PFHM-ATEX pump with hydraulic drive

For use in explosive atmospheres (ATEX) in the mining industry

This high-pressure, hydraulically driven, multi-port pump is available with one or six pump elements in five sizes from 0.04 to 0.25 cm³ per stroke or camshaft revolution. (0.0024 to 0.0152 in³). The gear ratio between the hydraulic motor and the camshaft is usually 1:1.

The PFHM-ATEX pump's robust steel housing and reservoir with a breather valve allow it to be used in dusty environments. When used in conjunction with sequential control valves installed downstream in the pipeline, the pump can serve approximately 50 lubrication points. The reservoir, with a mixing device, is suitable for both grease and oil and is equipped with a locking device.

Technical characteristics and advantages

Robust design with standard spring return pump elements, ATEX compliant
Designed for 24/7 operation in challenging conditions
Adjustable speed and flow rate allow for economical lubrication settings, hydraulic drive without the use of electricity
Modular design with corrosion category C3 as standard or C5-M in accordance with DIN EN ISO 12944
The ATEX classification is used as a standard for use in gas, dust and mining environments.

Application areas

Mining equipment, including underground mining equipment
Hydraulically driven equipment
Vibrating screens and crushers in quarries
