Self Priming Diaphragm Pumps

Manufacturer: Caffini Pumps 

Our manufacturer produces diaphragm pumps series "Libellula" and "SuperMicrolib", which are reciprocating positive displacement pumps. The membrane is fixed to a connecting rod, and mechanically moved by a crank mounted on the speed reducer output. The displacement of liquid in the pump body, generated by the movement of the diaphragm, is controlled in suction and delivery by two check valves. In the suction phase, the diaphragm moving upward creates a vacuum that draws the liquid by opening the inlet valve. When the diaphragm moves downwards, the inlet valve close by gravity and at the same time, the liquid is expelled through the outlet valve, which opens at this stage.


Main Characteristics:

  • Indefinite dry-running capability.

  • Rapid dry self-priming up to a depth of 7 meters in a matter of seconds, (5 mt for SuperMicrolib series).

  • No seal or rotating part in contact with the pumped liquid.

  • Can be used where there are abrasive or acid fluids.

  • Wide passage for solid bodies.

  • Flow rate proportional to number of diaphragm pulses.

  • Quite simple, occasional maintenance.


  • Water Treatment Industry

  • Food and Animal Industry (giblet pumps)

  • Naval Industry (bilge pumps)

  • Textile Industry

  • Paper Industry

Self Priming Centrifugal Pumps

Manufacturer: Caffini Pumps 

We offer a Wide Range of Self Priming Centrifugal Pumps.


Main Characteristics:

  • Pump casing: first quality aluminum.

  • Volute and impeller are manufactured in cast iron for abrasion resistance.

  • Wear plate cast iron, easily replaceable.

  • Balanced impeller.

  • Suction and delivery flanged branches in aluminum, easily replaceable, internally female threaded BSP or NTP.

  • Mechanical seal in silicon carbide/silicon carbide grease lubricated.

  • Hand knobs to fix the cleanout cover and plugs to fill and to discharge water in the pump casing are in bronze.

  • Screwed tie-rods to close the cleanout cover are in stainless steel.

  • Amazing: self-priming even without check valve in the pump-casing.


Transferring heavily loaded water containing sludge, sand, and solids. The fast self-priming time, the handling of big solids, the high capacity and manometric head, and the quality are the main features of our centrifugal trash pumps.
