Full Technical Description

“DOSING PUMP 4140 1003 23 is a precision dosing pump used in controlled fluid injection systems on Epiroc and Atlas Copco drilling rigs. This dosing pump is designed to deliver accurate and repeatable volumes of fluid such as lubrication oil, additives, cooling agents, or treatment chemicals into hydraulic, pneumatic, or engine-related subsystems where exact dosing is critical for performance and component protection.

The DOSING PUMP 4140 1003 23 is manufactured with wear-resistant internal components, tight-tolerance metering elements, and seals compatible with industrial fluids used in mining environments. Its robust construction allows it to operate reliably under vibration, dust exposure, hydraulic oil contamination, and temperature variation commonly encountered on underground jumbos and surface drilling rigs. Stable dosing output helps prevent under-lubrication, over-injection, and system imbalance.

In operation, this dosing pump ensures consistent fluid delivery to targeted components, supporting smooth mechanical movement, reduced wear, and stable thermal behavior. A malfunctioning dosing pump may cause irregular lubrication, increased friction, overheating, or accelerated component wear. Early replacement helps maintain system efficiency and prevents secondary failures in pumps, valves, and rotating assemblies.

Installation should be carried out with attention to correct flow direction, mounting stability, and hose integrity. Periodic inspection of seals, flow consistency, and mounting fasteners is recommended as part of routine preventive maintenance on drilling rigs.
