FCP Variable Motor Speed Controller replaces all traditional systems such as pressure tanks, pressure switches, automatic pump controls, flow switches which are no longer necessary.

FCP Variable Speed Controller is a new concept of 1 single phase Inverter for 1 Single phase pump motors.

The inverter is specifically designed for the single-phase motor pumps operation and it is suitable for all types of pumps including household pressure pumps and submersible bore pumps.

It does not depend on the flow or the pressure, but by a perfect feedback pressure control that guarantees substantial energy savings of up to 40% on respect to the standard on-off system. The energy saving is especially for medium flow, the most common use of the motor pump, combined by various security features which may not be possible in common appliances.

Soft starts and stops guarantee low current absorbing, a long-lasting pump motor, silent working quiet operation and the absence of water hammer.

The logic control unit of the FCP protects the system from null flow and dry-working conditions or other dangerous electrical or mechanical conditions.

All you will need to add is a gate valve on the discharge of the pump to isolate the pump unit from the system. It needs this so the pump can calibrate itself.

Turning the valve off will allow the pump to operate. The controller then “reads” the pump curve and sets itself to this. There may be minor adjustments needed like lowering the rating on the inverter by clicking the – button once or twice (from experience we have had to do this with most pumps to lower them below 3 BAR). Once calibrated the unit is ok then to operate at variable speeds.

For the single phase FCP, the pump needs to be 240V and the input starting current should be no greater than 40A.

Method 2

Using a submersible bore pump with a pressure tank

The 3-wire single phase motor is wired to a 3 wire controller/starter box. From the box it is wired to the pressure switch which is then connected to the mains power.

Pumping water from your bore to house using a pressure tank

A 75 Litre pressure tank is recommended for an average size household. It will allow approx 25 litres of draw off before the pump activates.

As a basis guide you can use the following:
Up to 1hp motor (say 30-40LPM) Use a 60-75L tank
Up to 1.5hp motor (60LPM) I would use a minimum of 75L tank
2hp motor, use a 112L tank
3hp motor, use a 180L tank
4hp motor use any size bigger than 180L

A 20/40 pressure switch is recommended with a 75Litre Pressure Tank. Turns on at 20 PSI and turns off at 40 PSI. It can be adjusted to turn off at 68 PSI.

A 30/50 pressure switch turns on at 30 PSI and turns off at 50 PSI. It can be adjusted to turn off at 88 PSI

When using a bore pump with a pressure tank, you don't want the pump to run frequently as it can burn out. To prevent this from happening, you can install a 1/4" swing check valve to the pressure tank. Drill a 3/16th hole in the check valve. When the tank needs to empty itself, the check valve will open up fully, but when the tank is being filled, water is going into the tank through a 3/16th hole and that allows for a longer run time of the motor.

The water pipe comes from the bore to the house. It has a T-piece in the line which is connected to the pressure tank, which is connected to the pressure switch.

Method 3

Using a small submersible bore pump with a pressure switch

The submersible cable from the pump is wired into the Control Switch. From the Control Switch it is wired into the Pressure Switch. From the Pressure Switch it plugs into a 240V electrical outlet.

The above method in this diagram can also be used to direct feed from the bore to the garden and/or house, where there is no water tank. If you are going to direct feed, please be aware that the pressure control switch is pre-wired and contains electrical power with a maximum of 10 Amps. So please only use with bore pumps up to 1Hp / 0.75kw
The water column between the pump and the highest point of use shall not exceed 15 m and the pumps should supply a minimum pressure of 2.5bar
In the case of using the control in points between 15 and 30m heights you are suggested to use model HYSK109B Pressure Control Switch. the adjustment of the starting pressure is made by the screw placed in the top of the control switch.

In this example the bore pump is set 18m below ground level. The wiring in the photos is the same as the illustration above.

Method 4

Using a larger (than 10A) submersible bore pump with a Pressure Switch

If you are using a larger bore pump eg: 1.5Hp / 1.1kw, 2hp / 1.5kw, 3hp / 2.2kw then you may want to include a contactor to the system. This can be done in many ways. The following diagram gives an example of a set up including a Contactor in the system. Please speak to an electrician for more info on this.

The water column between the pump and the highest point of use shall not exceed 15 m and the pumps should supply a minimum pressure of 2.5bar

Method 5

Using a Subdrive Constant Pressure System

The Subdrive Submersible system continuously monitors your water demands and provides constant pressure throughout your home and garden reticulation system.
Pump water directly and on demand from your bore / well to your house and or garden.
Turn on one tap or 6 taps, this system monitors and automatically adjusts the pump speed to adjust the flow accordingly and keeps the pressure constant.
