WHY a KANU pump works
 
The pumps can dry indefinitely without damage.
No shaft seals or gland packing.

Infinitely variable flow & discharge pressure from 0 to pump's maximum by adjusting air pressure. One pump can fit a broad spectrum of applications.
Gentle non-shearing action.

If discharge is clogged or closed pump stops immediately; no power consumed, no wear - By opening discharge, flow starts automatically.
Operates submerged or with flooded suction.
Self-priming from a dry stat.
Pressure up to 100 PSI (7 bar)
No close fitting, sliding or rotating parts so can handle a wide of fluids with high Solid content.
Low internal velocity reduces wear.
Quick assembly and disassembly with split clamp bands.
Capable of priming at high temperatures.
Quit, steady discharge flow without use of pulsation dampener.
Safe for use in explosive environments.
No electrical hazards or costly motor and control equipment needed.
No pressure relief or bypass.
