3″ × 3″ Threaded NPT Ports , Pump in Cast-iron With Steel 38NCD4 Shaft and Silicon Carbide Mechanical Seal
The centrifugal sel-priming pumps series JCS-S have been designed to be coupled to diesel or gasoline engines and electrical motors, through a flexible coupling. These groups of motor-pumps or electric pumps are then suitable for heavy duty application for this series of pumps are the following:
Building industry: Drainage of excavation sites, dewatering of floods. Water transfer to/from tankers.
Waste water treatment: Transfer of dirty and sewage waters, emptying of domestic or industrial drain wells.
Ship industry: Bilge dewatering, washing, water transfer.
Civil industry: Transfer of muddy, chemical liquids with solids and particles in suspension. Fire-fighting.
Sewerage system drainage.
Agriculture: Irrigation at low and middle pressure head. Oxygenation of liquids, (washing), sewage spreading.
MADE IN ITALY

Why does the pump primes automatically and is it called self-priming? We can give the reply to this question through graphic description of air and water route inside the pump. The air, represented by the moving impeller. By this movement the vacuum is created in the suction pipe and when the water, represented by the blue color, pushed by the atmospherical pressure fills the suction pipe, entering the separation chamber. The air-water mixture separates in the separation chamber and the air. being lighter than the water, goes up and gets out through the delivery port. The air-water mixture separates in the separation chamber and the air, being lighter than the water, goes up and gets out through the delivery port. The pump, as a matter of fact in presence of air or gas bubbles in the suction side gets un-primed but automatically driving out the air gets primed again.
