Vertical Pressure Kit (220-240 V, up to 1.1 kW)
A vertical pressure kit starts a water pump when a tap opens and stops it when the flow stops, so pressure stays steady without manual switching. Alden’s kit runs on 220-240 V, handles up to 1.1 kW, is rated IP65 and offers four starting pressures for villas and small buildings in the UAE.
A vertical pressure kit is an automatic pressure controller that is fitted on the outlet pipe of a water pump. It starts the pump when a tap opens and stops it when the flow stops. Alden’s kit works on 220-240 V, handles up to 1.1 kW (10 A) and has starting pressures of 1.2, 1.5, 2.2 and 2.5 bar.
Key features of the vertical pressure kit
- Automatic start and stopThe pump runs only when water is used.
- Four start pressures1.2, 1.5, 2.2 or 2.5 bar to match your building.

- IP65 protectionDust-tight and protected against water jets.
- Handles warm waterRated to a maximum working temperature of 60 °C.
- Pump protectionHelps stop dry running and avoid unnecessary starts.
- Easy maintenanceA compact unit that is quick to service or replace.
It is 7 pm in a villa in Al Khan and the whole family is home. Someone opens the upstairs shower, then someone else runs the kitchen tap, and the water slows to a trickle. The pump in the garage is off because nobody wants to walk down and switch it on. A pressure kit solves exactly that: the pump wakes up as soon as a tap opens and sleeps when it closes.
How does a vertical pressure kit work?
The kit sits on the pump outlet and senses both flow and pressure. When you open a tap, pressure drops below the set starting pressure and the kit switches the pump on. When you close the tap, flow stops and the kit switches the pump off after a short delay. A built-in non-return valve and gauge are typical in kits of this type.
"Vertical" refers to how it is mounted: upright on a vertical section of pipe. This keeps the unit compact in plant rooms and under-stair spaces.

Which starting pressure should I choose?
As a rule of thumb, 1 bar lifts water about 10 m. Add about 1 bar so the highest tap still gives a good flow. A higher starting pressure helps taller buildings; a lower one is gentler on single-storey homes and pipes.
| Setting | Typical use | Check before choosing |
|---|---|---|
| 1.2 bar | Single-storey homes, short pipe runs | Highest tap not far above the pump |
| 1.5 bar | Villas with one upper floor | Shower head height and pipe length |
| 2.2 bar | Two-storey villas, long runs, several taps at once | Pump can deliver this pressure |
| 2.5 bar | Taller buildings, long pipe runs | Pump head and pipe rating |
Typical guide only. The pump must be able to deliver the chosen starting pressure at the flow you need.
Applications and use cases
| Application | Typical setting | How the kit helps |
|---|---|---|
| Villa pressure boosting | Upper-floor showers, kitchens | Runs the booster only when a tap is open |
| Tank-fed supply | Ground or roof tank to taps | Steady pressure without manual switching |
| Garden and irrigation | Sprinklers and drip lines | Starts when a valve opens |
| Small commercial supply | Offices, shops, clinics | Automatic demand control |
| Well or tank transfer | Surface pump drawing from a tank | Stops the pump when flow stops |
How does it help? Before and after
| Situation | Manual pump | Pump with pressure kit |
|---|---|---|
| Opening a tap | Walk to the switch first | Pump starts by itself |
| Closing a tap | Pump keeps running or must be turned off | Pump stops after a short delay |
| Pump safety | Easy to run dry or forget | Helps stop dry running |
| Pressure | Varies with the tank level | Held at the set starting pressure |
Pressure kit vs pressure switch with tank vs inverter booster
Choose a pressure kit for a simple, compact, low-cost automatic set-up on a single pump. Choose a pressure switch and large tank where you want long rest periods and stable cycles. Choose an inverter booster for the smoothest pressure on a bigger building.
| Option | Strengths | Limits |
|---|---|---|
| Vertical pressure kit | Compact, automatic, low cost, little or no tank | Limited to about 1.1 kW (Alden kit) |
| Pressure switch + pressure tank | Stable cycles, long rest periods | Needs space for a tank |
| Inverter (variable-speed) booster | Smoothest constant pressure | Higher cost, more electronics |
| Manual switch only | Lowest cost | Easy to forget, no dry-run protection |
Choose the kit when you have one pump up to 1.1 kW and want hands-free pressure. For larger demand see booster pumps and pressure kits or read our guide to fixing low water pressure in UAE villas.
How to choose and common mistakes
- Check the pump rating. Its rated current must be within 10 A and its power within 1.1 kW.
- Check the supply. The kit needs 220-240 V.
- Pick the starting pressure. Based on the height of your highest tap and the pump’s head.
- Check the water. Clean water up to 60 °C. Sand and debris shorten the life of the kit.
- Plan the pipework. Install on a vertical pipe after the pump and add a small tank if you want smoother cycles.
Common mistakes: choosing a starting pressure the pump cannot reach, using it on a pump above 1.1 kW, installing it upside down, and running a pump with no water in the suction line.
Installation and care tips
- Install the kit upright on a vertical pipe, after the pump outlet.
- Fill the pump and suction line with water before the first start.
- Keep the kit dry and sheltered; IP65 protects against jets, not submersion.
- Fit a small expansion vessel to reduce frequent start-stop cycles.
- Check for dripping taps and leaks if the pump starts by itself.
- Have the pump and kit checked once a year.
Safety and standards
Typical practice is to wire the kit through a suitably rated protective device and to have a qualified electrician make the connection. The IP65 rating is explained in the IEC IP rating guide. Check the datasheet for any approvals before specifying it on a project.

Frequently asked questions
What is a vertical pressure kit?
An automatic pressure controller fitted on a pump’s outlet pipe. It starts the pump when a tap opens and stops it when the flow stops, so you do not switch the pump by hand. Alden’s kit works on 220-240 V and controls pumps up to 1.1 kW.
How does a pressure kit differ from a pressure switch?
A basic pressure switch only reacts to pressure and usually needs a tank to avoid rapid cycling. A pressure kit typically combines flow and pressure sensing in one unit, so it can run a pump on demand with little or no tank and also help protect it against dry running.
What starting pressures are available?
Alden’s vertical pressure kit offers starting pressures of 1.2, 1.5, 2.2 and 2.5 bar. A higher setting suits taller buildings or longer pipe runs. We can help you choose from the height of your highest tap.
What power can it control?
The kit is rated for a maximum of 10 A and 1.1 kW on a 220-240 V single-voltage supply. Check that your pump’s nameplate current is within 10 A. For larger pumps use a contactor or a different control panel.
Can I use it with the AMH booster pump?
Yes, it is the standard control partner for Alden’s AMH horizontal multistage booster pumps, provided the motor current is within the kit’s 10 A rating. Confirm the pump nameplate when you request a quote.
Does it need a pressure tank?
A small pressure tank still helps, because it smooths pressure and reduces short start-stop cycles when a tap is opened slightly. Many installations use a kit with a small expansion vessel. Tell us the demand and we will suggest a set-up.
Does it protect the pump from running dry?
Pressure kits of this type typically stop the pump when there is no flow, which helps stop it running dry. Alden’s information also lists motor burnout protection. Confirm the exact protection functions on the datasheet before relying on them.
What does IP65 mean for this kit?
IP65 means dust-tight and protected against water jets. It suits an indoor plant room or a sheltered outdoor spot, but not submersion. See the IEC IP rating guide for the full meaning of the rating.
Can it handle hot water?
The maximum working temperature is 60 °C, so it can handle warm water. It is not intended for boiling water or steam. For hot-water circulation applications ask us before you buy.
Can I use it on a borehole or well pump?
It can control a surface pump drawing from a tank or well. Submersible borehole pumps often use a different control, such as a control box with a pressure switch. Tell us the pump type and we will advise the right set-up.
Why is my pump switching on and off rapidly?
Rapid cycling usually means a small leak, a tank with too little air, or a start pressure set close to the working pressure. Check taps and float valves, then the tank pre-charge. Our troubleshooting guide lists the checks.
Do you install pressure kits?
Yes. Our team can supply the kit with the pump and arrange installation through our service team in Sharjah, Dubai and the rest of the UAE.
