Product Description
BME’s MiniCharger PCU represents the forefront of pumpable emulsion technology available for use in narrow reef mining operations.
The PCU is designed in-house for the delivery of BME’s range of Innovex UG emulsion formulations, increasing the safety of daily blasting practices through their UN 5.1 classification.
Application
The PCU is a positive displacement pump designed to work with BME’s patented ‘Closed Emulsion System’. The system eliminates waste while simultaneously delivering a predetermined mass of double salt emulsion and sensitising agent to each blasthole, sensitising the emulsion as it enters the blasthole.
The PCU is manufactured for rough underground conditions but is also light and compact enough to be carried and operated by mining personnel.
Primary Benefits
Supply of emulsion to the PCU is maintained through the use of BME’s patented ‘Closed Emulsion System’.
The patented automatic valve system in the re-useable emulsion bag prevents spillage, contamination of emulsion and maximises the service interval of the PCU.

Guidelines for Use
System Usage
BME’s PCU is designed primarily for use in the confined narrow reef mining environment, but is compatible with BME’s mechanised emulsion systems for confined blasting practices. In order to optimize the use of the PCU in confined environments the PCU can be operated by a single operator minimising labour requirements.
Safe Use
- Never fight explosive fires.
- Refer to Safety Data Sheet (SDS) for first aid information.
- All explosives must be transported and stored in accordance to relevant regulations.
- All explosives are classified as dangerous goods and may cause damage to property, personal harm, or death, if not used correctly.
- Always keep products away from sources of heat, sparks, flame or hot surfaces and avoid mixing with combustibles or incompatible materials.
