Vega Pump Accessories
The Vega control equipment range is everything around the pump that makes it start, stop and last: float switches, automatic flow controllers, pressure tanks, pressure switches, gauges, connectors and replacement bladders. Most pump failures come from dry running and rapid on-off cycling, and these parts prevent both. This guide explains what each part does, how to size a pressure tank, and current prices.

Flow controller or pressure tank?
A booster pump needs something to tell it when to run. There are two common ways, and many installations use both.
| Automatic flow controller | Pressure tank + pressure switch | |
|---|---|---|
| How it works | Starts the pump when pressure drops (a tap opens), stops it when flow stops | The tank stores water under pressure; the switch starts the pump at a low pressure and stops it at a high one |
| Dry-run protection | Built in | Needs a separate device |
| Small draws and leaks | Pump starts for every draw | Tank supplies small draws without starting the pump |
| Best for | Simple house boosters, single outlets | Larger systems, borehole supply, fewer motor starts |
Rapid cycling kills pumps. If a pump clicks on and off every few seconds, the bladder in the pressure tank has failed or lost its air charge, or there is a leak. Fix it quickly: every start heats the motor and wears the switch.
Automatic flow controllers
| Controller | Rating | Price | Replacement PC board |
|---|---|---|---|
| PS02.1 (SKD2) | 10 A, 220V | R536 | R194 |
| PS18L | 16 A, 220V | R1 172 | R531 |
| PS01D (SKD11) | 30 A, 220V | R971 | R306 |
Each has automatic start on pressure drop, stop on no flow, dry-run protection and a built-in gauge and check valve, for single-phase booster and pressure pumps. Choose the rating above the pump's starting current.
Pressure tanks
Steel tanks with a replaceable EPDM bladder, rated 8 bar. The bigger the tank, the fewer times the pump starts.

Sizing a pressure tank
A simple rule: allow about one litre of tank for every litre per minute of pump flow, and never less than 24 litres on a fixed-speed pump. A pump delivering 40 l/min suits a 36 – 50 litre tank. The small 2 and 3 litre tanks are for variable speed pumps and the AR200 controller, which only need a cushion for small draws.
Set the tank air pressure about 0.2 bar below the pump cut-in pressure, with the tank empty of water.

Frequently asked questions
Do I need a pressure tank if I have a flow controller?
Not always, but a small tank reduces pump starts for small draws and leaks and extends pump life.
What size pressure tank do I need?
About one litre per litre-per-minute of pump flow, and at least 24 litres on a fixed-speed pump. VSD pumps need only 2 to 3 litres.
Why does my pump switch on and off every few seconds?
Usually a failed bladder or lost air charge in the pressure tank, or a leak in the system. Check the tank air pressure and replace the bladder if water comes out of the air valve.
What pressure should the tank be charged to?
About 0.2 bar below the pump cut-in pressure, measured with the tank empty.
Which flow controller do I need?
One rated above the pump's full-load current. The 10 A PS02.1 and 16 A PS18L suit most single-phase house booster pumps; the 30 A PS01D allows for larger pumps and higher starting currents.
What does a float switch do?
It switches the pump on and off with the water level: to stop a pump when a tank is full or when a sump or tank runs empty.
