How the check the correct direction of rotation on a three phase jet pump.

The motor rotation direction may be inverted only in the three-phase motor pumps (230 & 460 volt). In single-phase pumps (115 & 230 volt) the motor always turns in the correct direction.

We recommend you read the instruction manual of the Jet, JetInox, JetCom (also available in our DNA software) for useful information for use, maintenance and installation of the product, including the procedure for checking the direction of rotation, which must be clockwise, as in the picture above
 

Pressure switches with adjustable differential

(Type G)

When setting the pressure switch, adjust the setting point on falling pressure

first, then the setting point on rising pressure.

• Setting point on falling pressure

The setting point on falling pressure is set by adjusting range-nut 1.

• Setting point on rising pressure

The setting point on rising pressure is set by adjusting range-nut 2.

The DAB Jet pumps can lift a maximum of 29ft.

It is always good practice to place the pump as close as possible to the liquid to be pumped.

The pump must be installed only in horizontal position. The internal diameters of the pipes must never be smaller than that of the mouth of the pump. It is advisable to fit a foot valve on suction.For suction depths of over 13 ft or with long horizontal stretches it is advisable to use an intake hose with a diameter larger than that of the intake aperture of the pump. To prevent the formation of air pockets, the intake pipe must slope slightly upwards towards the pump.
