About Dri-Prime


‘Dri-Prime’ relates to the process of when compressed air is blown through a jet into a tapered tube to create a vacuum. Air from the pump casing and suction line is drawn in with the compressed air and exhausted to the atmosphere. As the water starts to replace the air this automatically primes the pump.

All Diesel Pumps End suction pumps have automatic Dri-Prime, features and uses.

Here are just some of the features and benefits below:

  • A fully automatic self priming pump

  • Handles air/liquid mixtures
  • Rapid priming and repriming in snore conditions
  • Solids handling
  • No moving parts in priming system; no need for floats and no complications
  • Operation by unskilled personnel
  • Simple maintenance; can be carried out in the field by one man
  • For dewatering, sewage, sewage sludge, industrial slurries and drainage, and in scavenging situations
  • Electric driven versions are available, either with built-in compressor or separate air supply system to operate the priming systems
