Function
NEPTUNE 1&2_EN_Ver.2.1_45/2014
Schematic function Neptune 1.
In this situation the position of the parts are The following:
The none return valve( A) is closed by the spring (B) as
there is no pressure on either of the sides.
The easy start ball valve (C) is pressed against the upper
seat by the easy start spring (D). The s/s spring presses
the s/s piston, and the Activation arm (E) is taken to the
front position, the micro switch (F) at the “switch on”
position, the motor (G) will start.
The handle (H) is released, No water flow from the nozzle.
Water flow: None
1. The none return valve (A) is closed by the spring
(B)as the pressure on the front side is still not high enough
to open it.
2. The easy start ball valve (C) moves a little from the
upper seat as the easy start spring (D) is pressed a little.
3. The s/s spring pressed the s/s piston, and the Activation
arm (E) is taken to the front position, the micro switch (F)
at the “switch on” position, the motor (G) is running.
4. the handle (H) is released, and no water flow from the
nozzle.
Water flows:
1. From the water inlet to the pump.
2. From the pump through the ball valve to the water inlet.
During building-up of pressure, the position of the parts
are following:
1. The none return valve (A) open a little because of the
high pressure from pump.
2. The easy start ball valve (C) moves to the lower seat as
the easy start spring (D) impresses more.
3. The s/s spring pressed the s/s piston, and the Activation
arm (E) is taken to the front position, the micro switch (F)
at the “switch on” position, the motor (G) is running.
4. The handle (H) is released, and no water flow from the
nozzle
Water flows:
1.From the water inlet to the pump
2. (Decreases during the process). From the pump through
the ball valve to the water inlet
3. From the pump through the none-return valve to the
high pressure hose.
