|Air-operated microsilica pump
|Conventionally, microsilica is transferred into the truckmixer drum by a submersible pump attached to a hose. It is a two man job with attendant risks due to usage of the truckmixer ladder; the moving drum; cable and hose tripping hazards; and manual handling of liquids and equipment.
Tarmac Northern North Area (Concrete and Mortar) has solved this problem by developing (in conjunction with Derwent Measurement Ltd) an air-operated diaphragm pump with 110 volt remote control facility.
