DEEP WELL JET PUMP-1STG(NO ADAPTER) - DWP 1.0

You may have lost prime because
 the well has run dry, 
check valve has gone bad, 
foot valve has gone bad, 
or you have a leak in the suction pipe.

 If there is water in the pump, 
the internal jet may be plugged.
 Remove the jet injector from the 
pump and try to clear the obstruction 
with a coat hanger or something similar.

There are two types of jet pumps: 
those for deep wells and those for
 shallow ones. Shallow well jet pumps work similarly to 
submersible well pumps, but they only
 work for wells at a depth of 25 feet or less. 
Deep well pumps are more powerful, 
meaning they can function in
 wells as deep as 100 feet.

One of the most common reasons why the
 pump might be running,
 but you don't have any water 
going to your house,
 is that there is a malfunction
 with the pressure switch itself.
 If you take a look at the pressure tank, 
you will see a pressure
 switch at the bottom.

Another disadvantage 
is that HJPs have a low overall
 efficiency, typically between 
10% and 30%, depending 
on the fluid properties and 
the nozzle-throat ratio. 
This means that a lot of energy
 is wasted in the process of
 pumping the fluid mixture to
 the surface.

Series WJ pumps are portable for mobile applica- tion. Single phase pumps have a carrying grip and are supplied complete with power cable, plug and ON/OFF switch. – Jet Pump (WJ) – Installation and Operation instructions. Peripheral pumps, also referred to as regenerative pumps (also see Side channel pumps), are centrifugal pumps whose impeller (see Peripheral impeller) rotates in a largely concentric casing channel with an inlet and an outlet opening. Peripheral pumps operate by means of an impeller characterised by a large number of small dual-flow radial blades (with dual input) arranged along its peripheral area. The centrifugal forces inside the rotor generate a circulatory flow between the impeller and the casing channel. A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy. On the other hand, they have a better capacity. Another very striking advantage lies in the fact that these products are very inexpensive to purchase. For these reasons, they are widely used in the home to pump clean water , without abrasive particles or chemical liquids.
