dimensions: 2170×1826×1012 mm

JN315 ultra-high-pressure water injection pump is a new-generation product developed based on over thirty years of experience in manufacturing high-pressure plunger pumps. It fully incorporates extensive user feedback and advanced international design concepts, combined with Juneng’s expertise in industrial processing, to deliver a carefully engineered solution for demanding applications.

The pump adopts a low-speed, long-stroke design philosophy and features comprehensive optimization of valve assemblies and plunger sealing structures. Both the power end and the hydraulic end have been innovatively upgraded, significantly enhancing the pump’s ability to convey abrasive media. These improvements greatly extend seal service life, reduce maintenance frequency, and lower labor intensity, supporting sustained improvements in operational efficiency.

Application Scenarios

The ultra-high-pressure water injection pump is suitable for:

Jet cleaning
Metal cutting
Ship cleaning
Rust removal
Cleaning of condensers, heat exchangers, and reactors in chemical plants, sugar plants, and power plants
