The
R pumps are
self-priming positive displacement centrifugal pumps. The pump is normally placed dry above or aside the liquid. In these cases the suction line contains air. The self-priming pump will evacuate all the air. The vacuum produced as the impeller rotates draws air into the pump where it is mixed with the liquid already contained in the pump casing. The air/liquid mixture is driven to the discharge side where the air separates out and is expelled through the discharge port while the liquid, due to the higher gravity, falls back and is reused in the suction side through a small passage. When all the air has been evacuated from the suction line the liquid is pumped, even if air-laden. The high suction port keeps enough liquid inside the casing to allow re-priming any time. The non-return valve in the suction port avoids a backflow of the liquid and reduces priming times.
The
S pump present various advantages:
Self-priming.
Suction and discharge ports are available flanged or threaded.
Available with different type of engines (fuel or electric).
Check valve built-in that avoids the backflow of liquid from the discharge side.
Designed to prevent abrasion due to the passage of solids.Liquids matching with the
